Hi, after converting my RIB a few years ago from twin to single Mercury 75s, I have an adjustable stainless engine link bar, a rev counter and a sync gauge. Been kicking around the garage for a while but still may be of use to someone.
I'm also looking for a working fixed vhf, age unimportant, dsc unimportant.
To be honest I can't remember how it was connected. On the back of the gauge you have 4 terminals
G - Ground
I - Ignition Live?
S - Signal
4th Terminal isn't marked
I believe the gauges were fitted when the twin Mercurys were fitted so the gauges are probably made by Quicksilver, might be worth trying them for a wiring diagram
