LS2 in Monte SS
LS2 in Monte SS Hi all, I'm a newbie here 
I'm looking at putting an LS2 into my Monte SS with a 4l60e trans. I have a few questions that I've been searching for a while. In terms of the harness, who makes a real good one that is complete? Do I need to stay with the "drive by wire" throttle body or can I retrofit traditional cable throttle body? If I have to use the "drive by wire", which pedal assembly should I get? Will any LS series 4l60e trans work or do I need the ones that only came with the LS2? I would like to find a donor car but they're pretty rare. I might just get new stuff. Thanks in advance.

Speartech is a sponsor of this board and can probably help you with the wiring.
I am pretty sure you would need to stick with the ETC since there would be no real way to program the compuer to handle a cable TB.
I think though you could use an LS1 style computer to run it all and then you could go with a cable setup.

Speartech is the man and can definitely help with the LS2. Great product and great service. As far as the ETC goes, I think it is the way to go. I have it on my LS1 and love it. Very responsive and built in cruise control. Good luck with your swap, there are several LSx MonteCarlos here on the forum, including an LS7.

since you're buying a harness, any plug diffs (for example, some have the VSS on the other side of the trans) can be accommodated for.
