It is mounted on the trans selector shaft. Get the new one and match it up

it would help to know the motor and trans to be more exact

Thanks for the quick reply & diagram. Not sure if this is the problem but it's a starting point. It will not start all the time in park or neutral. Have to play with the key switch then dadahhhh. She's running!
Appreciate all the input I can get :)

Do you have a test light?If so next time it won't turn over with everything plugged in put the key in the start position at the park neutral switch you should have power at the blue wire and the red wire. Let me know what you find.
