i just put my l28et in my 78 280z and i have everything bolted up but i desperately need help with the wiring. i have searched all over the forums but wiring just isnt for me. so i live in danville ca. which is like ten minutes away from walnut creek, if anyone knows how to wire my car that lives in the bayarea will help me, i will pay you 100$ cash to finish wiring my car. call me for details, 925-487-9302 or just pm me. michael

Click the link above and the third picture from the bottom shows the connector you are asking about. I mention what they are for in the description above the picture. I did go ahead and ground the green/blue wire and I suggest you do as well. My car is actually tearing up the road now so I will be doing a full write-up as soon as I catch a sunny day to take some pics so that might help you as well. Looks like you're close! :icon6:

When I did my turbo swap years ago this the what I used for my wiring

 

 

 

 

 

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 (-)

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 (+)
