where the harness plugs in to the multi plug . normaly the side away from inlet manifold. take air filter top part off then . should be able to see plastic covered loom very close to metal coolant pipe. lift it up wards and look underneath. should be obvious if that is fault. worked on this stuff 4 to many years.
