1968 Chevy SWB Fleet. 2002 5.3 all stock (for now) Nelson Tune 4l60e w/TB converter.
ok not stock anymore...13.3 at 101
Now with front mount turbo... new times soon
Theres a green wire & a black wire, both together, that comes out of the LS1 harness, with a plug on the end, correct? This just plugs into the compressor. Or, do you have something different? Who did your harness? Theres a bit more to the A/C wiring that needs to be explained. You need to install a different pressure switch than what you have , etc...
