You're heading down a difficult path. You should avoid any custom wiring at all costs. Your harness should have the appropriate connectors. You should definitely not put the compressor on a direct, manual switch. It will freeze up the evaporator if it's not connected to the thermoswitch on the core.

Do you have a wiring diagram?

Im backing out of this thread. I've owned maybe 1 pup with air and it didnt work, so I'll leave the rest of the discussion to those who have more experience. I drove my non-ac pup for about 20yrs and survived
Good luck.

Ok Jack I will follow your advise. I will keep looking for the right part. No I don't have the wiring diagram. Can you please tell me where I can get it?

Thanks for your help!!!
