engine running signal

[MrMPuk]

From looking at the drawings I think it would be quite hard to do without invalidating you warranty but I know from looking into fitting these to cars before that the manufactures generally make a piggyback plug that goes in between the engine management system and vehicle harness. So I'd say your best bet would be to contact the tracker manufacturer and speak to them, if they dont make a connector they will be able to tell you where to wire it up as they do it everyday!
