I got my standard dash put back in and everything hooked up. I have mysterious yellow wire that has a plug in it that comes out of the column cluster with the other wires. I'm sure its important. Just can't figure out where it goes. I also have a black wire by fuse box I can't trace down. And one blue wire behind radio. 20150129_170207.jpg20150129_170056.jpg20150129_165727.jpg Help please.
 
My '71 FSM shows yellow as part of the dome light circuit? Is there a connection on the headlight/dimmer switch that is not part of the large connector block?
 
I'll have to check tomorrow. Thanks. I have a diagram,but it for Ralley harness
 
That wire looks like it is in the right place (and right length) for the brake switch, although I think that wire is white, not yellow. One of the connectors for the brake switch is pink or red with two wires, and the other is white with a single wire (at least on a 70 Road Runner).

Do you have all the wires connected for your brake switch?
 
blue wire behind the radio, accesories feeded from run circuit. Usually power optional trunk lid, and/or power windows trigger for remote on.

yellow wire... The door jam switch gets a yellow wire ( also a black one just on driver side ) but I recall they are terminals isolated by shrinking tube, not plastic plug.

My next guess would be the source for the ign key courtesy light ( if you got the flasher ), which runs to steering column. if so, you must have a single yellow wire with male terminal hanging out from column, aside the ign switch and turning switch harnesses

no, is just one piece block

hmm, I know on 69 RR's there was an option to have a lights on buzzer that wired up near the steering column with a black power wire at the fuse box, that situation looks just like that.

Check out this wiring diagram

they are black wires, not yellow
 
The yellow wire is for the light bulb by the key switch (right next to the 4 way switch) it connect s to the dome light / door switch wireing I just did a coulm swap so it's still fresh in the head the rest I'd have to look at my car

The black wire by the column might be the other end for the yellow one if it fits (unhook battery before you try) if it fits UN plug hoo battery back up open your door and then test for power there if there is power close the door and retest if power go's away that's the other end , if no powers ether way it might be your wire still you just have a problem down the wire somewhere , mine plugged into a black wire now that I'm thinking about it hope this helps you out good luck

Ok last time I just looked at the pics agen the black wire by the fuse box would just plug in at the bottom of the block in one of the two slots it would say acc , what it powers would be an optional item like rear defrost or something (plug it in and see what works) if it arcs the item is tured on maybe make a jumper wire with an inline fuse plug it in then just touch the other wire see if the fuse pops or not then go from there good luck and try not to burn the car down sorry I can't be more specific what the black wire does I don't know what your car has in it
 
nacho this yellow wire with the female plug is the one hanging from the steering column.. im sure its for the courtesy light as you say,but i cant find a male to plug it into. it can reach almost all the way to the ac switch and almost to the ash tray...
 
Dunno why I recall this being male and not female ( whatever )... The delay flasher got its own harness, which plugs into a pink fee/mold ( constant batt ) and to a black feed/mold with yellow wire ( door jam ground ). Both are bullet teminals... then another yellow wire to feed that bulb.

Is true, on 3rd gen harness shows a male plug.

allong 71/74s, some changes made. Your car could get a 3 provisions door jam ground mold instead a single one like diagrams and pics shows. I recall mine ( 74 ) having a 3 provisions mold ( where I plugged the map light allong with courtesy light )
 
I recall the cylinder but I believe its behind the ashtray,but I'll double check. Man wish I would have taken more pics so I would know this one stand alone yellow coming from steering column. Door jam light switch wires are hooked up correctly. I personally redid those and yes they were females that plugged into blade fuses. Thanks for all help guys
 
Damn! didn't notice the question about the black wire.

Black wires arriving to fusebox/bulkhead are:

--Horn wire or key in buzzer--fusebox section. Check if the 4 cavities for horn relay are full. Can be either for key in Buzzer or horn trigger from steering column ( two of those cavities get black wires... the other two are green traced red and violet )

--Brake warning light---bulkhead section... must be an empty cavity left on bulkhead ( cavity 24 by 73 diagram )

around ashtray you can get the turning flasher. diff stuff

It appears that some of my photobucket pics have been liked here so I will add my two cents, as mentioned the yellow leads to the key switch illumination lamp, black wire near the fuse panel is the key in switch buzzer ground. Commonly removed from it’s cavity at the horn relay to disable the buzzer. The dark blue wire with the female insulated spade connector is labeled in the FSM as for power windows, likely trips the power window safety relay.
 
yes that is correct yellow wire.. i just have to find out where it plugs in. nacho said to look for the small round cylinder and check that.. i will as soon as i can get back in the car.. thanks guys

Hmm kinda sounds like what I was saying lol

That is correct, one of the pictures linked shows the timer/relay and its related harness, including the connector the lamp lead plugs into (noted by "to lamp");

No, not really, nothing to do with a lights on buzzer, big differences between ’69 b-body dash wiring and ’71-74. No key in ignition buzzers until ’70, combined horn relay/key buzzer fuse box mounting started in ’71 for the b-body. The black wire is not a power lead, it is a ground via the key in ign. switch micro switch, via the left door jamb switch.
 
I'm gonna have tonget back under dash and find the yellow wire that your showing coming from dash harness and plug into column wire hanging, then I'll just work on the black wire because it seems I'm getting a couple different answers on it.
