I have had this info for about 3 years now and I have been emailing it to those in need. By popular demand,here it is posted on the forum.

You need to get a Haynes manual for ’79 to ’83 280ZX. This is the one with the red cover. Look on page
252, this is the wiring diagram. You will see 3 plugs labeled “1,2,3” with circles around the numbers. This
is at the lower left-hand side of the page.

The wires are as follows:

Plug 1= BR 12v power source. Positive

G 12v power source. Positive

Plug 2=Y start signal (+)
GL ground for inhibitor switch
YW speed sensor (not necessary)
Y A/C signal (+)
YW coil (-) (must use ignitor)
B fuel pump ground if using modulator

Plug 3=LR fuel pump relay
G ignition .signal (+) for air regulator
W not used
Y not used
BW ignition signal (+)

Good luck to all who are doing this conversion. If hooked up correctly and no other problems exist, your car will start right up. Just make sure you use the ignitor for the coil. The engine will not run without it.

Re: LOOK! Here's how to wire 280ZXT harness into 2

Thanks for taking the time to post this Ian. I am getting ready to tackle this part of the project (wiring scares me silly).
