Since this is a new cam breakin & there are wiring issues first if there is any doubt that it is wired incorrectly I'd remove the harness under the hood to the ign & jump fire to the ballast/coil/ECU/ecu connected to dist (zigzag 2 wire connector) with jumper wires solidly connected to them then start it by jumping the starter relay to complete the delicate/critical cam/ring breakin process & get that out of the way. If you hookup the nonralley harness & every connection that needs fire is correct then yes that would work. #1 #1 with this being a cam breakin it needs to fire off immediately & whatever you need to do to insure that happens & you want that confirmed before/without cranking the eng
