Ok so i havr a 92 chevy c1500 originally had a 4.3 v6 auto i recently spun a bearing so i did a motor swap to another 4.3 v6 manual (yes swapped my auto flywheel onto new motor) but this has plastic vortec valve cover and motor has balance shaft if that helps. My issue is my harness has only 1 knock sensor and the new motor has 2 one behind passenger side on the block and 2 by plugs 3 &5 (how do i wire in the 2nd knock sensor to a 1knock sensor harness can i just splice into existing knock sensor wire?) also since mine was auto can i use my old knock sensor and replace the new motors sensor by 3&5? Or can i just run 1 knock sensor my original sensor if i re use and replace in position stated above^ would it affect the motor?
