Pinouts for 93 4l60
(A) is BAT + for the lockup solenoid
(B) is 4th clutch
(C) is 3rd clutch
(D) is BAT - for the lock up solenoid
(E) is 2nd clutch
This harness also has a plug for a temp switch that is pig tailed in with the ground wire for the lock up solenoid and the 4rd clutch pressure switch. I'm positive on the power and ground terminals for the LU solenoid if this is what you are after. HTH Vince
