87 rx trans wirining ???

there 8 wires coming out of it, 2 connectors, the first connector has 2 wires and they indicate that its in gear, any gear, i figure this is the nuetral safety, but are not strong enough to loop the starter inhibitor through, the other connector has 6 wires, 2 (green, and green/red i think) are the reverse indicator, then there are 4 other wires that are 2 black and 1 blue, 1 green/?, i figure these are the 2 range indicator switches but i cant get anything to work off them, any combination, nothing, does anybody know the brake down of the wiring on a 87 rx trans w/ diff lock, dual range, 4wd/fulltime, help please the rx wagon almost lives
