1992-1997 INSTALLATION GUIDE GlowShift.com © GlowShift Gauges, LLC | All Rights Reserved 2 FORD F-SERIES 7.3L POWER STROKE Pyrometer/EGT Gauge Installation SECTION 2 Optional: Safely jack up the truck for easier access to the driver’s side exhaust manifold. 1. Take necessary safety precautions to confirm that the exhaust is sufficiently cool during this process. 2. Using a center punch, mark the location where you are going to drill a hole for the EGT probe on the manifold. 3. The hole’s location should be on the bottom side of the driver’s side exhaust manifold before the up-pipe leading to the turbo. 4. Starting with a 1/8” drill bit, drill a pilot hole into the exhaust manifold. Continue increasing the size of the pilot hole using various drill bits until you reach size R. Using cutting oil, tap the hole to 1/8-27 NPT. 5. Ensure all shavings are out of the manifold by periodically using a vacuum and a pen magnet to remove them. Warning: Failure to remove metal shavings can result in possible engine damage. 6. Apply a silver grade anti-seize to the threads of the EGT ferrule fitting and thread the fitting into the exhaust manifold. Tighten the fitting with a 14mm wrench. 7. Install the gauge’s EGT Sensor into the Ferrule Fitting Adapter, ensuring the sensor is positioned approximately halfway into the manifold. Tighten using a 14mm wrench. Note: Do not overtighten the ferrule fitting. 8. Plug the EGT Sensor Harness into the EGT Sensor. 9. Route the EGT Sensor Harness to an opening on the firewall on the driver’s side of the engine bay and use zip ties to secure. Make sure there is no contact with any direct heat source or moving parts of the truck. Optional: Lower the vehicle if it was raised. 4 a. 4 b. 7.
