So my weekend project was to add a KBX grill and headlight surrounds while upgrading to LED marker/turn/brake lights (from Mud UK) to my 1991 LHD euro spec 200tdi Defender.
Grill was straight forward, one headlight surround needed a little trimming to fit, nothing crazy.
Before I started on the lights I searched the forum and read as many of the threads I could find on problems others have had as to try and avoid any of the same issues.
End result is I installed all of the lights, one by one. At each step I op checked every light to as to try and catch issues as they popped up versus at the end when it was too late to know where the problem came from.
Turn signals went in on the front and back with no issues. All worked all at all the appropriate times with no issues. I was unable to install the fender turn indicator lights as the set I received from Mud did not match the type I have on the truck. I'm assuming this is a model year issue that I didn't see when ordering. So those are still incandescent. But everything worked with the turn switch on the steering column and the hazard switch.
Left brake light installed and worked fine. All turn signals worked fine.
Right light I installed with out pre-checking the wires as I was on the last light and figured they would match as all the other ones had. Well I wire it up and screw it in and neither brake light works. I pull it back out, swap the two leads (leave the ground on black) and now both brake lights work perfect under all conditions. Even the third brake light that is bolted to the inside of the top of the rear door works as it did before.
BUT, now the rear passenger turn signal is not working.
I'm assuming everyone is going to say check my grounds. I added a fresh ground to the rear passenger turn signal and it did not remedy the situation. Before I start tearing things apart and trying to add new grounds does anyone have any advice?
The other symptoms that occurred with the last light going in are:
- The trailer light on the instrument cluster is constantly illuminated (it only illuminated momentarily at start up before)
- The fog light indicator on the instrument cluster illuminates (dimly) when the LEFT indicator is selected.
- The rear fog light is not illuminating when switched on (not that I care. If I can find a solution that results in this going a way, i don't mind)
Any advice is appreciated.
