I have separate wires for the lamps needed at the rear of my truck. you should have a brake wire to the rear of the truck along w/ a left and right wire and taillamp wire. if you want to run a good (scraped metal frame) ground wire also. that's 5
get and learn how to use a simple VOM, volt ohm meter. disconnect everything first & trace your wires and make sure they are good, have continuity to the brake switch, both turn signals, the ground is good and the taillamp goes to the light switch and it's good. check the operation of your turn signal on the ohms scale.
once you know that, wire up the rear,
taillamps, brakes & left/right
make sure inside your housings that none of the wires are open, pinched, grounded or shorted to any other lamp.
It's a step by step process prove it all good first. build the path, check the ends.
Draw up on a sheet of binder paper the wires as you have them, colors etc & file it away when done.
If as stu says you use your brake lamp wire(s) as turn signals, ... that probably has to be a separate circuit within the turn lamp signal controller. unless the brake bulb is a dual filiment/ tail.
