I'd appreciate any info about connecting to spare terminals circuits on REAR sam.
Ideally like a spare circuit on if ignition on. (acc +12V)

There's a few spare / unused terminals, one I'd like to use is for the pts, (13 / 16 ??) but both have no power at the mo'. Some have power all the time.
Do they need a relay. Basically I'd like to use a spare for parking sensors (aftermarket supply) and have read loads of posts regarding spare rear sam terminals. But besides a diagram or two, where can you get the individual proprietary plugs for the connections and are there any special for aux etc.
There seem to be a few at the base marked amplifier, but look like something else is meant to plug in them.

many thanks

I thought that most wired the rear after market module to one of the reverse lamp circuits?

The fuel pump relay is ignition live and often in the rear SAM,,this is an ideal place for the 12v

Thanks, it does - this is just for the 12v supply.
I was hoping to stay clear of vital circuits like fuel pump etc. But if I did how would you connect.? Just splice the cable?
Is there no way of using any of the spare unused terminals?

I can try and look this up ,,re any spare fuse holder,,these often have a 12 bus bar ,,put a meter on one side of the fuse box and see if you can find one that is switched via the ignition. I have spliced into my fuel pump relay for additions to my car,,no problem with an in line fuse
