Dual Fuel on a '88 F250
 

I just purchased an '88 F250 4X4 351 5spd that has a full propane conversion, for greater flexibility I would like to convert it to dual fuel. The installer used an Autotronic 5910 Dualcurve and I am looking for info from anyone that has expirience with these units.
From what I can see on page 7 of the installation manual:

all I need to do is wire in a switch and I should be already to go, can anyone confirm or add to this.
I was also thinking that as these unts are no longer available new maybe I should try and find one or two extras in case my dies.

Thanks, Greg
