Trailer-plug wire Color Code

[heslinhotel]

Just bought 74 26' Argosy, trouble is it is iced in at the top of a very long(1/2mi) steep driveway with a switchback half way up. Seller is going to call me when the drive thaws.



I will have to travel on short notice and want to be as prepared as possible. It is a 4 1/2 hr drive one way and I might have to re-wire old plug or install new plug. As long as I get the brakes and their lights to work I stand a chance of doing a round trip in a single day. Does anyone know if 1974 used a round pin plug or a 7 pin modern day plug? Also looking for trailer color code for connector(female) end. Thanks

Sorry I can't help to answer your wiring question but I do read that some people bring temporary lighting with them to pick up trailers. Might be something to look into in case you are not able to get your questions answered.

The original plug would be a 7-pin (6 flat connectors arrayed around a center round pin), the common one you find now. If it's set up as original, it won't match the pin-out of a modern TV. Has it been sitting since the 70s, or towed recently with a modern vehicle? One of mine needed to be rewired when I got it, the other two (incl. a parts trailer) had already been updated.

I also had a problem with another Agosy I had years ago. Sadly did not keep my records or pic's. My main question is the large blue wire the brake wire?
I guess I could test at brake-a-way switch till I got a reading as long as the AS battery is not connected.
I already bought a new 7 pin and a 7 pin to 6 round pin converter, plus 6' piece of 7 strand wire in hopes I can put together onsite.

This may be of some help.

The factory original connect had 7 round pins.

The name on the connector was "Signal Stat".

The colors and each circuit is as follows.

White = ground
Black = Back up
Red = Left turn/ brake light
Brown = right turn/ brake lights
Yellow = Brakes
Blue = Charge line
Green = Clearance lights/ tail lights

My 1979 Safari was not originally wired the same as the current standard. But it was rewired to the current standard before our purchase

Thanks so much Andy, I think I'll just plan on putting modern 7 pin on right away.
