Trailer Lights Logic Circuit & Step Down Voltage Converter

[jfrench]

Has anyone used this in conjunction with a brake controller?
Looking to set up an HJ61 with a controller and 7 pin connector. I was going to order a redarc but then I'd still have to do something for the turn signals it looks like, so I am wondering if I could run a system like diagram #3 into a brake controller, and then have a converter to power turn signals and charging into the 7pin connector, along with a second relay system for the turn signals.

Thanks!

That's kind of what I did on my BJ74 for towing a camping trailer. I have the Redarc Tow Pro with 24v input and 12v output going to the 7 pin e brake wire and the logic circuit/step down converter controlling everything else (except reverse lights).

Tow-Pro™ Electric Trailer Brake Controller - REDARC

I still need to get a circuit breaker for the tow pro and tie it into my 24v brake signal but am confident it'll go smoothly and work appropriately. The logic circuit/set down converter works as advertised.

Thanks, they'd recommended that unit to me but I was a little sketch on inertial controllers. When I got to realizing I'd have to run a converter and wiring anyway, I took a crack at a diagram based on the initial and 3rd post in this thread and another thread on wiring a 7pin on an FJ62.

Its not pretty- is it a bad idea to run the 12v across the running lights, brakes and then into the brake controller and 12v charging on the the 7pin? Wondering if there might be more amperage into the relays than I want.

I'm sort of using the 24 to 12v converter as a circuit breaker as well, need to do some more research into that.

Thanks!

Looks like they've changed the part number on the relays to

Any update on the 7 pin connector?

Any update on the 7 pin connector?

I finished it up a few weeks ago and have pulled a car trailer a few times, works great!
I wound up using a samlex voltage converter after getting a couple bad pyles.
What I did was use the plans on the first page without any modifications.

But I added another relay separately, that I stuck to the drivers kick panel. For the brake controller I got, I ran a wire from the brake pedal switch (cold side) to the relay, so that when I step on the brakes it switches 12v through the relay, and into the brake controller.

The "battery" wire for the brake controller is just a 12v coming straight from the converter.

I also added a switch that lets me shut the converter off when I'm not using it.

okay,
i got a quote back from England and the converters are:

BATCH / ORDER QTY: DESCRIPTION UNIT PRICE£ STERLING(EX-WORKS)
1 – 10TAKEN IN1 BATCH E679 – MK2 (AVC19 – MK2) TRAILER VOLTAGE CONVERTERFOR VEHICLES WITHOUT ENGINE MANAGEMENT SYSTEM £49.00 EACH
11 – 50 TAKEN IN1 BATCH E679 – MK2 (AVC19 – MK2) TRAILER VOLTAGE CONVERTERFOR VEHICLES WITHOUT ENGINE MANAGEMENT SYSTEM £45.00 EACH
1 – 10TAKEN IN1 BATCH E805 TRAILER VOLTAGE CONVERTERFOR VEHICLE WITH ENGINE MANAGEMENT SYSTEM £49.00 EACH
11 – 50 TAKEN IN1 BATCH E805 TRAILER VOLTAGE CONVERTERFOR VEHICLE WITH ENGINE MANAGEMENT SYSTEM £45.00 EACH


so a group order will be $106 each vs $116 for a single order plus duty, taxes and shipping.
so if anyone wants one let me know and we can save on the shipping and an addition $10 for mor ethan 11 units (the last call recieved 3 responses so i kinda doubt i will get many more than that)
if interested email me at
wayne@crushersrule.com
cheers

I ordered one of the E805 today, will have to sort my rear electrics out.

How is the feedback on this unit, after all theese years?

Hey guys, super old thread but I'm trying to build my own trailer plug for my 82 BJ42 diesel (24V). I have a sweet aluminum 5x10 trailer with brakes that I've had for years and always put brake controllers on all my trucks for convenience. Trailer also has backup lights. So from what I understand I will need:

1. 24V to 12V converter (my trailer is 12V and I want to keep it that way). Seems like people are buying the E805 which is made for this purpose OR using the relay set up earlier in this thread?
2. Brake controller - I have a regular one, although the REDARC is a rabbit hole I'm tempted to go down mostly because of the dash design of the 40.

Anyone have any actual drawings or confirmed installs for a 7 pin (with brakes and backup), brake controlled 24V unit?

many thanks, some pics of my trailer behind all the different cars over the years! I'm a closet trailer enthusiast I guess.

If you scroll up a bit, you will see my image reply with a 12v brake controller and 7pin. The two partly scratched out wires are wrong. The parts of them which aren't scratched out are correct, though. I have been running it for several years now.
