Trailer Lights Gurus--Got a Question.

[npalen]

Take a break and start again tomorrow. Start from the top and make sure the trailer lights still work, then double check that adapter ground where it connects to your truck. Personally, still betting on the tralier light adapter kit you installed years ago being faulty, or at least dirty connections on it.

Take that break. You're going in circles at this point.

Good advice. Will do.

Why would the trailer brake actuators be on the vehicle? What good would that do after the trailer leaves the hitch and tears off the wiring?

The controller is on the vehicle and a rudimentary receiver on the trailer to apply the proper pressure to the brake actuators whether they be electric, hydraulic, or pneumatic.

Actuator is on truck.... Breakaway battery and activation switch is on trailer.... Small tether to a pull pin comes out of switch and locks up trailer breaks... DOT and State law says in trailers over 1500 pounds it has have breakaway and to be able to hold trailer brakes lock for at least 20 minutes...

How the Trailer Break-away System Works

Excuse me but my electric brakes are powered directly from proportional controller under dash to magnets (actuator) on backing plates of trailer axles, the is no rudimentary receiver in electrical brake system... Yes there is some hydraulic serge system on trailers but they don't have any controls from operator cab..... Have not seem any pneumatic brakes on pick up level trucks (mainly reserved for LRGE trucks)...

I give up! After installing the fuse and finding the connections worked on the trailer connector as described in post #38 above with the pickup lights off, I hooked the trailer up and now find that none of the trailer light functions are working with or without the fuse and with or without the pickup lights on! Go figure.

Edit: So I go out now and did some more troubleshooting and find that the fuse I plugged in was in an inactive port BUT now I have all light functions working on the trailer connector again even with lights OFF.

I'm thinking there is a bad and intermittent connection somewhere in the pickup aftermarket trailer harness. Will pull the harness in the morning and clean all the connections as someone suggested above..

Might investigate whether there is factory harness on board but not connected..... All truck wiring may be in place but just no 4 pin or 7 pin connector on rear.... Climb under truck and find where wire harness goes from front to rear of truck and follow it back, look for a Plug/Socket with 4 to 7 wires on it that is not connected to anything.....

Something like this may be solution to stock truck wiring...

Trolling might be an understatment. I think more accurate to ask "are you intentionally makeing yourself out as a fool or are you actually clueless and don't know how to admit it?"

No not trolling. Reminding myself why anger management said I had to participate.

I find your ignorance refreshing and productive.

What!? Anger management says you have to participate? Does this work for alcoholism too?! -- we have to drink?!?! WoooooooHooooooo!!!!!

Pretty tough statement for someone who has been pretty much wrong all the way along....

My 57 sure doesn't, not even a switch for hazards.

Who leaves their vehicle to go get a flat repaired??? I put on the spare and drive the flat to the shop.

We drove out to Oklahoma and back last weekend. I'd guess we saw at least 20 cars/pickups/suvs/small trailers laying on the side of the road with one tire missing and no one around.

However, I don't recall any of them having their flashers on.

You know, guys, the trailer brake actuator is not on the truck. The trailer brake controller is on the truck. The thing that actuates the brakes is on the trailer. If it wasn't, the trailer would have no brakes if it broke away.

The magnet in the brake assembly controls the actuator arm in the brake that applies pressure to the shoes that grab the drum. It gets the voltage from the brake controller in the cab. Brake controller, not actuator. Controller.

Show me where I am wrong with proof and while your at it, tell me which of these you install in your vehicles under the dash:

Not a tough statement; I truly think you are an ignorant kid, sure you have lots of knowledge and are helpful, however your attitude diminishes that a lot.
