I had a local guy rework my ly6 truck harness to fit the engine with a ls3 intake. To make a long story short it took 6 months to get and it is a pos, nothing soldered and missing the oil sensor pigtail. The engine is out of a 2009 gmc. Does anybody know where I can get the wiring harness schematic for this engine, I can't seem to find one, so I can wire up the new pigtail. Also, how about the conversion for this harness. I am gonna try to fix it if I can. I was looking at the pinout on LT1swap but not sure if it is for a 09 with vvt. It is a 09 6.0 ly6 with a texas speed cam with vvt and t-56 going into a 73 Camaro. Any help would be great. Spring is a coming! Thanks Jeff.

Diagrams on lt1swap are correct. Oil pressure signal is on X2, pin 50, circuit 331.

What are you doing for VSS?

I have a set of gauges from speed hut. The speedo is gps unit. The tach, oil pressure, water temp, and volts will run off the can signal from the ecm. The fuel gauge is separate. It will work off the voltage from the sending unit. Thanks for the info on lt1swap. The pig tail I have has 3 white plain wires coming from it and I don't know which one is for the tan and white wire in the harness or what the other two are for. Pretty sure this dude and I are gonna have a day in court, the thing is a mess! Jeff.

You need the help of a multimeter my friend. You can use it to check continuity between the wires and the corresponding pins.

Gotta love those pigtails, the attached should help.

Thanks. That is just what I was looking for. Can I ask where you found that? Looks like a good place to find a lot of info. Just checked with the court system here in Ohio, I am gonna try to make this guy pay. He screwed a bunch of others on here to. Thanks Jeff.
