Redarc Tow Pro Install

[blowie Lurker Find all posts View Profile Close blowie]

Hi all,
I know this is probably answered elsewhere but I'm having trouble finding it. I'm paranoid about electrical work so want it right in my head before proceeding.
Have bought a Redarc Tow Pro and trying to wire it myself.

Noticed there's a lumen harness and have a few questions.



1 - Is the blue free wire spliced into number 1? Think I read in other threads about a blue wire so just want to confirm I should be attaching the blue wire from the redarc (12V Trailer Brakes) to this blue wire? Not the red (number 1) 'trailer brake' wire from the controller?

2 - What's everyone's consensus for the red redarc 'vehicle brake light' wire? Should I run that to the back of the vehicle and attach it to:
a - the back of the actual brake light
b - splice it into the number 5 'car brake' on the lumen
or should I attach it somewhere else????
Redarc note to "refer to vehicle manufacturer specifications regarding correct connection point for the brake light signal (RED) wire".

cheers,

--
Mark

1 yes, 2 yes or the wire at the brake switch. I actually ran a new heavier brake wire from the TowPro down through the grommet and into the trailer plug. There is another thread in here about which wire to use at the brake pedal though it is easily checked with a test light or multimeter. I mounted the TowPro module under the steering column and ground out a blank for the remote unit. When you test the TowPro use a trailer as first preference and a test light second. A multimeter won't work.

Neat install of the switch MJ.

What's the lumen harness? I'm about to install my kit.

Sorry, lost. Lumen harness?

That's the black box in the photo - it drives the trailer wiring from the car wiring so you don't blow up the car wiring if the trailer has a problem. I can't think of it's proper name... we've got a Toyota towbar and the box they installed is made by "Lumen"

Ahhh, that is in the back accessed through the Jack opening. Usually visible but mine was hidden around the corner. The blue wire is typically taped to the harness. You can just connect to that which will put brake power to the trailer plug or run a separate wire which is what I did.

I was just going to hook mine up under the dash via the brake pedal and get power from the engine bay.

Interesting about the multi meter and test light with the brakes. I finished installing a Hayman Reece trailer brake system today using their wiring loom. The multi meter showed not much more than nothing at the connector, the test light barely lit up. Plugged the trailer in and it all worked a treat. Trailer brakes fine, relevant lights on dash all worked. Go figure.
