I need help finding a wiring diagram of my hatch switch circuit. My manual does not show this circuit for some reason. I'm converting from a 700R4 to a T5 and looking at the wiring that went through the gear selector switch on the auto shifter. There is a yellow wire that goes to the neutral switch, but also goes to a relay that is connected to my hatch switch.

I need to trace this as I won't have the neutral switch once I'm done with my T5 conversion and I want my hatch to open as usual.

Anyone have this diagram to share?

 

 

I understand what you are suggesting, but the purple wire is going to be used on the clutch switch (in place of the neutral switch) to prevent starting in-gear.

What I don't understand is how the yellow wire from the ignition start switch is also used in my hatch circuit? I'm thinking that they might have tied the hatch circuit in with the neutral switch somehow so you can't open the hatch when in drive or reverse. But without the neutral switch anymore, I must have to do something else to make my hatch switch work.

I'm hoping someone has the hatch circuit diagram for 84 that I can look at.

 

 

You seem like you're on the right track there with the yellow wire from the ignition switch and the purple wire from the starter going to the neutral safety switch now instead of the gear select.

There should be a yellow wire on your hatch release relay. Automatics it will be connected to your selector switch, manual it connects to the e-brake switch. It completes the ground when the e-brake is applied allowing the relay to work when the button is used to unlock the hatch.

 

Thanks to both of you guys for the advice. Tonight I connected the yellow wire from the hatch relay to the parking brake switch and it works like a charm. I kept the parking brake lamp wire connected as well with no diode or relay and both the lamp and hatch work when the e-brake is pulled. Problem solved!
