Trailer brake pin questions. And trailering questions

[Captain Ron]

If you have a seven way plug on the tow vehicle, the blue wire is already there, so all you have to do is buy a seven way to five way adaptor and you will be good to go. I paid about $25 (cdn) for my so they are very affordable. I just dont understand why people tape pins or nickels in there and drive down the highway. It disables the brakes and could cause problems.

I'm using an adaptor to make my 4 pin into a 5 pin on my Jeep. If I already had a 7 pin on my Jeep, I'd get this to attach between a 7 pin vehicle and a 5 pin trailer (like my trailer):

Glow LED, coiled cable, 7 to 5 pin...very cool!

@genwrx this thread answers all the questions. I know you were looking at your pin the other day.

@Swimmingly I'm confused... you have a four pin on your Jeep and you're using an adaptor to make a 4 into a 5 - presumably the adaptor has an extra lead that you've tapped into your reverse light circuit wiring? Otherwise a five pin male (trailer) will plug into a 4 pin female (vehicle) without a need for any adaptor - but you still won't have brakes...

That's correct. My word choice might have been confusing...

This made my oem Jeep 4-pin into a Yamaha boat trailer 5-pin:
4 to 5 pin connector (the 5th wire crimps onto the vehicle's back-up/reverse wire)

I considered converting my Jeep into a 7 pin, then using an adaptor to attach to the trailer's 5-pin, but Clemson Tiger convinced me to just use the 5 pin connector in my link. Very simple.
