Hi,

Because of the model year, my schematics are very limited. The only thing I found was in black and white and doesn't indicate wire color.

What I did is this. If you look below, I attached two basic schematics for the fuel cutoff solenoid. Look at the orientation of the plug to determine which wire goes to ground.

Let me know if that helps. Also, here is a link you may find helpful:

Let me know what you find or if you have other questions.

Take care,

Joe

The wires are cut, all of it what. I did I join all the wires together run it to the ignition circuit' then ground it.

I took out the fuel cutoff solenoid then watch it when I connect it to the battery, that's how I did it.

Thanks, be seeing you again. Have a great day my friend.

Thanks for the update. The only concern is in the event of an accident, the fuel pump won't turn off until the key is off. That could be dangerous.

Regardless, take care of yourself.
