ENGINE REWORK - Refer to Illustration 1
1. Remove the 2 clamps and the Intake hose from the turbo to intake elbow.2. Remove the injection line clamp and remove the 4 bolts that secure the intake elbow to the intake manifold and remove the elbow. Remove the old gasket and clean the surface of the intake manifold.3. Install the 5M6214 plug into the side of the 166-6115 Elbow.4. Install the 517678 Gasket and 166-6115 Elbow on the intake manifold with two 6V3940 Bolts (short) and two 5P8347 Bolts (long). Install the injection line clamp and secure it to the 116-6115 elbow.5. Place the 5I7677 Gasket and heater assembly on the 5I8021 Elbow. Check that the airflow direction arrow located on the terminal stud side of the heater assembly is pointing down toward the intake. Also make sure the Power and ground studs are facing to the rear of the machine.
6. Place a 5I7678 gasket on top of the heater assembly.7. Install the 166-6113 Hose and clamps loose on to the 5I8021 elbow.8. Install the 166-6113 Hose and elbow assembly to the turbocharger and heater assembly.9. Secure the 5I8021 elbow and heater assembly with four 5P8347 bolts and tighten the hose clamps to the elbow and turbocharger. Secure the heater assembly ground wire with one of the bolts. Check for Continuity from the ground stud on the heater assembly to frame ground.

Cut the short section of wire off of the harness that goes from terminal R1 to R2 and discard. Tape off any exposed wiring. Connect the 310-PU to terminal R2. Before modification the 310-PU is used to engage the glow plug relay. After the modification the 310-PU wire will be used to trigger the 104-3204 controller to go into a post heat timer function when the starter motor is engaged.
2. Install the 4I3166 Key Switch Panel. RELAY PANEL - Refer to Illustrations 3. 4. 5, and 6
