Recommended Wiring For Brake Controller In 2007 Lexus GS430

Question

Question:

Hi, I have a Tekonsha Primus IQ brake controller like your item # TK90160. Id like to move this controller into my Lexus GS430 2007 model. Is it possible for me to buy a loom with plugs to plug in under my dash? If not, can you sell just the plug and loom for me to wire it into my 2nd car? Many Thanks

There is not an adapter harness for your 2007 Lexus GS430. To hardwire this controller to your system you can use the Replacement Brake Control Plug-In Harness for Tekonsha and Draw-Tite Brake Controller 12" Long # 20127 to allow you to use the controller between two vehicles with the quick disconnect.

I don't see the wiring needed for your vehicle to use a brake controller, so you will need to do some custom wiring. If you don't have a 4-way flat connection, I recommend the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT along with the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires # ETBC7 to give you the connections, circuit breakers, and wiring needed for a functioning 7-way with brake controller. I've attached videos to assist with this installation.

Answer 1

A brake controller is going to need to be hardwired into your 2002 Holiday Rambler Endeavor because there is no plug available. In order to do this (since I assume it already has a 6-pin wiring harness in the back) you will need to cut that and…

Since you already have a 6-way on the back of your 2001 Holiday Rambler Imperial it's possible there's already a brake circuit. However, since the previous owner was towing a vehicle it may not and you'll need to check for a wire running…

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…

For your 2000 Holiday Rambler Admiral, I recommend the Tekonsha Prodigy P3 #90195 brake controller. To install this, you can use the wiring harness #3035-P. For most applications, the factory plug is located beneath the dash, near the center console.…

You'd want to use the 20 amp circuit breaker like #PK54220PL unless your trailer has more than two brake axles. If that's the case you'd want to use the 30 amp breaker #38630.

Answer 7

I recommend using at minimum a 12 gauge wire like #12-1-1, but preferably 10 gauge wire like #10-1-1. When you try to run 12v power for electric brakes through a thinner 14 gauge wire to power something like your brakes it overloads the wire and…

Hi Andrei; yep, you're 100 percent right, you should use the 30 amp breaker. That's why for the installation kit I recommend using the Universal Installation Kit for Trailer Brake Controller #ETBC7. The #ETBC7 comes with multiple breakers,…

To duplicate the Universal Installation Kit for Trailer Brake Controller, #ETBC7, minus the 7-way, you will need the Wiring Kit for 2, 4, 6 and 8 Brake Electric Brake Controllers, #5506, Hopkins Trailer Wiring Installation Kit, #HM51010, 40 amp.…

On an 4 foot long section of E-track #EM19147 and 2 screws every 16 inches that is a total of 6 screws in the aluminum frame. This most likely will not get you near the capacity of the E-track. I recommend bolting through the aluminum frame so that…

You'll need a 20 amp circuit breaker for the brake controller power and a 40 amp circuit breaker for the battery charge line circuit from the trailer connector for a total of two. We actually offer a kit with these circuit breakers as well as the…

Answer 12

The Hopkins 6 Pole to 7 Pole Adapter, #47435, does have a pin for the brake output for a brake controller. This adapter will work for your set up as long as the center pin of the 6-way plug on your RV is for 12v power and the pin in the 10 o clock…
