66 Column Shift NSS and Reverse Light Discussion and Help Needed.

[Nxcoupe]

So after posting up my wtb ad, I realized I was mistaken and needed to refresh my antique memory with what all my car had and didn't have. What I really could use is pictures of under the dash, specifically the reverse light switch wiring. Also, I need to know if a 66 neutral safety switch will work in a later model trans with the 3 prong switch. I am attaching pictures of what I have. I figured out that I just grounded my nss wire to the firewall, and I would like to put the correct NSS into this trans so I can hook up my NSS wire properly.
So the reverse wiring is what I don't have and need info on. Here is what I have. I need to know where the unpinned gray wire I'm holding goes to. Any help would be greatly appreciated

center pin on the 3 pin is ground in park and neutral.
simply attach relay terminal ( lower right spade , brown wire on your relay ) for relay proper operation

Switch on your column shift car is backup lights

Should be able to hook those 2 with the outer pins on the nss and eliminate the column switch.. not stock but better

I would like to know if the 66 switch can replace the one that's in there. Yeah, I figured out the reverse switch, just been a long time since I messed with this car. I need pics of the woring under the dash and on the firewall for the reverse lights with a column shift.

" I think" the rooster comb ( aka manual lever ) in the trans is different.

You have a correct 66 trans pull its pan and compare ????


edit, the trans in MY car is a 1970 model. and it has the correct 66 NSS.
But I do not know " IF " the manual lever has been changed , or not.

Ok, so maybe the nss only hits the neutral and park part of the rooster tail, I seem to remember from my fog of a b tree ain that the nss and reverse combo switch had an extra part in it that extended or was tripped in a different fashion than the neutral sense was. Worse case is I try it and it doesn't work.

Still need pics of the reverse wiring for a column shift.

Dredging the memory bank, think the “rooster comb”(?) doesn’t have the plastic thing on it for early NSS switch only. Plastic is on for the 3-prong switch.

Not certain, but gray wire almost looks like it goes to oil sending unit on back of engine.

It could be. I would have to see if I have one connected already.

Could be right, good call.
