Abs light

Ok, first you need to check your abs fuses and relays to remedy the no power to center prong. Second, you have a short between your left and right turn signals and your center prong. You drive a volvo so I can't really help you with your wiring harness, but that basically what's going on with your truck right now.

Most likely what happen was that your turn signals shorted out the abs center prong and blew it's fuse or tripped it's circuit breaker.

On my t660, all of the trailer wiring (turn, brake, marker, tail, abs, ground) all are contained in one pig tail that runs from the firewall, under the truck back to the rear of the sleeper. There's no bundle of individual wires to check so the only place the pigtail would have an issue is right at the firewall or where the pigtail plugs into the connector that's located behind the sleeper.

A quick check of where the female end of the pigtail connects to the connector behind the sleeper (not the pigtail that goes from truck to trailer, but the one that goes from the firewall to the back of the sleeper) would be easy.

Checking the fuses, relays, and wires on the firewall might be a little more difficult. But I've never seen how a volvo is wired up so I could be wrong.

But you're definitely looking for a blown fuse, and a short between the blue, yellow, and green wires (blue=abs, yellow=r turn, green=light turn).
Check your center prong with either your left or right turn signal on and you'll know just exactly which one is shorted over to your center prong abs.

Sorry, I was sleep.

 

No biggie. Just make sure ti find the short or it'll keep happening.
