ZXT_bean Posted December 2, 2009 Share Posted December 2, 2009 Ive been racking my brain with wiring diag. Haynes manual, the FSM, and I still have some questions as to the correct wiring. I have labeled 2 pictures. Im trying to swap the 1980 280zx EFI into a 260z, Im not so much worried about the 260z wiring as that is all very well documented. Most of the wiring harness was easy to figgure out, but I dont want to botch this up and fry an ECU. There are 3 harness plugs labeled. Blue/White (thicker gauge) 12v+ Blue 12v+ Blue/Green Fuel Pump relay? Blue/Yellow I have no idea.. Yellow/Black Starter signal. Will I need to hook this up? There is the single Yellow wire by the ecu harness. Is this the 12v+ switched signal wire? I appreciate any and all feedback. Thank you Quote Link to comment Share on other sites More sharing options...
JSM Posted December 4, 2009 Share Posted December 4, 2009 See if this wiring Diagram is any easier to read through. http://i636.photobucket.com/albums/uu85/jeffreysm/1980zx.gif I downloaded this from autozone. Quote Link to comment Share on other sites More sharing options...
Gcontrol Posted December 12, 2009 Share Posted December 12, 2009 Use the FSM. You can find it here. http://www.xenons130.com/reference.html Quote Link to comment Share on other sites More sharing options...
