Two used BlackBear harnesses, one was on my suburban and the other was on my avalanche. Both work and are in good shape, both have 2005+ truck fan connectors.
2 pin style for 2003 up trucks, but if you need a 1 pin with ac tap for a 99-02 truck I can modify the harness for you.
I'm pretty sure you can use the 2 pin on the 99-02 pcm. I've used 1 pin before and didn't like it just due to fact that the fans were going on high all the time with the a/c. But correct me if I'm wrong., it's been a while since I've looked at this stuff.
