My TB had a handsfree device installed years ago and needless to say it is way out of date so I removed it and found that the installer had drilled a hole in the stock dash plug where the 4x4 switch would be if it was 4 wheel drive. I was unable to find another dash plug anywhere on the net so I opted to buy a 4x4 switch that plugs into the hole for only 10 bucks. The switch arrived and the wires on the back were cut off with the harness still connected so I was wondering if there is a way to wire it so the lights on the 4x4 switch turn on with the interior lights. Does anyone know what colors control which on the harness? There are at least 20 different wires

brown with white stripe is 12v + for illumination and black wire is ground

just run an extra piece of wire to your rear wiper illumination wire (same color) and your black wire to a bolt behind the dash
