I am looking for a wiring diagram for a 2011 FD226. There is a small connector with a reset button inline between the red battery lead and the selector that seems to be an undervoltage trip of some kind. It's rusted and I only get about 9VDC to the dashboard. Would like to remove it - any experience with what this device is for? The breaker resets on the dash are for overcurrent, so not sure what this is needed for. Appreciate any help/info.
