torque converter lock up

[vic3373]

I have a 1998 Chevy Diesel 6.5 Turbo 4 wd with an automatic transmission. I was wondering if anyone could tell me which brown wire on the harness needs to be isolated so I can put a toggle switch in line to keep the torque converter locked up. I was told a brown wire and when I looked today, I have 3 brown wires and 1 black wire with a white stripe. Does anyone know which one I should cut?!?!?

Vic, where did you see you can do this? I thought this was only possible with OBDI?

Read the title - not for your truck. Only OBD1.
