B&M makes a lockup kit that has the lockup speed adjustable. Take Screamer's advice......dont run it without a lockup!!

Also, you must have the brake switch hookup. Your truck already has the switch. The switch is down by the steering column. It has two sets of contacts, one for the brake lights and one for the converter lockup. The brake light circuit is normally off and the converter circuit is normally on (both with the brake pedal up).

The B&M kit was also cheap and included the trans connector.
