Electrical connections VSI-2.0 wiring harness
Check and measure the wiring in case of changes in the cars wiring colours.
For measuring the petrol injectors :
Interrupt each petrol injector control wire (injector min)
Each VSI wire has a petrol injector / cylinder number printed on the wire, connect this wire to the
corresponding petrol injector / cylinder.
Connect the bicoloured VSI measuring wire to the ecu side, ( wire code: ecu side inj ).
Connect the corresponding full coloured VSI wire to the petrol injector side ( wire code: min inj side ).
Attention:
Each bicoloured measuring wire corresponds to a specific VSI injector and petrol injector /
cylinder number. Do not interchange the wires.
