      1993 GMC Jimmy TCC unlock switch?

      Does anyone know if I can install a switch in my 93 Jimmy to unlock the torque converter when I'm towing. I would like to be able to tow light loads in 4th gear and not have to manually shift to 3rd.

      I know many newer pickups have a "tow" switch and I think it just unlocks the converter.

      I would think a switch in the correct wire off of the TCC switch on the brake pedal would do it, but I can't find any info or schematic to help. If anyone has done this; What type switch will work and which wire is it.

      Thanks; 93 Jimmy
