SprinterArmor™ Ignition Module Protection Shield

Installation Manual

Purpose

The SprinterArmor™ Ignition Module Protection Shield is designed to protect the factory ignition (EZS) module from water, moisture, and condensation — common causes of corrosion and intermittent electrical faults.

This shield provides a durable, sealed, OEM-style solution without modifying the vehicle.

Tools Required

• Torx T25 screwdriver
• 10mm socket and ratchet
• Phillips #2 screwdriver
• Trim removal tool or small flat plastic pry tool
• Clean rag (recommended)

Estimated Installation Time

15–20 minutes

Installation Steps

Step 1: Power Down the Vehicle

• Turn the ignition off.
• Disconnect the negative cable at the factory disconnect point (VERY IMPORTANT).
• Allow the vehicle to sit for at least 5 minutes.

Step 2: Remove the Lower Dash Trim

• Locate the driver-side floor covering holding bracket. Remove the two (2) Torx T25 screws, then remove the driver-side factory floor covering.

• On the lower left side, locate the plastic panel that covers the left A-pillar and wheel well area (this panel includes the hood release handle).
• Unscrew the hood release mechanism by removing one (1) T25 screw.
• Remove the lower far-left dash panel.
• Remove one (1) T25 screw from the OBD port/hood release cover panel.
• Disconnect the OBD connector by clicking it out.
• Gently pull the panel to the right to release it.

Step 3: Locate the Ignition (EZS) Module

• The ignition module is mounted on the wheel arch support panel, secured with two plastic nuts. It has blue and white connectors attached.
• Gently and carefully release the connectors from the module.
• Use a plastic trim tool to pry the plastic nuts (along with the module) off the welded studs.

Step 4: Install the SprinterArmor™ Protection Shield

• Position the shield base over the ignition module.
• Ensure the wiring passes cleanly through the designated opening.
• Seal both wiring harnesses (just after the connectors) with the supplied flexible rubber electrical tape — gently wrap around and squeeze to seal.
• Position the ignition module inside the shield. Pay attention to alignment — the module should sit flush around the edge of the shield.
• Install the cover and gently press it in so the alignment pins seat correctly.
• The flexible TPU seal should compress slightly, forming a moisture barrier.
• Once the back cover is installed, install and position Water Shield on top of the module and align it with the top hole 

• Install the supplied screw using a Phillips screwdriver.
• Install the ignition module assembly back onto the vehicle:
  • Align the connectors with the blue connector side facing down and the white connector side facing up.
  • Align the top blue connector wiring alongside the Water Shield Guard
  • Route the wiring alongside the nearby CPC module.
  • Install two rubber tape seals right on the studs, secure the Shiueld with two 10mm nuts on the corresponding studs using a 10mm socket.
• No excessive force should be required.

Step 5: Verify Fitment

Confirm the following:

• The shield is fully seated
• Wiring is not pinched or strained
• All connectors remain fully engaged

Step 6: Reinstall Trim Panels and Floor Mat

• Reinstall the lower dash panels.
• Tighten Torx screws snugly (do not overtighten).
• Reinstall the hood release mechanism.
• Reinstall the driver floor mat.
• Reconnect the ground cable at the factory disconnect point.

Step 7: Final Check

• Start the vehicle.
• Confirm normal ignition operation.
• Verify no warning lights or error codes appear.

Installation is complete.

Notes & Recommendations

• Verify the blue TPU gasket sits correctly in its designated grooves before installing screws.
• Verify Water Shield is correctly positioned and aligned properly. 
• Check for mold or corrosion on the ignition module connection points. Clean any mold or rust before reconnecting.
• If an alignment pin is damaged during installation, the shield will still function correctly. The pins are used for positioning only and are not structural.
• Don't forget to wrap the cables with the supplied flexible electrical tape.
• Don't forget to install rubber pads on studs before installing nuts to secure the module.
• Do not overtighten cover screws or stud nuts.
• This product protects the ignition module from moisture exposure but does not repair existing wiring damage or active windshield/body leaks. Any ongoing leaks should be addressed separately.
