Tow bar 12S socket via self switching smart relay.

davevicki · February 2016

Could I pick some brains please.

At the weekend I am fitting my tow bar with a 12S socket and using a self switching smart relay,

The relay has these connections.

-VE Earth

Switched O/P

Permanent O/P

Switched O/P

+12v Input

In my mind this is how I would wire it, could someone confirm or correct me if needed.

-VE Earth. -- Self explained, to vehicle body.

Switched O/P -- Blue wire for caravan batt charging.

Permanent O/P -- Green wire Perm fused feed

Switched O/P -- Red wire for fridge

+12v Input -- Fused wire direct to battery

+12v Input -- Not sure?

Whilst wiring yellow wire to reverse light and black to earth..

Many thanks for anyones help.

Yes thankyou, it was the twin 12v input connections that confused me, many thanks for your time.
