Wiring the fuel injectors!

[tropical 87t]

During disassembly of the engine, I forgot to label each fuel injector wiring harness. I tried to remap them by the Cygnus wiring diagram but I am still confused. Does anyone have the exact wire colors for each fuel injector wiring harness for cylinders 1 through 6? (1987 7M-GTE)

Let me look at mine.. I had the same problem when I did a rebuild last year and I had some trouble finding the right injector plugs on the harness that went to the right injector..
#6 black wire and a white wire with red stripe
#5white and red wire
#4 yellow wire and white wire with blue stripe
#3 white wire and wite wire
#2 black wire and a white wire with red stripe
#1 yellow wire and a white wire with a blue stripe.
Now this is for the 88 turbo harness
Which should be fine for a 87 turbo or n/a for that matter. Good luck.

this is correct, its a batch system

#1 & #4 are the same (yellow and white/blue)
#2 & #5 are the same (black and white/red)
#3 & #6 are the same (white and red)

they fire in pairs above so those pairs are interchangable ( #1 with #4 for example), however they are spaced on the harness so its easy to figure out.

I just did my 89+ brand new harness and I think they are all the same. My soldering skills has something to be desired though!
