42RH / A-500 in a Duster with pictures.

thank you thank you thank you!!! :) I definitely want to do the rest to make it automatic but right now time is not my friend.

I hear ya.
I have all the part numbers for the switches and can describe how I ran and routed things, then you can decide how you want to do yours.
The governor pressure is plumbed of the governor pressure test port on the rear of the trans and steel cooler line runs up the back of the motor to a bracket on the back of my intake.
This makes it so I can set shift speeds from under the hood instead of under the car like most kits.
