Optronics Wiring A75TB Review

Video Transcript for Optronics Wiring A75TB Review

Today we're going to review part number A75TB. This is the Optronics 7-Way Blade to 5-Way Flat Adapter. Now, this adapter will convert your tow vehicle's 7-way blade connector right here into a 5-way flat pin connector. This model is a nice molded 1 piece unit, has the connector on each end, and also molded in as this nice, easy grip handle, which you can use to plug it in and also to remove it. As you can see here, it has the blade design for the 7-way and then right here for your trailer to hook into, it has the 5-way flat. Now, you can also install a 4-way flat on here. You just don't use that end pin.

That end pin is used in a 5-way. It gives you the reverse light circuit. Because on a trailer that uses a 5-way, it needs that reverse light circuit to activate the reverse lockout on the surge brakes on the trailer. on the 4-pin, it's not required so you just plug a 4-pin in by using the ground and you just don't use this end pin. That should do it for the review on part number A75TB. The Optronics 7-Way Blade to 5-Way Flat Adapter.

  • 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.

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...

If the 7-way/4-pole connector on your truck is factory installed, the center pin of the 7-way should already be wired to the reverse lamp circuit of the vehicle.
