TC Lock-Up Switch

[RacerBoy21c]

I have a 97 F-250 and have previously wired my EBPV to a manual switch for use as an exhaust brake.
I would like to run a second switch so i can manually lock my torque converter. Does anyone have information on how to do so?

-Thanks

I don't know, but you got me curious:

I found several threads in the OBS section on TC lock-up, but none actually describing how to do it. I did find a couple dead links though.

Hopefully someone in the know will chime in.

Edit: Found one: http://www.guzzle7pt3.com/tclock.php Although that's for a SD. Hopefully it's the same.

And if you figure it out, feel free to post it.

Ok so I found the answers i was looking for on a Bronco forum. It's actually very simple.

All the wires for your transmission run down the drivers side frame rail and then go across the top of the transmission. Pull the wires out of the loom and find the purple with yellow wire. Run a wire off that to a terminal on your toggle switch and then connect the other terminal to a ground.

To test this when your done put your truck in drive, turn the switch on and then press the brake. If the truck stalls the mod was successful.

I hope this is helpful to anyone else interested in doing this mod.
