Works well, but no instructions!
This relay works impressively well - once installed - and that’s why it got 4 stars! On the packaging it clearly states, ‘Instructions Included’, but they simply weren’t. There was mention of a website, but going there led to an indecipherable list of loads of different products, none of the links having the same number as any part number on this item - a tedious search was needed… Even when I found the right link, there was no wiring diagram, just words, nothing like as intuitive as visuals… So, 3 websites later I had instructions and could install. The only nuisance in use is that occasionally the turn-indicator beeper ‘warbles’ unpleasantly and sounds cheap. It’s great value and - subject to these reservations - recommended.

Saved the day
I ended up with two distinct wiring faults on my car - caravan brake light circuit. One slightly subtle fault turned out to be the towbar relay . It would hold voltage when testing the brake socket but the lights didn’t work on the caravan when it was plugged in. As we were about to go away I got this nearly identical replacement. After some time tracing all the wires and splicing them back in place in the boot of the car it all worked perfectly. Saved the day and we went away!

Check wiring diagram instructions
Wiring table instructions inaccurate!! Can't say that I'm impressed overall...
