I know that this is not the correct replacement for the tacomas factory plug but want to install it anyways.

That bracket is specific to some vehicles; if you could tell me what vehicle you have I would be able to give you the appropriate vehicle wiring and mounting options.

I went out to the warehouse to measure the dimensions of the oval socket of the Hopkins Multi-Tow Trailer Connector # HM11141144 and found it measures 4-1/4" x 2-1/4". I have added a link to a video review of this connector for you to take a look at as well.

I have a 2019 Durango w/o factory tow option but with a MOPAR receiver that I need to wire for trailer. The opening for the factory 7/4 way connector appears to be exactly the same as this unit. The opening is circular on one end and rectangular on the other. Hole dimensions: total length = 3 5/8, rectangular width = 1 5/8, circular diameter = 2 . Is this a psuedo industry standard? Can you verify if this unit will /snap into this opening? Thank You.

You will need # HM40975-11933. This part is designed to fit into the opening in the back of the 2019 Dodge Durango.

For future reference. I ordered the Hopkins HM11141144 intended fro Chevy/GMC from etrailer. The 7/4 pin unit fits perfectly into the MOPAR OEM receiver hitch opening MOPAR part 52124606AF. I also ordered the Tekonsha # 118617 Trailer Wiring Kit from etrailer. The HM11141144 provides a pigtail allowing me to splice to the Tekonsha ouput to provide a factory 7/4 interface. This is lacking backup and electric brake service however. I tow a boat with surge brakes so this is OK for my use. I would like to know what is the easiest way to tap into the vehicle backup circuit so that I can wire it into the receiver interface. This would provide for brake lockout when backing up via the trailer brake solenoid.

The easiest way to get the reverse light signal is to pull one of your tail lights and tap into the reverse light power about 6 inches from your socket. Then run a jump wire to your wiring harness. I recommend using the Deka Heat Shrink Butt Connector - 16-14 Gauge - Nylon Insulation - Blue - Qty 5 # DW05744-5 and Primary Wire - 16-Gauge - Black - per Foot # 16-1-1.
