Almost ready, last Q's before I start
ATF or gear lube works. I prefer 90 wt gear lube over ATF.
The safety switch is just a circuit completion switch. You can wire it in using the auto trans harness. The switch itself should be on the pedal assembly.
It's the switch on the right.
If the trans plug is good, pull the entire harness or cut it off a ways away from the plug and sell it. It's worth a few bucks.
Knock the pin out and the shift arm should come off
