Electrical connections VSI-I wiring harness
Check and measure the wiring in case of changes in the cars wiring colors.
13 IG grey-white Make a connection to ig / c.
Make sure that the voltage will not fail during starting the engine.
46 LAMBDA 1-L orange For the measurement of the lambda signal of cylinder bank 1.
Connect the wire parallel to the lambda sensor signal wire.
45 LAMBDA 2-R orange-white For the measurement of the lambda signal of cylinder bank 2.
Connect the wire parallel to the lambda sensor signal wire.
40 RPM 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 /
Full colour
For measuring / interrupting the petrol injectors :
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.
