• Identifying Wiring on 1997 GMC Safari
  You have already identified six of the functions on your 7-way, 1) Tail/Running Lights 2) Left Turn/Stop 3) Right Turn/Stop 4) Reverse 5) Brake Controller Output 6) 12V power. The only wires not identified were the ground wire - which make sense if you were testing it with a circuit tester because it would not have an identifiable function - and the other is likely the third brake light wire. If you take a look at the diagram I added you can see the standard pin functions of a vehicle-side...

• What Gauge Wires Should be Used with the Hopkins Connector part # HM48480
  There really isn't a set maximum gauge wire that could be used on the Hopkins Connector part # HM48480. Most people will use 10 gauge wire as the max gauge for the brake output, 12 volt accessory, and ground wires. So you could easily use that gauge or slightly smaller or bigger without a problem.

• Convert a 7-Way Connector to a 9-Way Trailer Connector for a 1985 Fireball Travel Trailer
  We do carry a couple of 9-Way connectors. The one you would need to add to your 2001 Ford would be part # PK12907. The wire color code is listed on the product page, but 9-Way connectors are very uncommon now, so I could not find information as to which position the wires should connect to. What you can do, is pull apart the trailer connector and wire the vehicle 9-Way as a mirror image so that the wires match up when the two connectors are attached. And in case you need to replace,...

• What is Purpose of Reefer Tag/Stop Circuit on 9 Pin Trailer Wiring
  The refrigerator or reefer tag line is the power feed for the thermostat that controls the cooling unit on a refrigerated trailer. It would connect to a 12-volt power source on the truck, if needed. If you are not pulling a refrigerated trailer, the circuit could be used for another purpose or just left unconnected if you do not need it. I have provided a wiring diagram for a 9-way connector that you might find helpful. If this circuit is not complete the refrigerator will not work.

• Upgrading a 2010-2016 Ford Super Duty to 9-Pin Wiring With Separate Center Brake Light Pin
  When upgrading your factory 7-way to a 9-way # PK12906 and # PK12907 as you referenced, there would need to be a separate harness made. To separate out the brake light for that separate pin, you would need to use the Curt Vehicle to Vehicle Tail Light Converter # C56196. This will give your the separate signal for the center brake light you mentioned. The other couple pins can be configured as you stated for refrigeration or aux power as you stated. For another 12V power, you will simply...

• Availability of Wiring Adapter to Convert 7-Way RV Connector to 9-Pole Round Pin on 1984 Jayco
  9-pin connectors are rare these days. We do still offer vehicle and trailer side connectors of this type, such as # PK12907 and # PK12906, but we do not have any adapters that can convert your truck's 7-way blade-style RV connector to a 9-pole round pin type. A 9-pole connector like # PK12906 has two extra circuits (auxiliary on the gray wire and reefer on the orange) that would not be supported if fed by a 7-way socket. You'll want to swap out the truck connector using part # PK12907.

• Wiring 2001 Ford Ranger to Tow a Trailer with a 7-Way Blade, 7-Way Round, or 9-Way Round Connector
