Hi all - Sorry if this is elsewhere but couldn't see it

I'm just fitting a couple of 12v sockets in the front of my troll and thought I'd plug them into the controller. There's a spare 5 amp fuse at on ther bottom row which would be perfect, except that I'm confused by the symbols which don't seem to correspond the - and + sections in rows 1 and 2 above.
If someone could explain please: PU- PU+ I guess speak for themselves but then PS2 PS1 PS1 PS2...

Really grateful in advance!

Thank Colin - I've got negative brown and positive blue! It looks as though that's not unusual though. I'd still like to use the supply unit though....

OK so its for a pump control apparently but even the pu+ and pu- don't seem to be a simple pos/neg. Anyone......?

The PU+ and PU- are a pump supply switched by either PS1 or PS2. So by bridging the two PS1 connections you’d enable the supply at PU.
Might be easier to connect to another circuit output if there’s any spare.

Thanks for that. Presumably an inline fuse from one of the 15A outputs would do?

That would be fine.
Circuit 5 is supposed to be 7.5A fuse so you could connect directly to that one if it has a spare connection.

Thanks!
