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-lo ).
Connect the corresponding full coloured VSI wire to the petrol injector side ( wire code: inj-lo ).
