[Leverhead]

The toggle would be inline (mounted in your cab) with a 12V wire going to one side. Toggle 'on' would supply 12v from the other side of the switch to the lockup circuit (one side of the pressure switch) via the external connector into the trans pan. The extra 2 terms on the brake switch would be wired after the toggle and would be an interrupt of the 12v when you press the brake to disconnect the TCC. The 12v carries on from the opposite side of the pressure switch to the lockup solenoid. The black wire from the noid would come back thru the connector to ground. The bowtie overdrive kit looks all inclusive although you could get the individual parts separately on an as needed basis if you wanted.

Pressure switch is Ac Delco 8643710
Brake switch is Standard products SLS110
External trans connector with pigtails is Napa EC79

Don't know the# for the solenoid as I used the one that was in the trans.

This is just one way to wire it....some diagrams have it ground switched. Some (like mine) use a vac switch to trigger the 12V 'on'.

Its a good idea to connect a small indicator light to the lockup circuit also.

Hope this helps.
