I’m helping a buddy do a LS swap on his sons truck. I did one on my C10 and did the harness myself and had zero issues. Pretty straightforward if you stay organized.

Started working on the harness for my buddy and I’m confused by a couple things right off the bat. I’m wondering if this Is a usable harness. It is a Red/Blue version which we need. Hoping someone can point me in the right direction on a couple things.


1) see pics below. I know I need to cut the C100, C152 and C153. Two of the three looked completely normal and I cut them. But I don’t know what connection this is that’s pictured below. It’s doesn’t look like any of the three connectors in the instructions I follow. It’s too big ti be a C153. Any ideas?

2) on the C2 block, I’m suppose to keep A8 which is the battery positive terminal to PCM. There is no wire in the A8 location. Never has been. I’ve checked 10 times ti make sure I’m looking at the right location and I am. Any ideas?
