1999-2007 INSTALLATION GUIDE GlowShift.com © GlowShift Gauges, LLC | All Rights Reserved 2 FORD SUPER DUTY 7.3/6.0 POWER STROKE B. INTAKE AIR HEATER PLUG INSTALL (7.3 Only) 1. Locate the Intake Air Heater (IAH) on the cold side of the intake manifold on the passenger side of the vehicle. 2. The wire that runs from the IAH down to the solenoid is the main power wire for the IAH element. Using a 13mm wrench, remove the nut and washer from the solenoid and disconnect the power wire from the solenoid. Note: Ensure that the additional power feed wire that is not connected to the IAH is installed back onto the solenoid and secured with the washer and nut. 3. Using a 10mm wrench, remove the captured nut and power wire from the stud on the IAH. Once this has been removed, you can remove the power wire from the IAH. 4. Remove the ceramic insulator from the IAH and set the stud aside. Then, remove the ground wire from the IAH. 5. The ground wire coming from the IAH connects to a grounding location under the intake manifold. Use a 13mm wrench to remove the retaining nut and disconnect the ground wire. 6. Use a 1” wrench to remove the IAH assembly from the intake manifold. 7. Thread and tighten the IAH Delete Plug into the intake manifold using a 1 1/16” wrench. Note: Do not overtighten. 8. Take the included brass compression fittings and wrap the 1/8-NPT male thread with Teflon tape to ensure a leakfree connection. Insert the included boost hose into the thread connected to the T-fitting with a 12mm wrench and an 11mm wrench. Using a 3/8 wrench, tighten the compression fittings until the line is snug. (Reference diagram on page 1) Note: Do not over tighten. 9. Route the boost line 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. C. DRILL & TAP SPYDER (7.3 Only) 1. Using an 11mm deep socket, remove the intercooler pipe. 2. Place a vacuum inside the intake spyder to prevent shavings from entering the intake during the drill and tap process. 3. Mark the planned drilling location with a center punch. Starting with a 1/8” drill bit, drill a pilot hole into the manifold and gradually step up in drill bit sizes until size R is reached. 4. Now that the hole is drilled to size R, clean the manifold with a vacuum to ensure no shavings are in the manifold. B6. B7. B8. C3.
