Title: New M&H Rally harness - Mystery plug??
Post by: chaps70rt on June 12, 2023, 02:46:02 PM
Hi all..... just preparing my new rally harness for my 70 Challenger installation and was curious what this plug in the middle of the harness is for??  The wire is black with a white stripe. (see pic)

I can't find any reference to it in the coloured wiring schematics.    Anybody know what this was added for?

Thanks .....

That is the power feed to the fan motor. Stays connected that way if non a/c car. If a/c car, that disconnects and plugs through the a/c sub harness then to the fan motor.

Wow ..... I completely missed that level of detail on my colour schematics.    My car is a A/C car, so there is that A/C harness.    It's all starting to make
sense now.

Thanks Jay Bee and FE5Cuda ........ you saved my bacon.
