Step 32
–
The attached wiring diagram for installation of the AVO engine control computer. All
wiring joints must be soldered and insulated with heat shrink and high quality electricians tape.
Do not use add-on crimp connectors for building a bridge harness as they give unreliable
connections and can result in erratic operation.
NOTE! Some model cars have wiring colours that are different from what is marked on the attached
wiring diagram. Use pin position references for connection. Always verify with volt meter that the
correct circuits are being connected to avoid damage to the AVO / Stock engine control unit and stock
electrical system. If in doubt consult AVO Turboworld or seek advice of a professional auto
electrician.
Step 33
–
Run supplied vacuum hose from AVO engine control unit to inlet manifold through the
engine bay firewall. Tee into the stock fuel pressure regulator vacuum hose.
NOTE! The vacuum hose connection between the intake manifold and the AVO Engine control unit is
very important for correct operation of the turbosystem. Check to make sure that this vacuum hose is
not twisted, kinked, disconnected, blocked or connected to the wrong manifold fitting prior to starting
engine.
Step 34
–
Install supplied AVO fuel cut defender as per supplied wiring diagram.
