1999 eclipse wiring harness

[auto al]

I bought a gutted 1999 eclipse with the inside up wiring harness all hacked up. The car runs but i have no signal at the obd 2 connector. A lot of the plugs have been cut off going to accessories. It runs but not good. I am going to use the car for circle track racing . Does anybody make a basic harness for this type of application or am I stuck trying to piece what I've got together or a complete harness replacement.
Thank You
