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).
