Need Trailer Wiring Help

I have a 2000 XJ Classic that I am adding trailer wiring to. I have the factory 7 pin connector and I don't know what wires are for what. This is what I have and what I believe they are:

Blue - Electric Brakes
Black - Ground
Red - Aux. Power
Yellow - ?
Green - ?
Brown w/Green Tracer - ?
Brown w/Yellow Tracer - ?

I know that these are for trailer lights, but which is for left/right brake lights or for running lights? For now I just want to get at least the main four pins working meaning I don't need brakes, aux power or reverse lights working right now.

If anyone knows what wires correspond to what functions, it would be greatly appreciated. Thank you in advance.

typically yellow is left,green is right,and brn is marker/tail lights,some chrysler products used a seperate wire for brake and turn I dont recall if they did on jeep,however turn your key on and test the wires for function with a test light that will tell you,sounds to me like the brn with tracers are left and right marker lights but cant be 100% sure.when testing if your turn and brake are the same wire then left and right wire will light when brake applied and when a turn function si selected then it will flash and the other will remain solid,

The electrical FSM has the pin-outs. On my 91, the wires mate up to standard hitch connectors as follows:

Jeep -- function -- hitch plug
==================================
Red -- aux power (battery) -- Black
Tan -- right turn -- Green
Blue -- electric brakes -- Blue
Black -- system ground -- White
Green -- left turn -- Yellow
Brn/Red -- tail lights -- Brown
Brn/Grn -- reverse lights -- Purple

Get a 12v bulb and test the signals and whatnot
