How to fix Crusie control not working when installing LED's tail lights.

So as seen in the General Section I installed LED taillights and all was good until I tried to use my cruise control at night. In fact today it did not work at all with the lights on or off. So here is the fix.

These are the LED tail lights I purchased http://r.ebay.com/7Qo6og

This happens with a lot of cheap tail lights there is not resistance figured in when they build them so most systems see a burnt out light or like this something does not work that has to deal with the brake or running lights.

Soooo the fix is load resisters, got a pair at AutoZone for $12.99. You can get these at electronic shops also you need 10 ohm 25 watt load resisters. My favorite electronic shop was out, so next more expensive was AutoZone.

These will be installed between the ground which is the Black wire and the Blue wire which is the positive switched by the brake pedal. Both sides need to be done and both sides they are the outside wires. Make sure you are dealing with the connector that has the 3 wires not the 2 wires. 3 wires is the brake light connection.

These get hot like a 25 watt light bulb so you want to make sure the resister is 1" away from other wires. It may not melt them but it may char them from heat over time causing them to break.

Here they are connected with the splicer connections.

I will redo these later and use high temp silicone and extend the wires so I can mount them to the metal pocket the light sits in. I did this as a test as I was unsure if this was going to be the fix.

So now my cruise control works and the LED light still work and are bright as they where before.

Was this an issue for everyone with these tail lights? I heard other people only had problems if they had a barn door model

Mine is a lift Gate and YukonXL04 has a barn door both did the same thing. So I don't think its rear door specific.

I can also say with certainty now the this will apply to all the 2000-2006 Chevy/GMC Yukon/Tahoe/Suburban. I just installed these in my sisters' 05 Tahoe and same deal. Had to install the load resisters or the cruise control would not work if the headlights where on.

I installed LED tail lights in my 04 tahoe recently and lost CC. I installed 2 50w 6ohm resistors on each side. Connecting to the black and the blue wire. My cruise control still does not work. I swapped back to the original tails and the cruise control started working again. Is there something I am missing?? Any help would be great

The instructions said quote: "You can get these at electronic shops also you need 10 ohm 25 watt load resisters". Not 6 ohm 50 watt. It's the resistance that matters most. The wattage is the amount of power they will handle. So 50 watt is OK but 6 ohms isn't enough resistance, you need 10 ohms..

I found some 10ohm and installed according to the first post and still do not have cruise control. Any other ideas on what could be going on?
