I have an LS2 block with a 24X crank and am switching to a holley hp system. I got the 558-103 harness with the longer extension for the crank sensor on the front cover... but Im guessing I will have the wrong front sensor for the harness ... ? Which sensors will I need to make this work right ? If i just run the stock LS2 front sensor and program the system to see a 24X crank... will that read it ok ?

I keep reading something about having to switch the two outer wires on the front sensor ?... but since I have a custom system cant I just program whatever I need to make it work ? Or this harness will need the specific sensors for the wiring to go in at the correct points at the computer.....
