ECU Wiring Harness Installation

Route the violet power wire to a switched 12V power source on the fuse panel (See Photo 1, below). NOTE:

This requires a male fuse extension (not supplied) (See Photo 2, below).

Plug the main wiring harness into the ECU (See Photo 3, below).
The correct ECU harness installation locations are shown in Figure 1, below.
Peal the backing from the Velcro, and mount the ECU behind the dash next to the glove box opening (See

Photo 4, below). NOTE: At this point, reinstall the speedometer cable and plugs into the instrument

cluster and install it into the dash with the OEM hardware (See Photos 5 & 6, below).
