led tail light wiring

Is there any way to wire up the old style fbi led lights without the TAC module or is there a module I can get for less....these led lights only have two wires on them a positive and a ground. Thanks for the help in advance.

there is a very easy way to do this...you use a common relay one on each light. you put the 12v for the parking lights through the coil side of the relay and put the 12v for the turn and brake lamps on the lamp side of the relay coil...basicly you use the coil to use up a slight bit of voltage to dim the lights....

do you know the numbers on the relay for the wiring like 87,86,85,30 which wire goes where. Or maybe a drawing....thanks for the info. Also does this work if you have seperate brake and turn signal wires.

bump....can someone please explain this to me or draw it out to me it doesnt make much sense but maybe I am over thinking it.

ok put your parking light wire to the 85 poll and the power for the led and the brake lamp turn signal to the 86.. put the grounds togeather.

leave the others empty, also how will it seperate my brake lights from my turn signal they are seperate now.If I wire them together and my foot is on the brake and I turn on my signal it would not flash. You get what Im saying

i used a 3-1 trailer wiring converter. you can get it at any truck or trailer accessory shop

yes leave the others empty.....i only have tried this on a gm turn signal switch were the brake signal goes through the turn signal cir. if you have seprate brake and turn than the turn would stop flashing
