New harness

[cdwood388]

I got my reworked harness today from speartech. I have a few questions. I have the key hot and the constant hot. Do I splice those in with the existing ones so that it all functions the same or what? How do i get the new air conditioning electronics to work with my old air conditioning system?

Need a lot more info to answer your A/C questions. Like...what vehicle, what type A/C dash control(request) do you have, what compressor, what does the rest of your system consist of, what are the labeled wires for the A/C, that Speartech provided, etc. As far as the constant 12 volt versus the keyed 12 volt question goes... No, they should not be simply connected together. They each need they're own separate source of 12 volt(keyed or not keyed)power for a reason. Fused, of course.
