lcd gauge and wiring

[jeff-bateman]

greetings:
am restoring a boat with an early to mid 90's (unable to verify) yamaha "precision blend" 150 hp 2 stroke v6 outboard. biggest issue is electrical. systems work 1 time then not another for no aparrent reason. would probably order wiring harness if could identify. recently replaced LCD marine meter with identical model. on the face is tach, on left, with 3 oil icons below (red, yellow, green) and what appears to be trim gauge set as a verticle bar graph on the right.
rear of gauge has a blue wire and a black wire (lights?). second bundle of wires consists of 8 wires (pink, orange, green, yellow, green with dark red stripe, green with white stripe, black with white stripe, and black) coming out to 3 songle wires (green, yellow, black) and 2 plugs. plug 1 has 2 wires( green with white stripe, and green with dark red stripe). second plug has 3 wires in ( pink, orange, and black with white stripe) and a single gray wire leaving the plug.
based on this info, is there any to identify what wiring harness should be used?
thanks much...
Jeff-Bateman, still in drydock...

Hi Jeff

I am having the same issues with the same setup. Did you ever get it figured out?

Thanks

Without the model number of outboard can't say what you would need.
There are several old post here on forum on Multifunction gauges or digital gauges that might help.
