LB7: LB7 Injector Harness Help

[gmasko]

Putting my LB7 back together and just realized that I failed to mark the locations of the injector harness wires to the injectors like I usually do. Now I'm kicking myself in the rear and need some help understanding where they go. Are these +/- wires? I don't see any markings anywhere and I just flipped through my Haynes manual to try to find the electrical schematic and I don't see it. BTW Haynes says messing up the location is a big no bueno and that got me worried. Any help would be greatly appreciated!

Post a pic of how you have it now. The harnesses only go on one way in theory.

In theory yes I can see how they've formed over time but the clips on two harnesses have broken off. So the wires can go either way, 50/50 chance I short the injector out, the way I see it.

Red wires on #1 injector.

Are you asking about putting the wrong set of wires on the wrong injector or are you worried about having the wire swapped on the injector studs?

On the injector studs.

Any will work. The injectors are not polarity sensitive. The solenoid is just a coil of wire. It doesn't care which way the current flows

Correct, as long as each pair is on the correct injector.

Exactly what I was looking for, perfect explanation. Thanks guys! Freaking Haynes manual getting me all worked up
