wiring harnes/ lighting
 

i have just bought a 2005 taurus wagon sel with 3.0l vulcan engine and it has a trailer hitch but no wiring for it. it has seperate rear signal and brake/running lights! does any one were i can get a wiring kit which is plug and play so i dont have to cut wires, and all the info on the net say that usaully the singal and brake lights are together and the brake is seperate ! plus the utility trailer i was given has seperate brake/running lights and signals as well(two different people). also i would like to replace the factory headlight housings with projector style hid system and rear with led tail lights! but i cant find anybody who sells them. i do all my driving at night so i would love to see better than factory lighting? thanks for any help
