BTT... I've got my harness almost finished, Just have to get all the pieces for the fuse block and relays. I've followed the instructions and pin-out charts on www.lt1swap.com. This page makes it a breeze especially if you are familiar with GM factory stuff. I will try to post pics of my harness this weekend when I get it all taped up. I'm going to try to get to the JY friday to get the parts to build the cam sensor pickup. I've got a GM 1X sensor I just need the reluctor and adapt it to an old distributor. FWIW The drive-by-wire stuff is all pretty much self contained into one connector and gets rid of the IAC and TPS. I like the idea of being able to place the TB in any position as my inlet from the intercooler comes in over the pass fender. It will make TB upgrades more expensive but it looks to be atleast 70mm so I think it will feed all my engine can take. Also the later 2005 harness I have also integrates the IAT into the MAF sensor.
