trailer light fuses on 04 prerunner v6 xtracab

Hi everybody.. i joined just a moment ago. Found the site when i searched the above topic online..i bought a trailer to do side jobs, all the truck lights work fine.. trailer lights do not. It has a factory installed tow package. im assuming its the power fuse for the trailer, but i just dont know wtf it is.. can anyone help? even if ya cant help and just wanna bust my balls, thats fine too.. but id prefer the help.

 

Are you sure it's a factory "tow package"? Do you have a 4 pin or a 7 pin connector?

As far as I'm aware, the first gen tacomas never came with a factory 7 pin tow package. Some came with a bigger fan/radiator, and a hitch, iirc. Imo, a "tow package should have a brake controller, and power, too). Most of the "tow packages" I've seen are basically just a hitch and a 4 pin connector.

Are you talking about the trailer's running/side marker lights? Those are powered by the truck's running lights, and aren't independently fused. The only thing that's fused independently is the power wire on a 7 pin connector.

 

Hitch and 4 pin connector.. none of the trailer lights come on. At all. First time I’ve tried to use it, tbh. If I have to run the wiring, fine, but it just seems odd that I would have to.

 

I'm betting the converter box is bad. Pretty common issue.

 

Are you getting voltage at the plug pins? If not, trace the wires until you do get voltage. If you have voltage at the plug, you probably just have a dirty plug/bad connection. Clean it and put some dielectric lube in there. You might also have a bad ground either on the plug harness or the trailer itself.

This is basically what I have, so if all else fails, this is a super easy install...

This might even be what you have now.
