We need help too

Does anybody know how to hot wire the Parker-Racor 90S1230C fuel/water separator integrated assembly. Our units control and/or pump is tango uniform.
We have a new to us 99 Exec. w/M11. It has a Parker-Racor 90S1230C fuel/water separator integrated assembly w/RK12963 retrofit kit. It does NOT purge or prime anymore. I changed the filters, S3230P & 300200, then went to purge it of air with its integrated pump, but the pump doesn't pump. I don't know how long it has been broke. The power lite comes on w/the ignition key, then when I push the air purge button, the amber lite comes on, but nothing happens. After about 20 seconds, the amber lite goes out. When I push the H2O purge button, no lite, no pump action, nothing? My local Parker-Racor dealer advised me that the purge pump and control panel are obsolete and no longer available. He suggested I purchase either a Parker-Racor 790R with electric prime pump for $350, or the 460R w/manual prime pump for $200. Neither one of these units uses the S3230P filter, which I have 2 of.

What I would like to do, but don't know how to do it, is remove the control panel, and install my own switch to turn the prime/purge function on and off, that's assuming the pump is operable. One of the control panel pig tails has 2 wires, and the other has 6. Can anybody be of help, please, before I spend a bunch of money, again.
Thanks
