what wires are these

[74 challenger]

this is a 74 challenger 318 ac car. 1st wire 2 yellow with black tracer female plug,located next to fuse box main harness is this the ground for fan switch?2nd white plug behind air cleaner,is this part of the wiring harness or did last owner hack this in?

Wish that I could help but my pictures don't show those wires. I took several pics of my harnesses prior to removal.

I have a 74 here that has not been messed with. I'll email some pics to you of the wiring harness.

thanks todd

 

[74 challenger]

anyone know the 1st pic?

is it a fuse holder ? it looks like the old glass fuse twist lock type if so it is not stock .Yellow & black are typically used for the dome light cicuit or the key / ign light which has a timer so if it is a bayonet type plug it is probably for the timer harness

 

[74 challenger]

everything works thats why i cant figure it out,its some kind of female plug

In the second picture it looks like about 5 wires are cutoff just below the large plug and blue wire. Are they hooked to anything?

Leo,im buying a new harness.Last owner had the wiring all hacked up,surprised the car ran.Im thinking this is why i cant figure why the car is over charging.

Great news. Electrical can be confusing enough when the wiring is not butchered up.

could the 2 pic be a ground for the ac controls,my used dash harness im putting in has the same plug on it

I thought you were getting a "new" harness. The engine compartment harness is only about $150.00 new from YearOne or anyone else you buy parts from.
