LQ4 Wiring Harness Ground Question
LQ4 Wiring Harness Ground Question Ok; I reworked my wiring harness over the weekend (man was it slow and painful). I layed it back on the engine last night and I have two grounds that connect (screw in) to the block. I was using info I got off of lt1swap and it is saying that I should have had three grounds. I honestly can't remember how many I took off. I've searched a lot; but can't find; Does anyone know how many grounds are on a LQ4 harness?
Thanks,
Brian.

Make sure to have a really good ground to the battery and then to the body and frame. The last 2 are often overlooked and create some big problems. Sometimes I feel like I have grounds that ground grounds but all of my issues have evaporated.

4 grounds I have a ground on my 2004 yukon Denali comes off main harness on driver side and goes to the side of alternator & power steering pump bracket. Does this sound right?
