Oops sorry, it is a 1991 Mustang GT. Started life with an AOD, converted to a Tremec, and now the C4. I have the neutral interlock bypassed, but will have to revise for the new shifter. The new shifter is set up to handle a park/neutral interlock switch, but I don't see anything for backup lites. I'm thinking I will have to add a contact switch for reverse and was wondering if anyone had suggestions.
