On my R4 I have lockup on a switch and it does the job.
I know there is a way to add in pressure switches and daisy chain them to lock and unlock on its own. Do you or someone else on here have a wire diagram for this so I can make my own harness?

It easy there's already a 4th gear pressure switch in the pan in the valve body. Supply 12v to the transmission,use the existing 4th gear swich to turn on and off the lockup solenoid. Just look at the 4th gear switch as if it was a toggle switch that turns on the lock up solenoid in 4th gear. Interrupt the 12v supply with a toggle if you want the option of disabling lock up.
