Step 2 Connect one end of the wire-wrap clock cable to the corresponding wire-wrap connector on the ECU module,
and the other end to the external source of the timing. Change the timing input to high-impedance (lesser or
greater than 3 ohms) using a jumper on the ECU module. Remove the P1 jumper of the BITS-1 to change the
top timing input, and the P2 Jumper of the BITS-2 to change the bottom timing input.
