Just tap the yellow into the brake light wire. I'm pretty sure the gray wire is for BMW CANBUS systems and is not needed. I did not use a gray wire when I installed both of my coocase cases on my DL>
I need help - running into similar problems as you.Thanks to all who responded. After trying every possible combination of wiring, nothing worked. I then checked the continuity of the yellow wire coming from the mounting plate, and nothing. I found what I thought was a slice a few inches in, under the plate, and figured it was bad, cut it out, hooked back up to the brake wire and now the brake lights work. Thought now for running lights all I need to do is splice back on a second wire and would be good to go. Before I did I opened the shrink wrap to inspect what I thought was the fractured splice only to find a resistor, and a second different one on the gray wire that should be used for the running lights. Continuity across both of them is no good. Could it be possible they are burned out?? and if so does anyone know what to replace them with. I'm afraid the LED's will burn out without them.
Some findings with a fresh 9V battery:I need help - running into similar problems as you.
I just go the EB Tail connector today, took apart tail and connected the EB connector.
The regular stock brake/running light still work so the connector is at least half working (the split connector is working).
When I connected the coocase unswitched wires (red/black) it also works - I can use the coocase remote control.
But the darn Coocase running/brake lights do not work.
I connected the yellow Coocase harness as instructed - the green goes to white (running lights) and blue goes to EB red (brake line). No lights on the coocase.
Should I tear open the coocase wires to find where a problem might be with the yellow?
What should be the voltage between the EB tail connectors line to ground (black) - 12V (12.6) volts?
Wasted 2 hours on that :headbang: (EDIT: and my multi meter was left running and died..waiting for 9V battery to charge)
Hansong - thanks for trying to help.BigMan,
I'm working with a Vee, not Wee, so I don't know about the wire colors in the tail you need to connect to.
What my problem ended up being was a bad diode that is in the yellow wire coming from the mounting plate. I originally thought it was a bad splice, but found a diode when I opened the shrinkwrap. I have no real knowledge of components such as diodes or resistors so I took it to a biomedical engineer at work who tested it for me. It was definitely bad. Replaced it with what he told me I needed. I'm waiting for the green/blue sub-harness from Twisted Throttle to hook up my running/brake lights, but i'pretty sure everything will work OK.
On the Vee, the running light wire taps into the gray (switched power) and the brake goes to the white with black stripe, same as my hyperlites.
