I'm doing a 4.3L engine swap from a 2002 S10 2wd to a 1999 Blazer 4x4. I need some information on the knock sensor. Can I just rewire the newer style connector to the Blazer's wiring to make it compatible or would I have to re-tap the bolt hole on the 02 block for the older style knock sensor? Any info would be greatly appreciated. Thanks
