Ford Wiring Codes
- Attach all sensors on Loom
- Connect Purge Valve to plug near computer is does not need
vacuum but needed to keep fault codes clear
- The red wire is the main 12 volt feed wire and will require
further heavy wire to the battery or isolator switch, connect Earth, put an earth on Fuel Pump
- Connect up heavy wires to Starter and alternator, not
SUPPLIED
- Earth to engine OR CAN BE TO BATTERY
- Connect Brown or Blue Plug to Ignition coil
- It is Recommended to use an isolator Switch or Disconnect
Battery OR Computer with not in use
- Set Timing using Computer switch to give base timing of 10
degrees, this only happen for about 2 minutes then it goes back to computer control
- Check Codes by starting the engine and the turning on
the Computer Switch, all of the codes as per Ford Factory are available
