Lockup switch doesn't disengage

Hey guys,

As some of you know, I've had a lurking OD/Lockup problem for a while now. I have finally made some time to hook up the lockup switch which solved all the shifting problems I was having. The only problem I had was I couldn't disengage the lockup clutch with the switch I installed. I followed the instructions exactly as they are on the TST website, so I guess the only thing that could get screwed up is my wiring to the switch. Here's a diagram of how I wired it (ignore the dots):

B11 Ground
| ..........|
| ..........|
| ..........|
P--------P
......|| <-----toggle switch

I know it's a terrible diagram, but it should give you the gist. I tapped the orange wire with black stripe from the center PCM connector and ran it to one of the posts on my toggle switch. I ran a ground wire from the second post on my toggle switch. It should disengage when the switch is flipped, right? And of course, I installed the jumper at the trans relay.

Any help would be appreciated!!!! I've been dealing with this for far too long and I'm finally so close I can taste it!

Cheers!

Early 1996 doesn't work with a lockup switch until you have the dealer reflash the computer.
