Andrew,
I just emailed the installation instructions and pinion position diagram for the Doromatic Falcon 1990. They should be the same as the 990.

Robert,
I am emailing the 990/1990 installation instructions through my Robert Brooke Email.
Greg
The Doromatic Falcon 990/1990 can not be converted to Electric Latch Retraction. But what you can do is switch over to the 1690, or the EL1690, which uses the same concealed rods. The EL1690 can be found on our website @ Doromatic Falcon EL1690
Greg
Brad,
I will email you the installation instructions, that will hopefully help. It has to do with the position of the Cam on the Retractor, the instructions will clear it up.
