Im putting an 03 954 engine in my sand rail. It came with the wiring harness but i need to know what it takes to make the engine run, i didnt get the ignition stuff (key, kill switch, etc.) I have been tring to go threw the wiring harness diagram i downloaded but cant seem to get anywhere. Im want ing to just jumper some of the wires instead of spending big bucks for the ignition. any help would be appreciated.
