Wiring Harness for Fuel Injector Hookup
1 Attachment(s)
Hi,
I have just had the engine rebuilt a week ago. I put the new rebuilt engine in yesterday and I cannot figure out which Fuel injector wire goes where, and to which injector. I took a picture of the 4 TOP injectors. I know the wires have all different colors. Can someone help with the wiring diagrams for the 6 injectors? I ran across this thread and saw the diagrams but I don't know if its (left to right, or right to left from my photo, and I still have 2 injectors that are circled in red) https://www.rx8club.com/series-i-trouble-shooting-95/fuel-injector-harness-connector-209685/ |
Here is the answer. I looked over it somehow.

This thread keeps popping up when I search and the other linked thread has the harness colors a page or two in so I am going to post it here too. Just to help others searching like my self.
Fuel Rail 1 (two injectors) Both leads for this fuel rail come off of the main harness together. Front rotor injector wire color is light-green and red. (Front Primary 1) Front injector Wire lead has White colored tape Rear rotor injector wire color is light-green and black. (Rear Primary 1) Rear injector Wire lead has Tan colored tape. Fuel Rail 2 (four injectors) The two center (the middle) injector wires come off the harness together and split. Front side of the middle split has Yellow colored tape. Rear side of the middle split has Green colored tape. The two end (front and rear) injector wires come off the harness separately and have no colored tape. The front injector wire is Green and Red. (Front Secondary) The front rotor middle injector wire is Black and Blue. (Front Primary 2) The rear rotor middle injector wire is White and Green. (Rear Primary 2) The rear injector wire is Black and Blue. (Rear Secondary) https://cimg4.ibsrv.net/gimg/www.rx8...37573ebba7.jpg Also found this too. Yikes. Yeah it varies, there really is no rhyme or reason to why some are different. We just did an 05' not too long ago that matched that ^ exactly. But some the wires on another harness we have on hand was different. Everything is properly labeled now when we do it, it's not worth the hassle. |
Yeah it gets confusing, and having personally gone thru the wiring on different year RX-8's I can confirm they are different colors.
There is this as well. https://cimg8.ibsrv.net/gimg/www.rx8...1e066eba3a.jpg |
Mine matched my model year factory service manual to a tee ... ;)

I just plugged mine in the way 9k posted up. Runs great now.
