2008 T660 Trailer brake lights don't work

No problem

 

Any update? I have no trailer lights but signal and 4 ways work and brake lights when i press them, i have a 2013 t660

 

When you flip the "P" switch on your dash your tail lights should come on the truck and trailer.

When you switch the headlight switch, the headlights and taillights should come on.

When you flip the marker switch switch your roof top clearance lights and the side marker lights on the trailer should come on. Your taillights and headlights will stay off unless you flip one of those switches.

If you have no tail lights on your trailer, check the fuse, if the fuse is good, swap the relay with another one.

 

Tried that also, both fuses are good and relays and pigtail is good. Not sure what it is

 

If you're getting power at the pigtail then it's a trailer issue.

Most likely the wires have corroded on the back side of the "phillips" connector.

 

All my lights work on my truck.All the running lights work on the truck and trailer.My pigtail is good.Fuses are good.The problem is .I have no 4 ways and turn signals on the trailer.Any ideas have to solve this issue? I have a 13 t660 thanks

 

Do the turn signals work at the pigtail?

 

No

 

Unscrew that connector and check the pins there. That connector is the opposite end of your pigtail. Find the pins that correlate to the yellow and green wires on that connector (left/right turn) and check the little pins.

 

Ok bet will do it now.But would both sides come out at the same time?
