Im having problems with my LED Dome relay. 1st off it seems I can never get it out of program mode or parade mode. I would just like to have "normal" dome light opposition. Anyone know how to do that?
2nd thing is have found is back feeding through the dome lights when I push the breaks "sometimes". Is it possible I have a bad diod in my wiring harness?

Put one of those resistors I sent with the unit over the dome light power and ground.
Boy I don't know if I have them, I'll look in my box of stuff. What size resistor do I need? (what color bands?) do go from black to purple or black to purple/white?
Is there a way to bypass the program for parade mode?

It's a 49.9 Kohm 1/8 watt part I sent with the units but most anything at or less than that resistance will work. You can test if it will fix the problem by installing the incandesent bulb. If that fixes it, the resistor should fix it with LEDs.
PM me your address and I will send you some if you can't find one localy.
Can I take the relay out and still have lights work? I re-wired the relay socket when I in stalled the new LED on, I'd like to convert back but still use LEDs.
The problem is the led relay does not keep its program. I'll get it set to car show mode then in a few days it will blink nonstop. Reprogram it back then it does it again.
The dome light back feeding, I never noticed it before with bulbs in only LEDs. I have the new DMCH domlight housings.

I think the resistor may cure your problem. I had to add one resistor when I changed from incandesent dome light to LEDs. I had similar problem of not exiting program mode and random entering of program mode.
I think you can remove the unit and jumper two pins to get back to stock but I have not tested it yet.
The resistor (wired over the two LED lugs) just puts a very small load (only when the LED is on) on the signal I monitor. It all depends on how your LED is constructed, LED voltage, how many in a string as to if it will work without the resistor.

Dave - I have also noticed that the car will occasionally go into programming mode for no reason. I haven't installed any of the resistors you sent. I am also slightly annoyed by the dim glow from the red rear lamps in the door, so I had been planning to tackle the resistors anyway. So you think installing them will help with the random programming glitch too?
Do you have any pictures of how you installed the resistor? I don't quite get the intended config from your guide. Do I need one per lamp or just one per door?

Mine is a non-standard dome light but all you need to do is connect the resistor on the terminals that go to the two LED pins. The same goes for one door light to eliminate the faint glow when it goes into battery save mode. You would need to do one door light in each door. Adding to the door light, just pull one housing out and strip a little insulation off the two wires, wrap the resistor wire to each light wire, solder it and tape over it to keep it insulated. The dome light you can solder it so it will not interfere with the switch action of the dome light.
I'm 95% sure the dome light resistor will cure your problems.

Very cool. One or both dome lights? Any action required on the trunk/engine bay courtesy lights?
