I used the location of blackout toggle switch on the dash board so everything looked correct.

All good points. And as the blackout switch is pretty much defunct, repurposing it is a good idea. Thanks for sharing your thoughts, folks.

Is there a maximum pressure I can go to for the electric pump, so as not to damage anything on the existing mechanical pump? The manual says 3-3/4 lbs, so I presume this shouldn't be exceeded?
