Injector plugs mix up
Ok ok i know im an idiot. The plugs from the harness on my 96' were marked so i supidly assumed these were too. Putting things back together realized they aren't.
Now they only come out of the harness in four pairs, 2 pairs per side so that makes it somwhat easier but how do i know what plug goes to which injector? The wire colors on each side are the same so thats no help. Any advice?

TPIs are batch fire. that means 4 injs on 1 side fire, then the 4 injs on the other side fire.
Its hard to screw this up.

Re: Injector plugs mix up
Hence why the wires on each side are the same color? So basically as long as the harness is on the correct side of engine it won't matter which plug goes to which injector?
