Iam removing the datatool immobilser from my 1999 mille, a bit stuck, removed most of the immobilser wiring and repaired original wiring, however the immoboliser wires join to a pair of blue / grey wires on a black / white connector this is located between the ECU and relays. The blue / grey wire comes from the right hand side of the frame, through the connector then off to one of the relays, after removing black immobilser wiring not sure where the two blue/grey wires coming out of the connector go to, advice would be appreciated.
