Can anyone advise in layman's terms about the best way to fit a batterymaster to a 2021 Fiat/Burstner with an EBL119.

Is it easy enough to link the leisure directly to the starter? Is it better to go thorough the EBL? Any advice on the practical aspect of getting the wires to and from either source neatly and invisibly.

You need a connection to starter battery, leisure battery and common negative. The amps requirement is very small (about 1 amp) so no problems with wire thickness.

To explain the method illustrated in gerry mcg 's link, there is a 3-way connector that connects to the leisure battery positive (Pin3, red wire) and common negative (Pin1, black wire). What you can't see is that you also need to insert a fuse in the 'Solar' slot, because that controls the connection from Pin3 to the leisure battery. Typically a 15A fuse is used, but anything over a couple of amps will be fine.

Unfortunately on the EBL119 the other pin, Pin2, doesn't go to the starter battery like it does on most EBLs. So the starter battery connection is made by splicing into a wire going to Pin1 of the 5-way connector - that's the brown wire.

The connectors are MNL (Mate'N'Lok) type, available from auto electrical suppliers like 12VoltPlanet. The connector shells and pins come separately. You crimp the pin onto the wire, then slide the pin into the back of the connector until a couple of small barbs lock it into place with a click.

Sorry - 1 more question. Are Mate 'N' Lok connectors all the same size? - is this suitable?

Just go to the 3 battery inputs on the rear of the EBL simple!

Yes those are fine. Note the 3-way is not reversible, it only connects one way. So make sure you push the pins into the correct slot, they are hard (but not impossible) to remove if you get it wrong.
