hello finally fitted my new(ish) engine (300 tdi) into my 96 disco, all wires an pipes connected to the correct places, but there is no power to the starter motor?? where does this black wire go back to? an does anyone know of any wiring diagrams? the only wires i've not connected are the 3 that went to my old injector pump an the 2 in the temp sensor that was in the old head,my disco has an immobiliser fitted (original one) would it be this?
