TCC/Brake Switch Signal - what does it do?
I cut this wire wile removing wires for race wiring. Does this affect anything besides cruise control. Is this wire needed for anything else? This is the only TCC wire I cut.

There are two Connectors on this Switch, that two-wire Connector on that Switch goes directly to the PCM. There is a PINK 12v IGN coming into it, and a BLU/BLK STRIPE wire coming out going to the Dash Connectors under the Passengers Kick Panel and eventually to the PCM. This is what UNLOCKS the Convertor when you hit the Brakes. If you have this cut, the Convertor will never lock, since the circuit is broken.
The Cruise Switch is a seperate Switch on the Pedal above this Switch.
