Standard wiring for trailor plugs

[Ax-man]

I was rewiring our stump grinder lights to a different truck yesterday.

I have heard their is a standard wiring for a 6 or 7 pole plug. Anyone have a picture they could put up. I might get ambitious some day and rewire all the trucks, trailors so that it doesn't matter which truck pulls what trailor they are all on the same wiring for the lights.

Axman, I did a Google search "standard trailer wiring diagram" and turned up lots of them It sure is handy to have the industry standard. Saves blown fuses and incorrect working lights which could be worse than none.

If you go and purchase a 6-7 Pole plug or receptacle The standard diagram will be with it. Hmmmmmm Wiring you trailer brakes to your vehicles Blinker might be interesting.

FYI, there seems to be TWO "standard" wiring systems in place.

Just ask Newfie. =)

hmmm, yup, one that works on my trucks and one that smokes my chipper brakes behind your trucks.

But Mike; here's what's so freaky...

Your chipper and your equipment trailer both work fine behind your truck.

However... your equip trailer works fine behind my truck, but your chipper doesn't... WTF??

Beats the $h!t outta me. Wires make my head hurt so someone else did all my wiring. Or maybe you smoked the brakes on the equipment trailer too.

Everything around here seems to be the six-round. Now when we get something that uses a different system, we re-wire it immediately.

I have made up an adapter that will take any trailer light plug to another. Now I see you can buy them. Uneversal trailer adapter.
You can get some weird feedback problems if the ground connection thru the connectors is faulty. Ground for lights may flow thru the ball or safety chains and give lights ok or might start feeding back thru the brake circuit. A friend recently had apparent electronic transmission problems and had a quote of 2500 bucks. Turned out it was a body to frame ground problem on the truck, coupled to trailer brakes grounded to body not frame. It can make your puzzler sore for sure. Been there!

The adapters can be $10-25 a piece...and if you don't have the right one, you're outta luck.

The one adapter should get you going for lights on any combination of the standard three plugs and receptacles (providing they are standard of course) Get you out of a pinch but too bulky and trouble prone for steady usage.
Fill every connection with white grease to keep the green corrosion away. I hates fiddling with now and then lights especially in winter.
