I'm going to drop the beat up valance on the 88 b2 and incorporate them into either the bottom the core support or in aftermarket bumper. The real question is how is how do you hook up led turns. I read somewhere on google about some kind of different flasher that has a circuit board to run the amperage. Also ive seen 3wire and 2wire lights. which one do i choose. ill prob run either 2 1/2 or 3in lights just so you know

If you have a light housing that has a replaceable bulb, just put the bulb in the socket. If it doesn't work, remove the bulb, turn it 180 degrees, and put it back in. If you need to put a new housing in, be mindful of the polarity. LED lights are polarity sensitive, so don't reverse the positive and negative wires. Check operation before making final connections.

If you are running ONLY turn signals, the two wire is the one you need. That gives you a negative (ground) and a positive (circuit) wire.

If you are putting in running lights AND turn signals (3 wire), they share a common negative (ground) wire and each circuit has its' own positive (circuit) wire.

The LED lights are more efficient. That means they draw less current and waste less electricity through heat than "normal" bulbs. The flasher in most turn signal systems uses heated contacts to open and close the circuit (thermal flasher). Because the LEDs use less heat, the thermal flasher gets more heat pushed to it and will operate faster (blink faster). This will eventually burn the thermal flasher out. The thermal flasher will work for a short time with LED lights.

The correct (digital) flasher is made for LED lights and will blink correctly. It is a simple remove and replace plug in to the correct circuit. The LED (digital) flasher will work correctly for incandescent bulbs as well, so don't worry about mix and match in the circuit. Ask for an LED flasher for your year and model truck at the parts store. When you get the flasher, turn your turn signals on and follow the plink sound to the flasher. If you remove the flasher with the turn signals operating, they will stop flashing and go out. That is the flasher to replace.

if you co with LED turn signals you will need a new electronic flasher, I believe the B2 takes a EL12 for both the hazards and turn.

as for your question about 2 and 3 wires, you might be referring to trailer lights, so the color code to those is as followed.

2 wire = This light is just a marker light.
Ground is the white wire
Positive is the Black wire.

3 Wire = Marker light with Turn.
Ground is the black wire
Positive is the white wire
Turn /brake is the red wire
