CBE SRX250 wiring diagram

Does anybody have a wiring diagram for the above ?

I need a D+ feed for my Votronic vcc1212-30 B2B and this is right next to it but the D+ input wire - cannot start engine to confirm - so need wiring diagram.

Any of this help?
These are photos of a duff CBE SRX250 that I have.

The converters socket may be another option for a D+ signal.

Thanks for the photo's, I was hoping somebody would have a wiring diagram, as it will show what the leads connect to, rather than what the board does. I think the SRX250 does what Misterg has done with a relay.

Surely the D+ going into the CBE SRX250 is a D+ from the alternator, so why not tap into that rather than look for a relay output, as your Voltronic B"B will only be looking to be triggered by the D+ rather than drawing any real current.

This is what I'm trying to do but want the input cable not the output and a wiring diagram will show this. The CBE SRX250 is fitted in a very awkward location in the bottom of the wardrobe and an absolute pain (literally) to get to.

A quick test session this afternoon and the left wire on the middle connector is the D+ wire.

Yes, the case on mine is marked as such, is yours not then?

I assumed the symbol referred to the whole connecter, not the end wire.
Ignition off :- 0v,0v,0v,0v.
Ignition on :- 0v,12v,12v,12v.
Engine running :- 12v,12v,12v,12v.
