bigger battery and beefier wiring

 

You need to add a load resistor to your tail lights, then everything will work fine.

I'm not sure of the size load resistor, but that what you need. If you do a search I'm
sure it's posted some where in the forums.

 

Thank you ! I will look up what size

 

I find this weird (and it could be a 4G thing, idk) but why is your taillights effecting your cruise control? Does it effect anything else?

 

Here it is: http://club4g.org/board/electronics...19394-how-install-load-resistors-led-tail-lights-get-rid-off-tcl-off-light.html

Aftermarket being aftermarket, they most likely don't use the same power or are wired in a stupid way. I've never gotten to open up the aftermarket tail lights, but LED's don't like you messing with their power. Light coming on & cruise control not working is probably a way for the car to say something's wrong.

 

Thanks for finding this How To for Jaime...


Seeings how the tail-lights and many other system fall under the CONTROLLER AREA NETWORK (CAN) system, the ECU monitors the resistance within the system. So when there is a resistance change the ECU precedes a problem in the electrical system and will shut down other components within the system to prevent damage to equipment. In the case of the tail-lights, other systems that can be effected are the interior lighting, cruse control, side marker lighting, brake lights, and sometimes dash panel lighting. Any, or all of these system can be effected without a proper load on the tail-lights.

 

Thank you everyone its a big help!
