I need info on the park/neutral switch on the old auto. I know the middle wire is for the switch the 2 outer wires are for back up lights correct? Do I just ground the middle wire to get the truck to start? On the top of the getrag there is a two post termanal what is that for?

 

dono bout the getrag but you are correct on the 3 from the auto. just ground the middle one to start.

 

That's the reverse light switch. Put the other two wires there.

 

Figured it out I just grounded the middle wire and it started. I will connect the other two to the trans for the back up lights..
