MONTE CARLO Wires cut On Torque Converter Lockup. Need help on wiring harness

[junkyard junky]

Trying to find the exact wire to hook back up on my 87 Monte Carlo Aerocoupe. Had someone change the factory carb, distributor and intake out. For some reason the three wires to the torque converter lock up switch on the trans were cut off. The three wires on the switch are a solid purple, green with white strip and a dirty white with a stripe. In the main harness, there are 2 purple wires and 2 dirty white with stripe wires. Checking to see if I could find a wiring diagram or figure out which ones did what. Looked at the factory service manual but about went crazy.
