WIRING THE BREAKOUT BOARD—WITHOUT THE EDDY CURRENT BRAKES

1 Attach the pickup card cable (B, C) to the Breakout board. This cable may already

be connected.

The pickup card cable (B) from the stationary dyno has four wires which connect

to the wiring block labeled DRUM 1.

The pickup card cable (C) from the 4WD dyno has four wires which connect to

the wiring block labeled DRUM 2.

2 Attach the brake signal cable (D) to the Breakout board. The brake signal cable

from the 4WD dyno has two wires which connect to the wiring block labeled

BRAKE.

Note: There will already be wires connected to BRAKE; add the brake signal wires

to this location.
