Installation Instructions
HIGH IDLE THERMACTOR AIR BYPASS KIT E3TZ-9000-BINSTALLATION INSTRUCTIONS
1985-1/2 - 1987 VEHICLES
1. Install solenoid (E1ZE-12A170-B2A) (Item 1) in a suitable position (on E-Series vehicles, a potential mounting place is at the rear of the engine or cylinder head) with the valve positioned as near to vertical as possible to assure positive function. Rework the bracket if necessary to facilitate mounting.

2. Find the Idle Vacuum Valve (IVV) which is located between the rocker arm cover and the choke side of the carburetor (See Figure 1). Remove the vacuum line from the larger diameter port of the IVV. (See Figure 2).
FIGURE 2:
3. Insert the large end of the reducer (383004-S) (Item 5) into the vacuum line removed from the IVV. Then insert the small end of the reducer into the 3/16 inch vacuum line cut from the bulk hose supplied. Extend this line to the solenoid, cut to fit, and install on the solenoid metal port (See Figure 2).
4. Using bulk 3/16 inch vacuum hose supplied in the kit, attach the end of the vacuum hose to the larger diameter port of the IVV which is perpendicular to the valve and marked "VAC." Extend this vacuum line to the solenoid installed in Step 1, cut to fit and attach the line to the plastic port of the solenoid (See Figure 2).
5. Attach the pigtail assembly (E7TZ-14A411-SO) (Item 7) connector to the solenoid installed in Step 1.
6. Determine the type of throttle actuator system used on the vehicle, then follow the appropriate wiring diagram provided. (See Attachments I or II). Use electrical connectors provided in the kit.
Vortec system requires relay (E3TB-9345-AA) (Item 8) and pigtail assembly E7TZ-14A303-SO (Item 9) provided in the kit. Mount the relay in suitable location under the instrument panel.

7. Remove and replace the three (3) thermactor check valves with a new level of valves (E8TE-9A487-BA) (Item 2). (See Figure 3.)
8. Continue with instruction step 21 (Page 22) of Kit E5UZ-9000-A. Verification of high idle thermactor air bypass operation will be checked after Kit E5UZ-9000-A installation is completed.

PRE-1985-1/2 VEHICLES
If the vehicle is a pre-1985-1/2 model year, the production -9B289- thermactor air bypass valve must be removed and replaced.
1. Install the new thermactor bypass valve (E1ZE-9B289-BA) (Item 3) (See Figure 4).

FIGURE 5:
2. Install solenoid (E1ZE-12A170-B2A) (Item 1). Mount the solenoid in a suitable position (on E-Series vehicles, a potential mounting place is at the rear of the engine or cylinder head) as close to the choke side of the carburetor as possible. The valve should be positioned as near to vertical as possible to assure proper function. Rework solenoid mounting bracket if necessary.
3. Route the existing vacuum line to the bottom port of the new bypass valve (See Figure 5).
4. Using 3/16" vacuum hose provided in the kit, route a vacuum line from the plastic port of the solenoid to the top port of the bypass valve (See Figure 5). Install a 5/32" rubber cap. (Part No. 382444-S) (Item 6) on the top metal inlet port of the solenoid.
5. Attach the pigtail assembly (E7TZ-14A411-SO) (Item 7) connector to the solenoid installed in step 1.
6. Route and connect necessary electrical wiring based on the type of throttle actuator installed on the vehicle. Refer to the appropriate wiring diagram attached (Attachment I and II). Use connectors provided in kit.
7. Continue with Page 12 of Kit E3TZ-9000-A Verification of the high idle thermactor air bypass operation will be made upon completion of Kit E3TZ-9000-A installation.

INSTRUCTIONS
1. Locate Vortec vacuum actuator (left rear side of engine behind carburetor throttle lever.)
2. Follow vacuum line from Vortec throttle actuator back to Vortec solenoid.
3. Disconnect the two wire leads from the Vortec solenoid and connect them to the red and black wires of Ford wiring E7TZ-13A303-SO (Item 9) and relay E3TB-9348-A (Item 8) using butt connectors. Relay is to be located under dash panel. Route wires from relay harness through engine compartment before making connections.
4. Connect the red wire from Ford solenoid harness installed in Step 5 to one of the terminals of the Vortec solenoid.
5. Splice the white wire from the relay harness (Item 9) to the red wire from the Ford solenoid (solder and tape).
6. Fabricate a ground wire for the other terminal of the Vortec solenoid and ground to the engine.
7. Ground black wire of Ford solenoid to engine.
B. Route purple/orange wire from relay harness (item 9) to fuse panel area. Locate purple/orange wire from fuse 11 and splice into purple/orange wire from relay harness. (Solder and tape).
