I need help with wiring a 6 pin square traler plug to my Chevy blazer which wires goes to which ones do I use all 6 or 4 please help thanks

 

White - ground
Yellow - left turn
Green - right turn
Brown - running lights
Blue - brakes?
Light green - backup lights?

 

Where are those 6 wires coming from? Your truck only provides 4 wires in the oem trailer wiring tucked up near the spare tire.

Disregard my last transmission, of all the things I have lost I miss my mind the most. I will assume that those are your vehicle wires. In order to give you the decode, we need the 6 pin square pinout or at least the item being towed. This is not a common trailer plug and appears to have more than one pinout. Tom's vehicle wiring is correct incl. the ? marked ones.

thank you it all worked

 

one set is off of plug I bought for my jayco pup. Which I switched with 4 pin and my blazr doesn't have 4 wires tucked under bumper it has 6 factory that's how many there, were I figured it out with you alls help

 

not on my oem it's 6 wires that were tucked and I have the manual that says and has 6 wires on my 2000 Chevy blazer not 4 but I only used 4 last 2 are light green light blue backup an auxillary lights or watever

 

Tom all my lights work now during the day well the lights work great and everything but when I turn my taillights on my 94 jayco pup and I hit the brakes or signal only when lights are on the light comes on but Barley you have to put your eye close to see the bulb like it's dimm an same thing for with signal but my blazer lights brakes signals are bright an normal

 

That sounds like a grounding problem. I would check where the white wire is connected to the trailer frame, and also where the lights themselves are grounded. You may have a poor connection that's good enough to complete the circuit, but drops voltage under higher loads.

 

OK Tom I will check that out with everything you said and see what the problem is... Thanks I'll update soon.
