Alice is beautiful husky ! Thanks for a video .

[Muckhauler]

Good video - personal preference is I’m not a lover of scotch locks and connectors for permanence, far better to take the time to solder and heat shrink 😉👍

[jameshaveron]

Just watched video, great deal of info. I was particularly pleased to see a permanent live in rear of boot, negating the need to run to front of car. Just confirming, was this a Kuga. Ready to watch towbar install now. Why can't manufacturers just leave a dedicated trailer multi plug in rear, as some already do. Thanks for great video

[scoyle]

will be doing this tomorrow, your upload has helped a lot when using multi meter when checking wires do you have black probe on a earth

[MalavDesai]

Great video. I have a xc90 and someone had fitted this relay already and also there is a power source also in the rear fuse panel. I just wanted to see how it was installed while i tidy up the wiring as a previous owner had made a mess of the install.

hi, I know it is 3 years, but I will be installing it soon, all I need to know if I can feed relay from boot lighter 12V and also if I have to put extra fuse adapter on positive between lighter and relay with 20A fuse? thnx

[eady]

thank you very helpful and informative

[stephenkhan]

Hi. Great video. Thank you.
Im trying to identify my cables on the back plug but more than 1 has voltage, i have a volvo v40 and plugs look very similar to yours.

Would the indicator fluctuate with voltage?

Thabk you

I’ve just fitted this bypass and it starts to make a buzzing noise wen engine is on then I put brake on it goes off 😊

[chrishibberd]

Hi at 8 mins in you connected the two blue cables together what are these?
Thanks

[ivelinivanov]

I did exactly what you show but when i connect ground cable from TEB7AS with trailer one its sounds non stop and that worries me. Any help?

[mariuszlubiszewski]

my makes noise when I use indicator, can I switch it off?

[Shreddykruger]

great video..could i run the main live of the cigaret lighter tyoe charge point in the rear of my car..that has a live and an earth already.

[ianjones-wh]

Should also make i clear that this is for a universal electric kit, and not a dedicated. I followed link from Pf jones about relays for my car, but does not mention a dedicated kit.

[Florin_Bolocan]

I would need your help please 🙏
I have a Golf MK7, I’ve fitted the towbar, I’ve routed the wiring of the towbar, I’ve stripped all the trim in the boot and exposed the car’s wiring harness, lights everything.
Now I have a multimeter and back probes and unfortunately I have zero knowledge on how to trace the signals.
Please advise what are the steps: multimeter set on 20V I see in your video, black multimeter lead to a clean ground and the positive to each pin, but then what do I look for ? I suppose I have to turn on and off fog light, turn signal etc and suppose I need to observe a certain variation on the multimeter, what is it that I need to look for ?
I spent 4 hours tracing ‘something’ and I thought I’ve found the signal for each light to then realise that I have actually traced the 12V from each light, and not the signals.
Please help. Thank you

Hey, how much you charge for fitting tow bar and where are you base?

[duncanbooth]

good video, I have a problem with my caravan lights. When I plug into the car all the caravan lights come on. Stop and tail, fog, brakes, indicators. I substituted a trailer board and the same thing happened! Could this be a fault in the relay?

[Shreddykruger]

so you had to run your own extra long wires from left and right light clusters to the relay box?? .

[schmoosmith]

Why does the live feed have to be permanent?
