Plug & Play, BCM-Controlled, OE Light Flash Module
ZW-GM
T-Harness
I/O Button Harness
(optional use)
Thank you for purchasing a genuine Z-WAGZ unit, the simplest BCM-module for flashing OEM lights with a press of a button. This unit comes pre-programmed with 8 different light patterns, some for halogen systems & some for LED systems see below for full operation information including on-board LED status.
Operation for all GM vehicles is the same:
1. Install the Z-WAGZ unit to the OE BCM unit. Follow instructions on page 2 for all vehicles.
2. Turn Ignition ON (Ignition must be on for proper operation). Leave vehicle in Park.
3. To activate Z-WAGZ:
- Press and HOLD the high beam lever (5 sec) OR
- Press and HOLD the provided push button (3 sec) OR
- Send a latched 12v (+) signal to the blue wire (designed to be extended for OE up-fitter switches)
Pattern 1 will begin to flash. Once pattern 1 begins, the hazards in the gauge cluster will blink 1 time, indicating Pattern 1 has been selected and the LED on the unit will blink BLUE. See chart for remaining pattern color indication.
4. To switch to Pattern 2: (Pattern 1 must be currently active)
- Engage either turn signal, then press and HOLD the high beam lever once more (5 sec). OR
- Press & release the provided push button
The hazards will blink twice indicating Pattern 2 has been selected. Repeat this process to switch to the next pattern.
5. To deactivate Z-WAGZ:
- Press and HOLD the high beam lever OR
- Press and HOLD the provided push button OR
- Release 12v (+) signal to the blue wire (if connected this way)
NOTES:
- Vehicles equipped with LED lights should use LED patterns. Vehicles equipped with standard bulbs should use bulb patterns.
- Not all lights on the vehicle are necessarily used, some lights are not controllable via BCM CAN data.
- Z-WAGZ will retain the last used pattern, even after being disconnected from the BCM (if ever).
- When flashing is active: turn signals, headlights & reverse lights will override pattern flashing, until turned off again.
- When on some patterns, in some vehicles, the reverse camera image may show up/flash on the OE screen (if equipped). This is a factory limitation and is normal. If you want to avoid this, keep DIP (3) OFF.
- ‘Plow Mode’, when active (INPUT 2), disables High & Low beam flashing and slows the pattern down so that the relay box (plow module) can keep up with the flashing (prevents overheating).
GM Vehicle Installation
- Locate the BCM unit. The chart below indicates the BCM location in various vehicles.
- With the vehicle OFF: disconnect the (4) highlighted plugs shown. Connect the male side of each T-Harness to the BCM and the (removed) plugs into the female side of the Z-WAGZ BCM harnessing. These connectors can only fit in one place and connect in one way and are color matched to the OE plugs.
- Connect the Z-WAGZ BCM unit to the 22-pin connector, tie-wrap the unit to another harness if desired.
- Return to page (1) for operation instructions.

OE GM Body Control Module
*‘Plow Mode’, when active (INPUT 2), disables High & Low beam flashing and slows the pattern down so that the relay box (plow module) can keep up with the flashing (prevents overheating).
This should be enabled whenever a plow is connected.
- I/O HARNESS NOTES:
– OUTPUTS are 100mA MAX. Do NOT power anything requiring higher current with these outputs! Use relays or connect to trigger inputs only.
– RIGHT & LEFT OUTPUTS will mirror the OE RIGHT & LEFT lights respectively (when unit is active). - Leave these OEM plugs connected
- OE BCM Connectors white, blue, pink, gray (removed)
- 22-Pin (power/data connections)
- DIP Switches (options)

- USB (updates)
- 12-PIN push button

DIP Switch Settings, Extra Features
Located on the back side of the unit is a bank of (6) dip switches – you will need a pick-tool to adjust.
All dip switches are LIVE, do not unplug the module to adjust.
