I put a 12v in my 03 Dodge 3500, ive got everything working but the a/c. Im using the 12v A/C compressor and My 03 wiring harness. I cut the plug of my 12v wiring harness and put it on my 03 wiring harness where it would plug into my 12v a/c compressor. The a/c compressor will not come on unless you jump the relay which it will then come on but not cycle. I know there are some people who have done these conversions and got the a/c working. Open to any suggestions. Thanks
