wiring harness
wiring harness Ok..I'm putting an LS1 out of a 2000 Z-28 into a 95 Z-28. I got a harness out of a truck but it seems there are a few differences. Like after the #2 injector on the stock harness there is another sensor clip. On the truck harness there is none. Should I just get an LS1 harness to fit this application (fbody)? Anyone know where I can get one?
Thanks!
Thanks!
Thr truck engines use different injectors which is why the connectors are different. Also the coil connectors are different for the truck engines. There are some companies that make harness adapters for the injectors and the coils, no need to purchase another harness.
Another difference with truck harnesses is routing and most importantly lack of fans. I removed the pins from the connectors I didn't need (evap, EGR, etc.) and added pins where the fan control relays went. I also used connectors from another vehicle and spliced them in my harness instead of using the adapter plugs since I already had the soldering iron hot.
This is the harness I used and it was perfect... it's all brand new and comes with all the connectors and everything.. the only thing you have to supply is the fan relay(s)

Wiring I used the truck harness but I'm also running an external SPAL fan pulse width modulator. I will say i've been eyeballing those harnesses on Ebay.
Hey 2165: how did the routing on that harness go? Also how big is the hole needed to fit everything into the cab?

So I have the harness that came with the T56/ls1 and have started removing all the stuff I don't need but am wondering where to get the fuse/relay block that is used? anybody know where to get the one the harness on the ebay is using? that is a good deal on there cause most of them I have seen are 750$ or so. but I would like to make the one I have work. I have been able to connect power and all the wires for the data link and was able to download the tune with my EFI Live so i think if I knew where to get the right fuse block I can do the rest my self.
