90hp yamaha and trottle unit

[Gramas]

Need some help in working out the mess my brother left me in, I work offshore and been refurbing a rib we bought , it's finished apart from throttle unit but my brother has not taken pics or marked up where the wires go from the trim guage go yellow green and black, they were in mess on old console so he disconnected them off throttle unit to feed them out console,
Problem now I have is there is 2 loose yellow and 2 loose black in console so I'm lost as to which ones they connect too?
Will get pic up 1st thing in morning

Have you stopped slapping your brother about the head yet?

Looks like you have a Yammie 703 PTT unit there. It also looks like it needs a thorough overhaul! I'd mark existing wires with coloured insulation tape and indelible marker and strip the whole lot down and clean it up.

Use a marine grease such as Duckhams yellow grease on the nylon bush on the throttle lever and rebuilt it. The bullet connectors can use a light sand with fine-grade 3M paper and reconnect. Any worn or loose spade connectors, then replace, solder and shrink wrap with a protective sleeve.

Regards wiring, try this illustration. The green wire is your tacho or pulse from main engine, black is ground, and yellow is ignition supply to gauges.
