desperate help needed (back up light)!!!

[djsteveyk@shaw.ca (Jody Bailey)]

It's not often I am desperate...well not with the car anyway, but I am 
asking for anyone's help because I really need it to get this car sold so I 
can move already.  Now I went through the archives and found no answer to 
this. Here's the story, and I will keep it brief...

Put new switch in and the back up lights don't work (check the switch and 
it works fine).  What mechanism is it that triggers the switch in the 
transmission?  Am I going to have to tear into the tranny to get these damn 
lights to work??? And no this is not a crazy obsession to have back up 
lights.  I need to have them to pass a safety here in SK.  If I just 
complete the circuit on the connector (black wire and bk/gy wire) going 
into the passenger compartment the lights work so it has nothing to do with 
the fuse box or wiring.  I have it pretty much narrowed down to the switch 
not getting triggered, therefore not completing the circuit and lighting up 
the said stoopid ass back up lights. So if anyone has any experience in 
this, or just some suggestions, before I go tearing into the transmission 
please contact me ASAP!!!  TIA
