Is a 2000 model 7373 prewired for electric trailer brake controller

[Hiperflyer2]

Hi Folks, my 2K model 7373 seems to have wiring at the 6 pin plug for trailer brakes and trailer power but I can’t seem to find the link to dash for a controller.
Does anyone have experience / advice for wiring this model for brake controller?
Thanks in advance.

I have the same model that had the controller installed when I got it. There should be a harness under dash (lower left) that will be tagged for rake controller.

Thanks, mine has the 4 wire connector under left side of dash, it has 6 wires at back end, but I can’t seem to find the connection between the 2 ends.
If you get a chance, could you look at your 4 wire under dash and see what color wires it has? Mine is marked TRL BRK but it doesn’t seem to go anywhere,it has no grounds or power and I can’t find a Curcuit breaker or fuse for any of the wires.
I’m ready to just start from scratch and run all new wires and C/Bs.
It’s either that or start opening up the 2” diameter harness under dash and follow wires to destination.
Freightliner has told me once that this is the right plug but next time I called, the tech told me that I wasn’t wired from factory SO WHO KNOWs?
Thanks for the reply.

It was wired by National RV not the chassis MFG.

I'm actually having a similar issue on my 03 Tradewinds 395LE. I got up under the dash and did find a 4-wire harness that isnt labeled. I read a forum post somewhere to get the Tekonsha Freightliner adapter, but the harness under the dash doesnt look like that.

I was going to get a multimeter under the dash and see if that harness is the brake controller. If it is, I'm just going to hard-wire it.

Does anyone know if the harness im looking for is built into a wiring package where other harnesses are plugged into for various other functions? or should I just be looking for a loose harness floating around?


Thanks!
