so i ordered some led taillights and installed them. so far everything was working good but i hadnt checked my cruise control and my auto start wouldnt work. (after a 4 hour roadtrip with no cruise). The taillights have black ballast boxes so is it possible the taillights are giving to much resistance? just wondering what i need to do since winters here are brutal

Hard to believe tail lights interfere with cruise control? Have you checked the fuses/relays? And leds use less resistance then stock so the black ballast probably just recreates the resistance of halogen bulbs
And by auto start you have a remote start?
And I guess a good diagnostic if the fuses check out is unplug the tail lights and try it out. (Put in the factory lights if it isn't too much effort)

I had all LED brake lights and side lights (not side markers) and lost cruise. Switched to regular bulbs and worked. Also I ran all the LEDs in the back except one and I think cruise worked since it had enough resistance from that one stock bulb.
The lights will still work but cruise wont. To me cruise>LED tail lights.
But I have LED reverse and turn signals with no problem. Just need two LED relays to make the turn signals/4 ways work
