71-74 Ralley Cluster HELP

[74SRT]

So I think ive messed up.. Ive been hunting for a 74RR cluster for my 74 Satellite. I bought a 72 cluster from a charger. I keep hearin that the 74 is different but ive been looking and just cant see how? I dont have a harness for it yet but my question is will it even work on my 74?? If so would I use a 72 or 74 harness? Help???

 

[74SRT]

Someone PLEASE help me out ASAP

Here is a link to one member Joel has, He very well may know the answer to your question, and could have the one you need. im pretty sure the fitment is the same, but don't take my word for it, don't know about the harness itself, hopefully he can help you in some way with this.. Good luck.

i thought all 71-74 rallye clusters were the same?

 

[moparmarks]

71 cluster is one year only in that it take the 71 only wiper switch
72/3 are the same
74 has the little indecator lights for the H/L and wiper switch. 74 had a 120 speedo but some have be changed out to the 150.

71 harness
72/3 harness has a different pinout at the bulkhead
74 harness has the seatbelt interlock.

You can mix and match them but you'll have to change the pinout at the bulkhead the match the front harnesses. Think that there are some other differences. Maybe Nacho will chime in. He knows better than me of all the differences.

The ’74 additional illuminated labeling around the headlight and wiper switches is a cosmetic change to the bezel only. The ’72 cluster will physically interchange with a ’74 rallye cluster. If you a going to source a complete rallye dash harness, with the least amount of work, find one for a ’74. Another option for those with some electrical skills is to rebuild your existing standard harness to support the rallye cluster. Requires at a minimum the connections and sockets specific to the rallye cluster all years. Wiper switch wiring needs to be extended to move it from the right side on the standard to the left for the rallye. Recommend having the FSM wiring diagrams for both the standard and rallye clusters on hand. Done correctly its fully functional and indistinguishable from an original rallye harness with no concerns about the year specific changes to the remainder of the dash harness. I’ve done it several times.

Changed over standard harness;

Thank you for the imput! So the 74 harness will work for a 72 cluster?

 

[72RoadrunnerGTX]

Yes, ’74 harness will support a ’72 cluster. The basic electrical functions/connections of/at the rallye cluster are the same all four years. Backlighting, indicator lights, gauge connections, voltage limiter are all the same. I have noticed a slight variation in how the wires were routed and wrapped directly behind the cluster over the various years but bulb/socket count remained the same. There were some minor variations at the heater control, stick with the ’74 A/C heater control. Keep in-mind there were two different rallye cluster layouts, with and without a clock/tach. Gauge placement/location was different but connections/harnesses were the same.

 

[YY1]

Just thought I'd add that the gauge placement is different.

Early cluters have a clock or tach in the right hand "large" pod, and the other gauges "duplexed" in the remaining "small" pods.

Later clusters have the fuel gauge in the right hand large pod, precluding an aftermarket or repalcement tach from being housed inside the cluster.

 

[72RoadrunnerGTX]

Going to have to disagree slightly, wasn’t an early/late thing that determined which version rallye cluster was installed. Both the clock(J21) and tach(N85) were options for the cars that came with rallye dashes standard. Couldn’t order both however, if neither was ordered the car received the gauges in the larger opening version. My '72 came with a no clock/tach version and tachs and clocks were available in later years.

 

[moparmarks]

72RoadrunnerGTX pretty much summed it up for you. Glad he likes to type more than me. Here are the two clusters.
Standard Rallye
Clock or tach option cluster.

all rallye clusters will fit on any car with rallye harness already on it

Phisically you have just to be aware on 71 wiper switch where wires are the same but switch and plugs are not ( diff prongs disposition ). Not a problem, just reuse the switch already on car is enough. all switches fits on all clusters

some differences have been already posted. I will just confirm or correct. Or you correct me if I miss something

-housing changes just if is clock/tach or Standard rallye IN ALL 71/74 B bodies
-Gauges changes accordling with housing setup... big dual meter and two small individuals, or 4 halfs to the small dual meter setup.
-Bezel only changes in 74 due the small icons added.
-lenses changes only if Standard or clock/tach, to the clock reset shaft hole.
-150 speedo for 71 72 and some 73s... 120 for the rest of 73s and all 74s.
-74 speedos with blue high beam indicator ( rest are red )
-71 wiper switch diff than the rest ( this makes a difference on plug setup on 71 harness ), beside this, VARIABLE SPEED was only an option for 71s, so in 71 we got 3 diff wiper switches, and 2 options for the rest.
-71/72 uses an all horizontal switches/levers disposition on AC-Heater control. 73/74 got a vertical switch for blower speed. beside this, the OFF position in 71/72 AC control is in the middle... 73/74 get the OFF position far in the left side. This makes also a diff switches on all functions between 71/72 and 73/74.

Now underdash harnesses differences in relation JUST with cluster and parts related:
-tach is just an added harness
-clock gets an extra jumper wire from ammeter stud.
-clock/tach and standard setups gets a diff limiter jumper wire due the different distances between gauges.
-as has been told the wiper plug changes to 72 and laters... but wires are the same.
-it happens the same to the BLOWER LEVER switch plug on AC control between 71/72 and 73/74. But control unit keeps the same plug. this is however a diff harness for A/C function.
-71/72 A/C-Heater control uses dual bulbs for lettering light. 73/74 uses single bulb

In relation with all the car:
-71 uses a diff driver side door jam switch plug ( three pins ) than laters
-71 seatbelt light is sourced by the time delay flasher ( same then the ign key courtesy light )
-72/73s are EXACTLY THE SAME underdash harness wiring in everything, with seatbelt warning system ( not anymore with time delay, now working with gear on tranny ).... JUUUUUST maybe couple of wires changed in bulkhead disposition. ( I can't recall exactly that detail ),
-74 underdash changes AAAAAA LOOOOOOT... due the seatbelt warning system now interlocked with seats and seatbelts sensors ( if Federal ). Canadians are the same wiring, but control unit changes being not interlocked. However nothing of this affects the Rallye cluster interchange. I can post every diff between 74 wiring and earliers if you wish. there are some extra wires running to bulkhead, A/C Harness goes through firewall due the lack of cavities available after the interlock extra wires added, around 4 wires were turned around on bulkhead ( starter relay, brakes failure warning switch, wiper washer, horn, maybe some others )


SOOO YES... if you want to make everything works on your 74 satellite, better get the correct 74 Rallye harness. If you want to make work another year harness, some mods will be required to match everything and make everything work

Oh! another difference! the wiper knob on 71s is hold with an allen screw... rest are pressure

 

[Nacho-RT74]

you can also get a CLUSTER PIGTAIL LOL ( like the first pic posted by 72RoadrunnerGTX ) and splice it on your standard cluster multipin conector, like he said. Sometimes when you buy a cluster it gets still this section of harness attached.

Is not realy hard to do!!! just need to match the colors!!! rallye and standard clusters used BOTH same color keys for every function!

the only difference you can get is on rallye clusters the gauges works with accesories source, and on standard the gauges works with RUN source. This is because the idiot oil light. This will make to add some extra wire to make it right.

which BTW will require to change the oil sender

Lots of good info for cluster swaps.

I'd been trying to figure out the clock/tach thing, and thought I had it down to years.

Guess not.

Seems like an awful lot of work, and inventory (not to mention labor and general non-cost effectiveness) to have so many different configurations.

 

[moparmarks]

Sorry Nacho friend but 71 has its own wiper switch. 72/4 the switch has an index knotch so the switch only goes in one way. 71 does not. So a 71 switch will fit 72/4 cluster but the 72/4 switch will not fit the 71 cluster without knotching the hole. This is also for 72 build before 9/2/71.
Also all non-Rallye wiper switches are alot longer than the Rallye switch.

 

[Ron 73]

As many times as these things and related with the Rally clusters come up, we could use this as a sticky.. ?

 

[moparmarks]

Here be the wiper switches

 

[Nacho-RT74]

yes, all you say about the notch for the wiper switch can be true... I don't recall. The 71 cluster I got from ebay got a variable speed with it, and I kept it to convert my 74 on variable speed control ( not originally optioned on 72/74 ) when I get the 3 speeds motor.

BUT initially I CUT and modified a 2 speeds STANDARD CLUSTER wiper switch ( which as you said is way longer ), to make it fit on the rallye cluster ( rallye cluster stuff is not available locally ). I don't remember if I had to make the notch on housing or remove the key on switch, or it was enough clearence to fit it, no matter if tight.

Then found a 74 bezel with switches icons, and installed on the 71 cluster, then reinstalled the 71 variable switch since by that moment finally got a 3 speeds wiper motor. What I did is change the plugs for it. THANKS GOD, the 71 cluster also got attached the pigtails LOL so didn't need to find those plugs ;)

IF THE NOTCH DEAL MAKES A DIFFERENCE, then the 71 housing could be a diff piece from the rest just for the unexistant notch for wiper switch... unless it was a small mod made on factory when assembly. Not a big deal though.

I have a doubt, maybe a little bit of topic. There was 2 speeds, variable speed and 3 speeds switches on 71 making a 3 options in total ? or just 2 speeds and variable ? what I know they were 3 options for the wiper function, but I can be wrong


BTW AND FOR THE TOPIC... HEADLIGHT SWITCH IS THE SAME FOR STANDARD AND RALLYE ( all 3 rallyes )

Is not that hard, just that maybe how I explained it, looks to be LOL. ( english is not my mother language )

 

[moparmarks]

71 and 72 built to 9/1/71 had either 2-spd and Ver-spd. Cars built after 9/1/71 had either 2-spd or 3-spd. 3-spd replaced the Ver-spd on 9/2/71
I have around 10-20 Rallye clusters and lots of parts. If I get some time I'll pull it out and get some referance pics for ya.

Ron I agree that a sticky would be nice I am changing over to a Ralley dash and looks like I will need to get a harness
