On my trailer connector i have a 'line of fire' led strip and when i brake and use my left blinker it doesnt work. The strip isn't bad cuz i checked it on my friends truck. I cant figure out which wire goes to the left blinker/ brake before the yellow wire that goes into the trailer connector. Any help would be great, i use my truck everyday for towing boats and already have a 5-day tag for a bad light on my truck.

 

is it a factory harness? check fuse 3 or 7, i forget which

 

Maybe the line of fire is low on blinker fluid? I've heard those LEDs go through the fluid faster......

 

well there is plenty of blinker fluid in the strip as well as brake fluid so i dont think thats the issue.

 

ok i will check that in the morning and let you know if that fixed anything.

 

Check to make sure the ground is good on the led strip. Also make sure the polarity is correct. My led strips have diodes in them and will not work if the polarity is reversed.

 

'VW TANK' was correct; fuse number 7 was missing! IDK how it went missing but all i know is that it works now. Thanks Dan
