The harness consists of 3 signal conductors and 1 ground wire.
BROWN wire is used for input DATA 1
YELLOW wire is used for input DATA 2
GRAY wire is used for input DATA 3
BLACK wire is used for ground.

2. Installation

The SBC I-D can read voltage between 0-16 volts. The numeric voltage reading can be displayed
on DATA 1, 2, 3. The data can be obtained from the ECU output or additional sensor outputs such
as the "Blitz" Air Fuel analyzer. You may connect the yellow, brown, or gray data wires to the
output signals with the splice or the wire tap set. Use the ground eyelet for the black ground wire.
