CBE DS470 ... replacing SCR with a new RELAY... guidance on connections

[MarkHoughton]

Below is a screenshot of the guidance page from Roger Ivy ( OffGridPowerSolutions ) which is a generic "insert a relay for a B2B/SCR situation" tutorial.
I have ordered ( and received ) his recommended relay so am now ready to connect it.

I just want to confirm all the connection points in relation to the DS470-CA distribution board.

Pin 87A wired to B1 ( on DS470 )
Pin 87 wired to B2 ( on DS470 )
Pin 86 wired to GND ( on DS470 ) or do I make a new earth connection to the chassis ?

Pin 85 ..the D+ I am sure AdrianChen pointed me to that in a previous post.

So that just leaves...
Pin 30 ... where do I connect that ?

Off to the dentist again in a few minutes ( more neglected teeth repairs due to not bothering to have checkups all through Covid ! )

Pretty sure your D+ is the grey wire coming of your DS470 board. - should be 12v+ when engine running and 0V when engine stopped. Diagram labels them Fa4&5

Do I just splice into that wire then ?
Am I correct in thinking the other wires from the relay go to the B1,B2 and GND studs ?
Cheers

Should be fine if the tests show it is D+ (Isuspect the yellow is also D+).

Are you wanting to disconnect the original Carthago feed to B1 when the engine is running, because you have a new 25mm cable connecting the new Orion XS?
