LS 5.3/4L60E into my 93 SCSB.

So I've been taking notes all day in my notebook.

Gauges are covered. No questions there.

Fuel pump. Got a couple part #s wrote down here. No problems.

Harness. I was reading this post: http://www.ls1truck.com/forums/showthread.php?t=9535&p=131558#post131558

And it dawned on me that those wires needed to go inside the cab are leading from the PCM, correct? I just need to cut them loose and extend them from the PCM to locations listed?

Questions...

Red 17: AC Request - Im not running AC so I imagine this is of no concern to me
Red 30: Fuel enable control - What does this hook to?
Red 42: TCC Solenoid Valve Control - What does this go to?
Red 50: Vehicle Speed Sensor Signal - To my DRAC box behind the glove box, right?

I'm considering simply putting the '02 fuse block in my truck. I noticed it has multiple studs on it for hooking up power/ground. Where/how do I hook up 'ignition/run' power? I know where to get those from on my truck of course, I'm just not sure how/where they connect on the LS harness to make it function correctly.

Thanks.

Look here http://www.lt1swap.com/underhoodfuseblock.htm
ignition power goes to a pink wire on the that black connecotr with like 12 or so wires on it, next to the blue one. And also on the underhood fuse block that link shows where it needs to go.

Water temp most use an adapter and put your guage sedning unit on back pass. side of head. there is a plug there.

I think on the a/c request you can have your programmer turn that on for a fan control wire if you run electric fans.

Looks good fellow FSC member.

Are you doing anything to the 5.3 before installation or no?

Hey. Nah all it may get are the conversion long tube headers...just to make getting exhaust put on easier. That and the computer tune will be it. And whatever kind of intake I put together for it.

Thanks. I sat at the computer for about 8 hours yesterday, visited 4 or 5 websites and took 4 pages of notes. I think I have just about all my answeres covered. Looking forward to doing the swap.

I'm in the middle of mine now on a 89 suburban. Any ? let me know. But going off lt1swap info is dead on so far. My fuel pump fires off the ls puter so far, and starter turns over too. I need to sort out my exhaust then try to start it.
