5-speed swap problems

[slidinsidewayz240]

i got threw with a 5 speed swap on my 91 240sx a while back and i cant figure out how to get the reverse/parking lights to work. i got the car to start by jumpering the two wires together, but now im stuck, if you have completed this swap before tell me how to wire the car correctly.

back up switch on the trans to the ECU wire for the lights...i'm sure the colors are out there if you look. this has been done many times.
