BCM for GM - DIP SWITCH Settings

The Z-Flash BCM for GM features a total of six DIP Switch settings on the back of the unit.

Please note that any changes made to the DIP Switch settings has to be done while the module is plugged into your vehicle and when the vehicle is running.

If anything is changed prior to install the changes won't go into effect.

Below is an overview of each DIP Switch Setting on the Z-Flash BCM for GM:

DIP Switch #6 has to remain off unless you are told otherwise.

The other DIP Switches are completely optional. However, we normally recommend to put DIP #5 ON because this allows more of a consistent pattern. If Strobe Mode is on there will be a delay of a few seconds between flashes.
