Installation
Installation of the Subaru H001SAJ800 Remote Engine Starter involves accessing the vehicle's dashboard and steering column wiring. It is crucial to follow the specific steps for your vehicle's ignition type (Push-to-Start or Key Start).
General Disassembly Steps:
- Turn on the vehicle's engine to allow free rotation of the steering wheel.
- Unscrew and remove screws behind the steering wheel.
- Use a pry tool to unsnap the lower steering wheel column cover.
- Unsnap the instrument cluster cover and remove any connectors on its backside.
- Remove screws on the top and bottom of the instrument cluster, then pull out the instrument cluster and disconnect its connectors.
T-Harness Connection:
The T-harness connects in-line with existing vehicle connectors. Specific connections vary by vehicle model and ignition type.
- For Push-to-Start vehicles, connections are typically made at the keyless access ECU. Remove the top 30-pin connector and the bottom 28-pin connector from the module, then plug the T-harness labeled 'A' and 'B' in-line respectively.
- For Key Start vehicles, remove the white 8-pin connector from the ignition switch and plug the T-harness in-line. Connect the grounding ring to the vehicle's chassis using a metal screw.
- Locate the vehicle's fuse box under the driver's side dash. Remove the white and brown connectors to access required connections.
Installation Type Determination (Key Start Specific):
For Key Start vehicles, there are two possible installation methods based on the 20-pin gray connector on the back of the fuse box:
- Installation Type 1: If pin number 14 (blue and white wire) is populated, only the immobilizer T-harness will be used. Plug the immobilizer T-harness into the black connector on the main T-harness.
- Installation Type 2: If pin number 14 is unpopulated, only the immobilizer cable will be used. Locate the red and white wire at pin number 36 on the 84-pin junction connector behind the fuse box. Cut this wire in the middle, strip back the jacket, and connect the yellow wire from the immobilizer cable to the vehicle side of the red and white wire, and the red wire from the immobilizer cable to the connector side. Cover exposed wires with electrical tape. Plug the immobilizer cable into the black connector on the main T-harness.
Use the provided zip ties to secure the module and wiring, ensuring no components interfere with moving parts or pedals.
