Revised Lockup TC Wiring

I had my lockup torque converter wired up as most do. Power to the solenoid thru the brake/cruise switch and a 4th gear pressure switch to lock up when in 4th. this setup caused a lot of lugging unless you really stepped on it to downshift to 3rd. With my new engine it was even worse. I installed a vac switch and electronic delay. What a difference!! Works much better now.
