Conn 580 to Leslie 700 Hookup

[Royal]

I just bought a Leslie 700 and would like to hook it up to my Conn 580. As many of you know the 580 is a two channel organ and the 251 Leslie is recommended, - but I can't afford one (and my wife says that it is too tall to go in our living room). So here I am with a Model 700, an admitted step down. Is it possible/advisable to just re-wire the 9 pin leslie cable such that the tibias go to the rotary, complex to the stationary and then by adding a DPDT 110vac relay in the leslie cabinet go straight to theleslie motors? It appears that the Leslie 700 wants a grounded signal to switch speeds on the motor.I would essentially bypass the electronic speed control in the leslie by simply unplugging it. This would leave a few unused wires in the leslie cable for spares. Am I missing something here. Do I really need a 7660 hookup kit? If I don't buy the 7660 kit, what is it thatI lose if I did it as above?

Thanks in advance, Roy

Details on the 7660 kit are here:

but there's no full schematic.

You could certainly route the audio to the correct pins for the 700, but would it not be better, rather than modifying the leslie, to make a small relay board that goes in the organ, taking the switching voltage for the 215 and using that to power a relay that could give the 700 the appropriate grounds it needs to switch speeds.

Remember that this method won't give you main/echo switching, but the 7660 wouldn't do that either. If you want that, you can buy or make up another kit that would incorporate this switching. Can't remember the model number of the kit right now, but we did discuss this and find the solution on the Hammondzone Yahoo group a few months back.
