Oh details.

I cut one of EBPV lines going to the solenoid and run through my relay contacts. The EBPV works using oil hydralics but is actuated by the solonoid.

the coil of the relay is wired through the on/off switch and onto the IVS sw. When IVS is closed 12V is lost to relay opening the brake circuit.

I put fused 12v through the relay contacts as a source to actuate the solonoid.

installed on/off light.

For TC
The relay has two sides so I run a grounding switch through the relay to the P/Y wire out of the transmission. The color is actually lime green. The Torque converter locks when this wire is grounded. Normally the computer does it but the computer unlocks it as soon as you put on the brake. I keep it locked going down hills. When I hit the accel computer takes over.
