Hello,

for the car charger plug, on a 2007 s2000, the two wires in the back of the plug area, which one is the positive and which one is the negative?

I need the wire color for the 12 volt accessories behind the cigarette lighter plug and the grond.

trying to hardwire my navi charger to it.

please help.

thank you in advance.

 

anybody?

 

in an AP1 (and I have no reason to believe an AP2 would be different)
white/red = +
black = ground
however, a better place to hardwire is the underdash fuse box:

Option Connector E - live when the parking lights are on, through fuse 23, 10 amps
Option Connector D - live always, through fuse 42, 40 amps
Option Connector C - live when ignition on (and not cranking) through fuse 42, 40 amps.
All 3 of these connectors are recessed male 1/4" quick-connects, and yes, you should use an in-line fuse, especially when connecting to D or C.

(from the technical FAQ)

 

i need to add one too. Also, you can use a light tester to figure out which is - or +.
