I have disconnected the factory radio and ordered a GMRC-01 with a factory connectable harness, but I'm not sure where to tie the accesory switch line into for the chime unit. I've tracked down all the wires in a repair manual wiring schematic, but I don't want to interfere with the data bus by tieing into the wrong line, which line do I tie into?
How do I install the GMRC-01 in a 2001 Pontiac Sunfire?
