Engine Harness
Engine harness.
1. On the passenger’s side, the engine harness begins in the passenger foot box. The computer plug is
pushed through the oval shaped hole on the passenger’s foot box top from the engine bay side.
2. Attach the computer to the underside of the top of the passenger foot box using the plastic bracket
from the Mustang and the screws provided. Alternatively the computer can be mounted to the inside
of the firewall provided the optional heater/defroster is not being used.
3. Use the drilled holes and cable tie trick to hold the extra harness to the top of the passenger foot box.
4. The harness splits into two on top of the foot box. The short, smaller harness goes forward and
connects to the mass air sensor and to the harness on the engine for the O
2
sensors and oil level
sender. The other larger bundle goes along the firewall and contains the vacuum control lines for the
EGR valve and engine, the connector to the distributor, the two large plugs for the fuel injectors, the
to the dash harness connectors by the master cylinder, and the coil plug.
