I recently replaced the factory-fitted split-charge relay (SCR) in my T6.1 camper and replaced it with a Victron Orion XS (along with a Victron Smart Shunt and Ablemail AMT12-2). In place of the SCR, I fitted a box of the same external dimensions as the SCR along with an aluminium strip riveted to the box casing and connected the starter battery feed to a fuse holder fitted with a 60A fuse. It fits exactly into the plastic holder and uses the SCR retaining clips. The other side of the fuse feeds into the Orion’s input terminal. The output terminal goes to the +ve terminal on the auxiliary battery (see second picture). I replaced the 200A fuse with a 60A fuse as per Victron’s recommendation so both the input and output +ve leads are protected.
For the record, I managed to find a suitable connector online for the SCR’s engine-run plug so was able to plug the original connector into this to provide a 12V ignition-on feed to the H terminal of the Orion. This meant I didn’t have to hack off any VW wiring or shorten any factory cabling so it can easily be returned to original if ever needed. Hope that helps.
