1997 Fleetwood Bounder - BCC

Trying to clean up the previous owner's shortcuts. I'd like to find out where the black wire from behind the chassis isolator goes. It's a p30 chevy chassis, gas. the board is a CB-115 Rev A. A picture or schematic of the wire placement, in general, would be really appreciated also. Thanks in advance for any advice.
