wiring in split charger system

[KarlT]

I understand the basic principles but can someone please give advice on where to take the relay trigger wire from on a Caravelle.
Where is easiest to connect and run wire? Cheers

On my velle it runs under the van to the "W" terminal on the back of alternator.

Damn, sorry I should of said. I've a Subaru EJ25 conversion. Alternator has a sealed plug.
Anywhere on ignition?

The easiest way would be to buy a SMART voltage sensing relay that doesn't need a trigger...simply connect battery to battery (with a 40 amp fuse) and let the relay do the rest. Otherwise I fear you will need to trace back the ignition lamp feed and use that.
