I just bought this harness off of here and have a problem.I was told that it would work on a 2000 z28(My car).It doesn't have the same connections right by the computer that go to the passenger side firewall.It doesnt have the connections to go into the car for the inside harness. What does this look like it came out of? I need the right harness soon because i have to break everything in before my dyno tune in a few weeks. All the help i can get would be nice.

looks like it came out of an automatic car!

 

Yes it has a 4l60e plug but nothing else.Also the connections for the injectors are totally different.

 

Anybody know what injectors had a different plug then the normal ls1?

 

Well i found out from the seller that........

The harness was removed from an 03' Sierra with a 5.3l. All of the harnesses that came with an auto trans should be the same. I'm not really sure of the extra connectors - it might be for traction control on the trans. Can you take a picture of it and host it somewhere? If you can, I might be able to figure it out.
