Trailer Plug Wiring?

[cavy16262]

I have to change the plug on the trailer. Sooooo, I get a new one, have my wiring diagram of standard wiring and "wah-lah" the color code doesn't make sense with the 'standard'!!



Any comments?





White - Ground

I have Black - heavy for 12V in the trailer (as tested by my inside 12V lights and the hitch light during testing).



Red - Left Turn Signal

Brown - Right Turn Signal

Blue - Brakes?

Green - Clearance

Yellow - Nothing but in wiring diagram it shows "backup" light.

You could use a continuity tester to check the plug positions on the old plug (back to thee junction box) and then transfer the plug pin in the new connectore. I would also leave a sheet with the new color code in the junction box for the future.

The list you have posted is correct for a standard 7 way plug connection. The black is a direct line to the trailer batteries for charging, and yes the blue is the brakes. The yellow will not be used if your trailer doesn't have backup lights. (mine doesn't)

I think on the Chevy, It shows you on the outlet on the back of the truck what every thing is. This is as I recall.

On my Ford F2507 pin plug, it is written on the truck plug out side door what each feed is.

Found this digging around the internet. Pretty clear cut. Note: Some accessories are wired for reverse light. (center connector)

Ah yes! You were all correct. I did find the wiring schematic on the truck plug and matched it up to the "continuity tested" trailer wires....Don't forget to disconnect the battery so when you have all those wires bared and they start touching each other...you don't get the back feed...My Bad!

Thanks and I'm up and running "lites" again.
