Hey guys i need some help. i just recently bought a new LED Light Bar and it has white LEDs for the reverse light. except i cant get them to work...im trying to hard wire them intot he reverse lights in my tail lights but cant get them to work...help!

 

If you're trying to go right into one of your rear lights the reverse lights have a 2-wire connector. Backup lamp is lt. green & black ground. Look for a ziptied harness on the crossmember underneath the rear of the truck. If you have the trailer wiring harness it'd be easier.

 

ok well to wire the brake, R and L turn, and running lights i used the trailer wiring harness. so i used 4 out of the 6 wires. there were 2 wires left over but the directions didnt say to use them.

 

Well, if you have the light green there use it. If the leftover is a dark blue it's there in case you wanted to run electric brakes back there someday.

 

ok ill check out which wire is left over

 

since when did these Blazer's come pre-wired for an electric brake controller?

 

For the 2nd gens, if you had the tow package, you were pre-wired for a brake controller and 8-pin trailer plug.

 

really? my truck has the factory tow package on it, but i just ran my own wiring since i never knew there was any already there.

where is the wiring under the dash? specifically the thick dk blue for the rear feed?

good to know for the future S series i'll more than likely end up buying.

 

I dunno about "thick". Depending on what you're hooking up I have a feeling you did a good thing running your own wiring. To be honest I've never taken my own harness apart to look at it, I just splice a new 4 wire plug on every two years it seems.

 

yeah, i run a 7-pin plug, and always take it apart every Spring to inspect for salt damage. Ontario lives on a high diet of salt for the Winter-too many damn idiots on the road to use just sand like out West. i know our weather in Ontario isn't nearly as cold as out West, but it sure would be nie to not have white stains on the carpet/floor mats all the time.
