Towing - trailer wiring kits

Ran into a situation where the logic unit from my trailer wiring kit fried.

What do those of you who tow with your older land rovers do to go from the euro-7 to us-flat-4 without back-feeding the lights system?

This is what I was using just for reference:

That ^ is a better taillight converter than the one I use. I bought mine from NAPA and I am sure they also sell a circuit protected model like the one above.

This is what I bought, but all of my trailer lights are LED and I only have brakes on one axle, so did not need the extra juice.

I have exactly the same one and recently had an issue with it. Thought it was the box but it was just a bad ground. Reattached the ground wire to good metal and all was fine again. Worth a try ...

Thanks for the input, everyone! I'm going to pickup the napa unit since it's in-stock locally. Should that not work there's still some time to order something else.

Tried re-wiring the end-points already - Wires outside of the control box are fine. Power isn't transmitting between the brakes and turn signals within the unit. I tore it to pieces last night and found several shorts internally that I'd rather not address.

Hey guys. First time trying to get my 95 NAS 90 UHaul ready. I see my 7-pin connector behind the right rear brake lights. But that adapter looks like it has a different male/female configuration than mine (attached). Am I barking up the wrong tree?

Thanks!

I'm not sure what the electronics module does, but the 7-pin to US-style 4-pin adapter is available at etrailers.com for 20 bucks.

It combines the turn signals with the brake lights, so that they work like old, dangerous American cars. You never know which way grandpa is turning if he's pumping the brakes too.

It also prevents back-feeding . Without it (at least for my RRC's) it turns your turn-indicators into brake lights and turn signals.

For me, I ended up splicing the roverparts euro-7 male adapter into the NAPA converter unit then used a standard flat-4 to the trailer. I connected the spliced-adapter into the secondary euro-7 female plug located at the passenger taillight

That's actually what I'm most interested in, since I want to hook up my brake controller in the 130.
