Making Cables for my BCM Upgrade
When I upgraded the Body Control Module (BCM) in my Chevy Venture Minivan, I discovered that this "option" would need some cabling (wires) added between the BCM and the DRL (Daylight Running Light) module, Horn, and Security LED. I don't have the security LED installed, so I decided not to install that wire (yet).
wiring applies to 2001 model (and possibly above) GM Minivans. Year
2000 (and maybe below) use a theft deterrent relay to flash the parking
lights (see schematic at bottom). I believe the horn circuits are the
same, but have not verified this.
<-- DRL Connector 1 <-- BCM Connector 2
Wire # 2 (to beep
horn with remote lock)
