Trailer lights not working completely, the truck came with the round light connector

[maachuu]

the one that has 6 blades around a center spot, I have tried 2 adapters and no luck yet. I just got one from Autozone that says its a 7 way to 4 or 5 pin adapter. My connector coming off the boat is a 5 pin. I get tail lights, trailer lights on the side of trailer but only the left side brake & turn signal works. The right side tail light works but no brake lights and no turn signal. Anybody got any idea where I need to start checking ? I have LED trailer lights, dont know if that will make a difference or not.

Here is the picture of the connector on the truck


here is the adapter that Autozone said I needed, if you notice it only has 4 blades in it



Here is the connector coming off of my trailer

Larry, check the fuses under the hood. Got seperate fuses for right and left.

Turn & brake lights work on the truck jig

You can also buy one of these testers for about $5. It plugs into your vehicle trailer plug and has leds on it for each light. Tells you right quick if the problem is in the vehicle for the trailer wiring, I'd check your fuse like JF said above, but if the fuse is blown your vehicle lights should not work either unless it has separate fuses for the trailer harness, mine does not.

Check em anyway. If fuses are good then you have broken wires from side not working.

The fuse box under the hood of your Z 71 has separate fuses for the trailer lights....check them.

Check to make sure you have GOOD GROUND from truck to trailer not just contact at ball hitch.

If you have a 5 pin connector coming off of the trailer (probably due to LED's), you probably gonna need a 5 pin connector on the truck side. I wouldn't think a 4 or 5 pin connector would work, unless it looks like this:

Bet it is the fuses, took me an hour to figure it out on Ree's truck.
