The new loom was cut in half with a jig saw blade but thats no matter really as now the panel can be removed from the boat and serviced on the bench when required.
Note, I have two complete Perkins 4108 wire looms, they both have different colour wires, so please be advised.
One is in great shape and I suspect the loom is from a later engine which I also have!
How your panel is wired is anyones guess but the gauges should all be the same VDO made type? wire loom colours are standard Lucas I think?
