Default Need some wiring help
Installed a tombstone taillight from J&P and am having the following problem:
When ground is connected, all lights work except brake light.
With ground not connected, all lights work except tail light.
Any advice will be much appreciated.
Bike is a 2004 Road King deluxe.
Thanks, Ken Adams

Did you have to splice wire it, or did it connect into an existing harness?

A call to J&P tech assist line is in order.Plug and play is the only way to go.

Three wires, green, red, black. Red = brake, Green = run, Black = ground.
If that doesn't work, check the socket, Made in China, Charley could have been color blind.

Ken,
Make sure the correct wires were hooked to the new Tombstone wires. On your 04 Road King R/Y is the brake, BE is running light, BN right turn, V left turn and BK is ground.

Those generic aftermarket tombstones didn't use a ground wire unless you rigged one they relied on frame grounding when you install it, the 2 wires coming out of the socket are just for the hi/lo on the bulb , low being taillight hi being brakes.

Sure sounds like a ground wire mix up.

Some do have a ground depends on the one he got. Look at step 7
