93 Yamaha 70hp Wiring

[brewmister]

I know no one post a wiring diagram but I just put the power head back on a motor and I have alittle confusion with the CDI wiring to the harness.

I have a white/red and a White blue coming off the CDI unit and I have a pink and white coming off the harness.

Can someone tell me where how these wires match up to the harness?

Thanks

w/r and w/b will go from the pulser coils to the cdi,br and blue are stator to cdi,cdi output is bw and black.
blue/red and blue white are from the crank position sensor to the cdi.
the pink goes to the cdi alarm terminal and the white i to the kill terminal.

Well thanks for the info rodbolt but I have a couple wires in the picture I want to show you. on CDI Yellow / red, Gray/blue and that little rubber Relay?

White coming from harness and pink from harness.

In the picture the white from harness is going to yellow/red CDI.

I have gray/ bl from CDI going to rubber relay and Other end?

Well I figuring that none of the wires control the starter. I can not get the motor to turn over with the key. I jump the relay and it turns over fine.

Does anyone know the wire combination in the picture?

Motor starts and runs like a champ! one problem it wont shut off. I know my white wire is my kill but I assume it goes to white coming out of cdi. But it wont kill the motor.
Does it go to ground to kill the motor?

Any help would be greatly appreicated!
