You have to be VERY careful attaching anything to the Alternator light. That circuit is the 'excitation' circuit for the alternator, and depends on the small current through the bulb to magnetically 'excite' the rotor so that the alternator will start charging, then the charge voltage takes over.
You can use a very small high coil resistance relay on that circuit to drive a larger relay though.
Best to use the oil pressure switch circuit to drive the relay though.
