Man Chengny, you're dropping information left and right!
I stripped the original main cab harness out of the new cab because it was a 1987, and lacked the provisions for the dash mounted wiper switch, and I wanted to use my original steering column. While taking out the 87 harness, I noticed a pigtail that comes thru the firewall on the passenger side that appears to run to the A/C box. I simply unhooked it from the main harness under the dash.
I figured the older cab harness I had would connect right up to the hvac harness, but the connectors are different. I only want to run the blower motor, as I don't plan on ever installing A/C. I'll look over the schematics you posted up and give it a go at making everything work.
You've been a huge help so far, thank you!
Gmachinz: Thanks for the offer. I'll try and get what I have working first before buying a new harness.
