- Disconnect your vehicle's battery before installing your module. If your F-Series truck has two batteries, be sure to disconnect both.
- Open the fuse box panel located in the passenger side footwell to gain access to the vehicle’s body control module (BCM). See Figure 1 for location.
- Remove factory plug A from the BCM and plug in the Z-Flash plug A into that socket. Then plug factory plug A that you removed into the Z-Flash adapter plug A.
- Remove factory plug B from the BCM and plug in the Z-Flash plug B into that socket. Then plug factory plug B that you removed into the Z-Flash adapter plug B.
- Remove factory plug C from the BCM and plug in the Z-Flash plug C into that socket. Then plug factory plug C that you removed into the Z-Flash adapter plug C.
- Connect the remaining 10 outputs into their respective leads on the flasher module in any order. Make sure to match the two white plugs for power and ground. See Figure 2 for details.
- There are two ways to activate the module: with the provided switch or by hardwiring it into your own controller or the vehicle’s upfitter switch. See the chart below for instructions.
- After installing your Z-Flash module, reconnect your vehicle's battery.
| Plug the provided switch into the flasher and turn on to activate.
|| Locate the bag with the red wire (see Figure 3). One end has a 4-slot connector that plugs into the Z-Flash and the other end is bare wire that ties to a switch. If you need to switch patterns, simply plug the red momentary switch into the other Z-Flash port that takes the 2-slot plug.

| Figure 4: Resistors
If you have non-factory LED bulbs, or if you’re getting a hyper flash condition after installation, the resistors need to be installed on the lights that are having that issue.
| Figure 5: Red Jumper Wires
These are used when you want to disable certain lights from flashing.
| Figure 6: Fuse Wire
This fuse wire is not needed unless you’re hardwiring your module to an external switch.
