An someone please tell me what this blue wire with the islet goes too. It’s with part of the coil harness . Doing a wire tuck I think it goes to hot side of solenoid but not sure can anyone maybe check their car or know off the top of their head ?
Here I see where it was at I can’t see the blue wire tho......

That’s what I was thinking the other one wire with the single plug is a ground so I don’t think it’s. Ground or they would have rn them together
