4.3 knock sensors
 

I have a 2001 Chevy Blazer and dropped a 1997 4.3 vortec back in to it and am having an issue with the knock sensor. The 2001 wiring harness has a 2 prong plug whereas the 1997 motor uses a sensor using a single wire. Was needing to know if there is a pigtail adapter of some ilk or what must be done to rectify the problem. Thank you in advance my friends.
