yeah i've already had to fix some odd miswirings that I don't think I did.. I believe the harness I bought was crossed, but it's fixed. the meth pump only turns on when the ecu is off but the key is on, but functions properly when key and ecu are powered on.. the key doesn't power my ignition or computer. So it's just kinda weird that the computer outputs revert to ground when off. But that's an easy fix, I can run the 12V trigger wire for the relay to the meth pump to the fuse assembly that powers on with the ecu. I also need to wire up the oil pressure transducer.
