Electrical connections VSI-I wiring harness

grey-white Make a connection to ignition + / contact +.
Make sure that the voltage will not fail during starting the engine.
orange For the measurement of the lambda signal of cylinder bank 1.
Connect the wire parallel to the lambda sensor signal wire.
orange-white For the measurement of the lambda signal of cylinder bank 2.
Connect the wire parallel to the lambda sensor signal wire.
purple-white For measuring the engine speed.
Connect to a Hall-sensor or camshaft sensor,
Make sure that the squared signal is not higher then 30 Volt !
Never connect to the ignition coil (only with a RPM module) !
Bicolour / For measuring / interrupting the petrol injectors :
Full colour
Interrupt each petrol injector control wire ( injector min )
Each VSI wire has a cylinder number printed on the wire, connect
this wire to the corresponding petrol injector.
Connect the bicoloured VSI measuring wire to the ecu side,
( wire code: ECU SIDE ).
Connect the accompanying full coloured VSI wire to the
petrol injector side ( wire code: MIN INJ SIDE ).
See diagrams in Installation Manual General part 1 / 2.
Attention:
Each bicoloured measuring wire corresponds to a specific
LPG injector and cylinder number. Do not interchange the
wires.
