Need to find a wire....

[jeremysyty]

I am installing Boost Commander and I am trying to find a wire. One that tell the ECM the torque convertor is locked. I originally thought that ALDL port H would do the trick. It doesn't, it locks the convertor up permantly. Like a lockup switch. The BSTC must ground it out. If I switch it to and ungrounded arm it doesn't work either. Looking through pages of wiring schematics and going nutz.

Any help is appreciated.
Thanks,
Jeremy

The ecm "tells" the torque converter to lock. The torque converter doesn't tell the ecm it is locked. Did that make sense?

I believe the F terminal on the aldl is for the tc. H has something to do with ABS.

Maybe you are looking for the hot wire that goes from the brake switch to the tcc solenoid? It's purple.

Follow what Jim said.

The ECM will put the wire to ground. Set the Boost Commander to trigger off of a ground switch and T it into this wire. I have the full wiring schematic I used at home; once I verify this system works (system = my wiring schematic) I'll post it, or send it back to Bob Bailey to incorporate into his instructions.
