Re: 90 hp Yamaha alarm wire color?
EAVES
you just flunked outboard systems and electrical systems.
take the next course and try again
.
on yamaha wiring dark green is tach send,pink is alarm send in the 10 pin harness gray is overheat visual,black is ground yellow is key on 12v+ red is constant fused 12V supply, brown is start and white is engine kill.
lt blue is trim up and lt green is trim down and dark blue is choke and may not be used on all applications even though its in the harness.
on the trim meter orange if using a 3 wire sender is a 5V reference,pink is trim pick off voltage and black is ground.
2 wire trim only uses pink and black although the orange is still in the trim hrness.
green on the trim/oil harness is oil level ok send or green lamp, green/red is oil alarm visual for low engine tank level.
remember with one exception all yamaha functions are done by completeing the ground path, the exception being yellow lamp for tank level low on certain engines.
yellow lamp is a function of a ground loss on the green wire to the oil level guage.
surfbass.
if your trying to use the OMC harness,controls and wiring quit while your ahaed and go consult the proper rigging guide and buy the correct parts.
your 90 requires a 10 pin main harness and if oil injected will require the trim/oil harness for oil and overheat visual indicates and trim indicate.
some of the smaller yamahas without trim can use the 7 pin harness and a few of the harness's with 6 pins did not have a key on 12V yellow wire in the harness and cannot be used with anything that is electric start.
so what you need is the correctly set 704 box,the trim/oil harness a 10 pin main harness and a keyswitch panal with alarm,emergency stop ,1992 and up 90 motors use primestart so a keyswitch without choke will work, if you get one with choke it will still work just the dark blue wire wont do anything.
if you try to franken rig this thing the results will leave a bad taste in your mouth at a minimum.
