Does anyone know where (& how much) to buy the harness to hook up to the power valve motor for adjusting?

you dont need it. Open the powervalve servo cover, and either with the choke or the idle screw get it the sled to idle under 900 rpms (which is where the valves automatically open for the self cleaning feautre, and as soon as you see them open all the way shut the ignition off. Mark the servo wheel and the housing so you know the servo position that is all the way open, so that if you accidentally turn it at all, you can turn it back to position by hand.
