Hi, I bought a 2003 Ford f150 four wheel drive pu. I took the bed off and put on a stake bed. In the process of taking the bed off, I screwed up the tail light, brake light and blinker light wires. I have called Fords and they tell me the wiring harness for those functions is obsolete. What do I do now.? Can I find out what colors go to what lights at the connection on the frame near the back wheel. ? Any other suggestions will be Very much appreciated. thanks again.

 

Not much help here other than using a test light??
