Need Help with Wiring Harness 77 280 A/C


Recommended Posts

I am completely restoring a 77 280z with air conditioning. In the process of putting it back together, I found the wiring harness that I am using 24012N4800 does not have the leads for the air conditioning.

The leads go to the A/C Pressure SW, Magnet Valve-F.I.C.D & Magnet Valve-Vacuum Source for A/C, and Compressor release for A/C. Is there an A/C harness or do I need to make a harness and if so how or where do I splice it into the main harness?

My early 77 280z (09/76)  has the A/C wiring built into the main harness (not the EFI harness).  So, there must be that option out there.  Ive seen many variations on the A/C components on these cars so, not sure how many harness revisions there are but I would guess many.  

Hope that helps, good luck
