TQ lock up mod
Sorry, but the search is not working. this comming week im planning on doing the EBPV brake an TQ lock up mod. Im planning on using an on/off switch with 4 pins, an having one side make the ground connection for the TQ an the other side send the reduced 12v to the EBPV solinoid. what im looking for is the wire/s that i need to find an ground for the TQ and where they are located. this is a late 99'. thanks

According to the data recieved on the forums, On the drivers side fenderwell under the brake Master cylinder you will find 3 to 4 connectors. 3 black and one gray. You want the gray one pin number 6 violet with yellow tracer, The side leading to the transmission. Good Luck make sure you do it in the light and get the RIGHT wire,

Wiring question? can you use a lighted switch on this mod? If so how is it configured? I found the purple/yellow tc wire and can make it engage but the switch is throwing me. Guzzles diagram doesnt provide the switch schematic maybe I just blind

If you want to be able to see when the PCM locks up the TC, you will still need an external LED indicator.
Most lighted switches have 3 electrical connections on them (SPST)
One marked battery (+) which would connect to the +12v part of the circuit, in my schematic it would be wherever you are picking up the 12v switched voltage.
One marked accessory (+) which on my schematic would be the relay.
The last terminal marked Ground (-) which would connect to chassis ground.
Whenever the switch is flipped, both the relay and the internal LED in the switch are turned on. When the switch is turned off, both the LED and relay are taken out of the circuit.
