Ok thanks Spruce.
I am pleased with the reel but I think there’s definitely potential for an accident. I was expecting some sort of clutch/torque system like on a battery drill for when it gets stuck. Not just blow a fuse or yank your arm in. Have only blown the fuse once when i first had it & i got caught on a gate. You’ve also got to be careful to let off the button in plenty of time before the rectus fitting comes flying round the corner towards you or your van.
Here are a couple of YT videos on connecting up relays.

The rest is per a 4 pin relay.
I guess the reason why I always link to a 5 pin on Ebay as they are the most commonly sold. I have a spare relay with connector in my parts bin. Not always but generally a 4 pin relay is 30amp and a 5 pin is 40 amp. IMHO you need a 40amp. I also see the 5 pin is cheaper than the 4 pin.
The controller that Spring make does have an anti snag (dead end) facility. So in reality, it's a much more robust flow controller most of us use every day.
