anyone know for sure if the tompkins harness is the one to get for 97 LX450?
anything else required?
i see three threads that get half way into this and one that seems to do the full install.
also anything else needed except these two items and any cautions about the alarm or other matters?
also anyone know if this EPDK is needed? or if it matters if you install a second battery eventually?
THANKS

Both of those are plug and play to get you a 4 pin set up.
But it doesn't get you the brake circuit, for that you'll need a 4-to-6 or 4-to-7 adaptor....or cut the four pin plug off and just wire direct to the 6 or 7 pin trailer plug.
I set up a 4 pin to 7 pin adaptor so that I can unplug the 4 pin from the 7 pin to hook up my "simple" trailer; or leave the 4 pin plugged into the 7 pin for the "complex" trailer.

So , what do you need?
Brakes obviously, so that means your trailer has an on board battery , becuase if you have electric brakes you need to have an an emergancy break away system that will run 12v from the trailer's battery to the trailer brakes in case the trailer escapes control of the tow vehical. So that's 6 pins, so that the trailers battery is maintianed by the tow rig.
If you have reverse lights on the trailer you'll need a 7 pin. I put reverse lights in mine, because, why wouldn't I want reverse lights way the hell back there in the dark?

You'll need to run at a min 2 strands of #10 wire from the battery through a couple of circut breakers for the trailer brakes and trailer charging system.
If you want reverse lights you'll need a third strand too.

BTW that trailer brake modulal is F'ing aswsome!

you buy the harness that goes to 4 pin connector then buy a 7/4 pin connector output with an easyhttps://i5.walmartimages.com/asr/d1581acd-2e11-4db0-84ca-39203c111028.8f82df25f0c2915e91f772758a510afb.jpeg?odnHeight=612&odnWidth=612&odnBg=FFFFFF, connect the blue wire to your brake controller, think i had to add a charge wire for my trailer. then you only have one or 2 wires that are spliced your don't have to take the7 pin connector apart the wires are already set up. I believe i used the Tompkins harness. it was way easier then having to wire the 7 pin plug. MY 7 pin plug has an additional 4 pin output right next to its output so I am setup if i have to pull a trailer with the 4 plug connector

i did a paste up of the installation guide for the harness so i could print it so i thought to post it here.
(not sure if they are uploading or not actually so i guess this is a test...)
