Thread: 5 way flat trailer side plug

Amazon has the plug. You'll have the splice the wires.

There are other 5 ways on there too.

Right, I saw the 5 ways on there. If they only have 6 wires, would have to splice or combine to match the 10 wires coming from my trailer??

Have you tried contacting the manufacturer of the trailer? They might have a bill of materials and can tell ya where to get it.

Mine is a 5 way that I connect to a 7 blade adaptor, but I have 10 wires coming into the plug from the trailer... all I have been able to find have 6 wires. I’ll post a pic. Have the part number but it has turned up nothing when searching web. Thanks!!

you have a 5 way plug , the 10 wires you are looking are blue wires going to 1 pin , green wires going to 1 pin , brown wires going to 1 pin , yellow wires going to 1 pin , and the white wires going to 1 pin !!! these wires share the same pins; meaning blues to pin 5, green to pin 4, yellow to pin 3, brown to pin 2, and white to pin 1 !!!!!! hope this helps !!!!

That was what I was thinking. Thank you for confirming that for me!

I wonder why it has 10 when a camper only uses 7 and it has charging, brakes and backup.
