Well i finally got my LS1 and im just trying to go over every connection before i dive into the swap. I guess you can that im trying to make a map for myself.

Im not sure but i feel like these are for the Cooling fans and Fuel Pump? just not sure plus that little one with one thick wire going to it. thanks guys!

And is this the place where i put the 98 coolant temp gauge sending unit so i can get a reading for the coolant gauge?

 

That's the front engine to body harness connectors. C100, C101, and C105. The single wire is a power feed I think. Go to ls1tech.com and you should be able to find a pinout for those, they don't actualy attach to the engine.

There should be two more by the PCM that are engine to interior harness plugs.

Then should i worry about them then since they go to the body? Yeah there is 2 connectors with a rubber grawment. I would think that would go to the dash of my car (splice) right?

 

I just remember that MR.Dude gave me alot of info on the harness. It clears it up for me big time. The only problem is what if i still want to use my stock A/C compressor? I cant really figure out the wirring. Can some one lend a hand on this
