Right I now know the light blue, green , and red loom from controls is for extra switch and can forget about it!!!
So will get pics today of the two leads coming from engine that have connectors on that plug into lcd marine meter!
Also have 2fuse harnes that links loom from 703 control throttle to tachometer!
I think from what I've found out guys on yamaha outboard forum I may be alright??? What you think????
