    Just hook up wires to positive & negative terminals on engine block. Do not have to be batt. cables unless you want to do a compression test. Then unplug 2 wire connector at alternator. Stick a stripped wire into purple side of that harness. Then back to positive side of batt. when you hear fuel pump come on you,re good. If YOU want to do compression test, use batt. cables. Almost forgot, unplug fuel pump if fuel system is dry.
