Dick,
I do not know anything about the wiring in a 2007 Contessa. It may help others who might be familiar to clarify what relay was replaced and why, that was located in the rear compartment.
When you say "wiggle the battery cut off switch", do you mean you toggle it on and off or do you physically wiggle the switch meaning you might have a loose connection on the backside?
You may want to clarify for the lights staying on if they are 120v, 12v, and if they are on a multiplex lighting system or not.
