Default Tail light problem with LED License Plate Holder

Installing the Softbrake tag relo kit, using Custom Dynamics LED tag frame. I spliced the white tag frame wire into the existing tag illumination wire (grey) and spliced the black tag frame wire into the existing ground wire. Used butt crimps for both (checked them, and could not pull the wires out of the crimp while pulling hard).

So now, my brake light works, but the running light does not. And the existing tag light does not work nor does the new LED light. All other lights (including blinkers) work. I replaced my existing tag light bulb (old one looked burned out) thinking it needed to be present to complete that circuit, but the new light didnt work.

My question, if my ground connection is bad, could my brake light still work while my running light doesnt (same bulb, 2 filaments)?

Thanks

What year is your bike? When I did radiantz LED plate frame, I called the dealer to ask what was the hot wire, and they said blue. Mine's 2010 FLSTC

I have a 2007 FLSTN. I'm using a Custom Dynamics LED plate, which has a white wire, and a black. According to the instructions, white is hot, black is ground.

Right, to be clear, the wire on the *bike* is blue (at least mine is), so I'm saying connect white to blue.

As far as ground, I didn't splice to a ground wire, I found a bolt inside the light that I connected it to.

I spliced the white wire (hot from tag frame) into my existing tag light wire (grey). The existing tag light wire (on bike) is the only wire going to the tag light, so I would assume its hot?

I'm gonna try the hot wire going to the running/brake light. Thanks for your help.

Just did the same install last week. Used the same color wires you mention. Spliced into the gray and i just soldered the black to the ground wire connector.
I'd disconnect the tag light and verify everything works normally. You could try touching the white and black wire to a battery just to verify it lights up correctly. Either tag led is bad or your connections aren't making good contact.

Thanks. I'm hoping its just bad connections. I'm going to solder/heat shrink the connections instead of butt crimps. It just seemed odd my brake light worked but running light didnt.

Well, turns out it was a fuse. I thought all the lights were on one fuse, but they're not.

I'm splicing the white LED tag light wire (hot) to the grey bike tag light wire (as the instructions say to), and its blowing the fuse (15amp). I'll call Custom Dynamics tomorrow. Any ideas why it would blow the fuse??
