Please educate me about the tcc Despite my best efforts, I'm still completely in the dark concerning the TCC, how it works, what activates/de-activates it. I have the TCC switch, but I have no clue where to wire it in. This is a new build, PSI stand alone engine/PCM harness, which also has trans connections on it, custom body/cabin harness and fuse panel. new build 4L60e. This is the switch that I have. https://secure.ultracart.com/catalog/PSI/KIT-1002.html
Thanks

Thanks, the directions I got with the switch says to hook one wire o ground and the other to the TCC circuit wire. I can't figure out where that wire is.
If you are rigging an external control you need two
things. One, the TCC enable switch (short to GND
= on). Two, the TCC PWM needs 12V or close to it,
you have to energize that valve or you get 0% of
"whatever the main line pressure is".
