I have a 1995 Mitsubishi Diamante. I purchased an aftermarket shift **** with O/D but the instructions only explained how to wire a car with two wires coming from the car. My car has three wires! I don't know how how to wire this and now my overdrive is off and the RPMS are high! I don't want the wear and tear on my engine seeing as my engine is old! Can someone please explain to me how to wire this up? I'm open to adding a custom button for the overdrive on the console and not using the button on the shift! I Just want to fix it!
PLEAS HELP!!
