Need Wiring Diagram
 

I need the wiring diagram for a 93 Chevy 2500 HD turbo diesel.
the circuit that I am looking for is the lock up torque converter .
from the computer to the trany.
My torque converter wont stay locked up after it heats up.
I believe it is a loose wire connection or a bad relay because if I hit a bump in the road it will unlock then lockup again.
HELP
