My tail light basically turns on and off as it pleases.

If you need to remove the tail lite, brake lite and signal light harness start by removing the seat. Then disconnect the negative battery cable. Then detach the rear electrical harness connector. Then locate and follow the wires for the taillight and signal lights to the connector (8 pin) under the seat area and separate the connector. Then cut the cable tie strap holding the wiring harness to the frame and pull the harness through the fender opening. Then follow the conduit/harness back to the fender hole where the wiring exits the fender underside and enters the tail lite housing and backplate. This is not necessary for removal of the tail/brake lite assembly or the signal lie assemblies.

If you want to remove the tail/brake lite assembly remove the tail light lens and the with a small screwdriver depress the small tang in the tail lite four wire Multilock connector and remove the tail lite and then do the same and release the two wire signal light connectors one at a time from the tail lite base and remove the signal light connectors. These smaller two wire Multilock connectors are on the left and right sides of the base plate in the centre portions of the base plate where the 4 wire tail lite connector on the left side of the base plate is located and the wiring harness connector of the wires from the front of the bike to the base plate on the right side. The wires from the left and right signal lite assemblies go from these connection points on the base plate out through each side of the base plate and into the area under the back of the rear fender to each signal lite assembly. Then similarly release the Multilock connector of the harness from under the seat to the tail lite base. When you have disconnected the connectors from the base plate and have routed the wire harnesses out into the area under the fender you can release them from the wire clips at each side of the under fender areas. Then for each side remove the lamp support by unscrewing and removing the fastener and washer inside the rear fender, after which the lamp housing can be removed from the lamp support by pulling it and the wiring you disconnected from the tail lite base out through the lamp support. If you wish to release/remove the tail lite base undo the fastener and remove it.

Front or rear signals and brake??

Here is rear lighting for a start. Post a comment if you need front.

2002 DYNA ALL incl FXDWG

Connector 7 is under the seat. It is the main harness to tail lite connector. The wires from main connector are:
2002 All DOM and INT Including FXDWG

Connector 7 pin 1 goes to tail lite 94 connector pin 2 = BW

pin 2 goes to 94 pin 1 = O/W

pin 3 goes to 94 pin 5 = V

pin 4 goes nowhere = empty

pin 5 goes to 94 pin 6 = BK

pin 6 goes to 94 pin 4 = R/Y

pin 7 goes to 94 pin 3 = BE
pin 8 goes nowhere = empty

Connectors 93, 94, 18, 19 are all in the tail lite assembly.
19 = Rt Turn pin 1 = V/BN pin 2 = BK
18 = Lt Turn pin 1 = V/BN pin 2 = BK

93 = Brake and running lites pin 1 = BE = Dom running pin 2 = O/W = HDI running pin 3 = R/Y = Brake pin 4 = BK = ground

2008 TOURING is the same as 2002 DYNA and also has connector 45 in tail lite assembly where pin 1 = BK; pin 2 = Empty; Pin 3 = BK = licence plate lamp


Horn has 2 wires BK = ground going to main harness and Y/BK going to pin 6 of connector [2A] which is Main to interconnect harness 12-place Molex (gray) Inner fairing - leftt radio support bracket


You need What brake system front or rear??

Front signals from [31] pin one = BK = RT turn; pin 2 = BN = Rt Turn; pin 3 = BE = DOM running lite; pin 4 = BE = DOM running lite; pin 5 = V = Lt turn; pin 6 = BK = LT turn

[32] = pin one = BK; pin 2 = O/W = DOM Front Fender Tip Lite

[73] = 1 = GY/BK = Rt Aux lamp gnd; pin 2 = GY/BK = Lt Aux lamp Grnd

check for a bad ground wire for the tail lights. You are looking for a black ground wire near the bottom of the left rear corner of the car, inside. you may need to take the trim panel off to find it. if you take out the left tail light you should be able to follow the harness to where the black wires come out and a terminal is screwed to the body. turn on the hazard lights and when you get near the problem the lights will brighten and dim.

test lite the bulb, sounds like the bulb iz bad mebe,do u have trailer lites hooked up to tail lites? could be the wire harness. let me know.

Oh boy, Chevy uses 3 important wires to make up their tail light harness. Brown is used for your parking lights and yellow and green are your signal and brake light wires, yellow one side, green the other. You have some seriously crossed wires. Start with tracing the lic plate lite since that works. Make sure it leads into your main parking lights and the ground wires from these tail lites aren't cut. The lic place lite will work with just power because the body of the lite is grounded with the bumper. Then make sure that there is power to the signal wires. You can do this with a test light and the signal light switched on. You don't need anyone to step on the brakes since it's the same signal, only interepted. Most importantly, Remove the tail lites and check grounds!! Good luck
