Z-Flash BCM for Ford Common Troubleshooting Tips
If you are having trouble installing the Z-Flash BCM for Ford, you've come to the right place.
Before proceeding, remember that if a plug is not fitting properly, do not modify, force, or alter the connector in any way.
If a connector does not fit, you are likely attempting to install it into the wrong location. Review the installation instructions carefully or contact Z-Flash Support for assistance
J7 Plug Not Installing
One of the most common installation questions we receive is regarding the J7 Plug, which is the smaller of the two Z-Flash connectors.
If the J7 Plug does not align or will not install, you may be looking at the wrong connector. The J2 connector located below the J3 Plug is not used for installation and is sometimes confused with the J7 connector.
The correct J7 connector is located at the top right corner of the BCM, directly above the fuse panel. Due to the way Ford positions the BCM in many vehicles, the top row of connectors is often hidden from view, making the J7 connector difficult to locate.
The J7 connector is the uppermost connector on the right side of the BCM. Installation space may be limited, but the connector will only install in the correct orientation and should not require any modification.
Refer to the diagram below for the correct J7 connector location.
Other Troubleshooting Tips
- When changing DIP Switch settings, please make sure the truck is running with the Z-Flash turned on as well.
- If headlights are not flashing, please make sure your auto headlights are off.
- If the pattern doesn't look consistent and has a pause, put DIP Switch #5 ON for a more consistent pattern.
- If your Brake Lights are not flashing, you might be on Pattern 5, which purposely has this feature. Change the pattern by holding the button down for 1 second.
- If your lights are still flashing slowly, it could be that you have Halogen bulbs and not LED. The only way to change that is to upgrade to LEDs.
If, for some reason, you are having any issues with the vehicle not starting, make sure that our Z-Flash BCM for Ford J3 and J7 Plugs are seated evenly and are all the way in. If you see a little bit of red on the front of the plug, that likely means the plug is not fully locked into the BCM.
