well the battery wire needs a constant power or the memory will crap out everytime the keys turned off. If you have a test light handy I would find which wire in the harness is constant power and which one is acc power and go from there. You are right in that they both need to be hooked to 12 volts but they dont have to be hooked to the same 12 volts. You can tie one into the cig lighter if you need to.
If you agree that the answer I provided is correct please remember to "accept" and/or mark it as "helpful" so I know I'm doing a good job. Thank you, I would really appreciate it.
