• What Circuit is the 5th Pin on 7-Way to 5-Way Adapter for a 2005 Chevy Trailblazer
  
• The Optronics 7 Pole to 5 Pole Flat Adapter, part # A75TB, uses the center pin on your 7-Way as the 5th pin on the 5-Way side. Most 7-Ways are wired with reverse lights at the center, including factory installed 7-Ways, so the 5th pin should be the reverse light circuit. This circuit is used on hyrdaulic brake trailers to lock out the brakes when backing up. Check the cap on the 7-Way or in the vehicle owner manual to make sure that the center pin is in fact the reverse circuit.

• Will 7-Way to 5-Way Adapter Part AT75TB Work with 4-Way Connectors as Well
  
• Yes, the A75TB, 7-Way to 5-Way adapter will also work with 4-Way connectors. It will leave the 5th pin exposed which can cause corrosion if you will be towing in the rain. Part # 37385 is another option. It has both a 5-Way and a 4-Way with covers to protect them from corrosion.

• Will a 7 to 5-Way Adapter Work with an Electric Reverse Lockout On a Surge Brake Trailer Coupler
  
• The center pole on a 7-Way trailer connector is the reverse light circuit. Provided that it is functional on your 2012 Toyota 4Runner, it will work with the electric reverse lockout on the coupler. You can use a circuit tester like # 3808 to determine if the center pole works with the reverse lights. First, apply the emergency brake and chock the wheels. Have someone start the vehicle and keep their foot on the brake and place the truck in reverse. Test the center pin on the 7-Way and make su

• Availability of a 7-Way Round Pin to 5-Way Flat Trailer Connector Adapter
  
• It sounds like your Trailblazer had a 7-Way round pin connector and your Explorer Sport Trac has a 7-Way blade style connector. The configurations are different between the 2 different connectors. For an adapter, using the 7 Pole to 5 Pole flat, # A75TB, that you have referenced would work for you if the Ford has the blade style connector. I have included a picture that shows the differences between a 7-Way round pin and 7-Way blade style connector, vehicle side. If the vehicles both have

• How to Activate Boat Trailer Surge Brake Lockout from the Factory 7-Way on a 2012 Toyota Tacoma
  
• It sounds like you have a factory 7-Way connector on your 2012 Toyota Tacoma and that you also have the dealer supplied electric brake controller wiring harness for wiring an electric brake controller in the cab of your vehicle. Since your boat trailer is equipped with surge brakes, you will not need to install an electric brake controller in the cab of your Tacoma. The first thing you should do is check the center pole, see photo, in the 7-Way connector on your vehicle with a circuit test

• Reverse Light Circuit Does Not Work on 7-Way on a 2007 Chevy Silverado New Body
  
• If your trailer brake actuator has an electric lock out on it then you will need a working center pin on the 7-Way that is attached to the reverse light circuit on the truck. Since your truck has a factory 7-Way you can check the vehicle owners manual for the location of any fuses or relays related to the tow package wiring and/or reverse lights to determine if a fuse is blown or missing. I did see that you found the issue was a bent pin inside the connector. I do recommend checking the other

• 7-Way Recommendation for Activating Trailer Brakes on a Trailer with a 5-Way
  
• Typically, the 5th circuit of a 5-way is for a reverse light circuit. I have a solution for you, but you will not be able to use the Adapter 7 Pole to 5 Pole Flat # A75TB to activate your trailer brakes as it has an empty port where the brake output circuit would be on your tow vehicle connector. I would recommend you confirm that the fifth circuit on your trailer is actually for trailer brakes. You can do this by tracing the wires back from the connector and see if they go to the brake assem

• Compatibility of Tow Ready 7-way to 5-pole Adapter # A75TB with 2103 Toyota 4Runner
  
• The Tow Ready 7-way to 5-pole adapter that you mentioned, part # A75TB is not a vehicle specific item. As long as the 7-way on your 4Runner is fully functional, in most cases the adapter will work just fine for you. If your 4Runner has a bulb out sensor that warns you when you have a burned out taillight, and you are towing a trailer that uses LED taillights, you will need to use an adapter that has a load resistor installed in it, like part # TR20141. Either adapter can also be used wit
