Hello... New to Forum. Please forgive.

[EZ Burris]

I have an older TT1 that I'm wanting to hardwire into my car. I have an old car charging unit that I've cut the cigarette lighter plug-in off and now what to directly wire the TT end into my 12v system. I have three wires, Red - Black - White. What wire is positive? What wire is ground? Can this be done and eliminate the cigarette plug-in?
Thanking you in advance... EZ

canderson will most likely give you the correct information.
In the meantime, bear in mind that the CLA outputs 5V.
Shooting 14V+ into your device may be not very beneficial.

Why don't you wire in a new socket behind the dash and leave your TomTom plugged in there.
