I have a 2013 CD as well as prodigy RF unit. I tried 4 Chevy and 2 Ford trucks ranging from 1999 to 2013 and none of them had the 12v accessory pin at 1 oclock on the 7 way trailer adaptor on the tow vehicle hot. You either had to do additional wiring in the truck fusebox and/or add a relay or fuse depending on the brand of truck. TOTAL PITA!! I didnt want to wire my neighbors/friends trucks for them, so I finally took it to a trailer shop locally in Tampa (Weldright on Hillsborough BTW), and the business owner sold Tokonsha brake controllers and parts. He had never paired an RF unit though. We verified that he had a hot 12volt accessory terminal at the #4 pin (1 oclock) on his male 7 way trailer plug on his truck, then did the pairing procedure. The only difference was that the RF controller never showed 0.0 in the beginning as the manual said that it would. IT showed (n.c.) which means not connected. When you went through entire process according to the directions, it finally showed 0.0 then was able to be adjusted up to 12.0. I plugged my trailer cable into the brake controller, then the brake controller into my Cayenne. Everything worked fine. TOTAL PITA though!!! SOOOO, you must have that 12v pin hot, and good luck finding someones truck that has it that way, unless they pull an RV. Most regular boat trailers and utility trailers or car haulers dont need charging capability to the trailer EXCEPT the breakaway battery, which none of my friends had hooked up! Tow a $120k boat to Key West for 6 hours with no brake away control!! Sounds stupid but alot of people dont have them hooked up. The euro trucks trickle charge that battery, so dont expect that breakaway battery to recharge on the way to the track. Also I think that circuit has to be activated in PIWIS. This is so that if you have a trailer hooked up to your vehicle, and the trailer has a draw on it from something, and your vehicle is turned off, you dont drain your vehicle battery, as the trailer will pull current from your tow vehicle. To access your breakaway batery consider moving it to a location easily accessed on the trailer with a case with a top that opens to remove the battery for recharging. Wiring a solo hot wire separately with a solenoid and fuse is another way to go. Look at RV websites for this. Hope this helps someone!

Didnt read all of this - but to pair I suggest a Japense truck with towing setup

I used an Armada to pair mine and it works perfectly in my cayenne

my trailer shop used their Dodge Ram to pair, no problems

You can either use a different car to pair with, or do the following with your Cayenne (obtained form elsewhere on the internet):
"The 5 o'clock pin on the RF unit (where the trailer plugs into the RF unit) should be covered with electrical tape and the trailer plugged in to the RF unit and the RF unit into the Cayenne when pairing. Start the vehicle then follow the RF instructions for pairing. Once paired, take off the electrical tape plug the trailer back in an you are done."

I did the second option, covering one pin with black electrical tape for the first pairing.
Took all of one minute or so...works great.

Yes, seems like an unnecessary step though!

Prodigy should just pair it at the factory and save the hassle!

Didn't know this until too late ... had a Dodge Ram as pair vehicle too.

Amen to that.

My 2015 CD with factory installed tow package had the 12v pin hot and the Prodigy RF paired on the 1st try.

That's cool - but I'm gonna drag this over to the 958 subforum which is what this newly awakened thread is about. HANG ON..

I am the OP. I took my Prodigy on my 2013 to a trailer shop, and the guy paired it with his Dodge Ram. Works great now. Traded the 2013 for a 2016. Works same

Anyone know of a source of switched or constant 12v for the hitch 7way connector? Needs to be rated for at least 20amps for the Prodigy RF.
There has to be a source for the factory setup somewhere...

.01 worth of tape to resolve a pairing issue.

It's built in to the factory wiring.

did you get it to work Bob?

rdemarco06

Yes, I tried a Lincoln Navigator L and a RAM 2500 and neither worked, I taped up terminal 5 and within seconds the RF paired. I think my trailer is a little heavy for the Porsche, I think the total weight is above 8K pounds. It seemed like the Porsche was dragging a bit.
