wires to isc

[marc1131]

Hello all. I have a problem with the isc wiring. There are 6 wires going to plug, 2 of them are black with a red stripe. The question is, does it matter if i switched them by accident? If anyone knows what they are for and could give me a helping hand, it would be greatly appreciated.

i could be wrong but i believe they are sensor grounds, one that comes from the ecu and one that grounds locally. someone correct me if i'm wrong.

they are actually two grounds but they alternate and yes both need to be connected correctly

shitty. guess i'll have to figure out which goes where. will it throw a code if not connected correctly?

Here you go. No the blk/red strip is power and they connect together anyway. The others do matter. The ecu sends the ground on the other four and it controls the coil at that specific time.
