4.3 v6 knock sensor issues after swap

[Parking lot mechanic]

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?

Your computer only expects information from one knock sensor. Use the original sensor from your first engine, in whatever location is the most similar to your first engine.

Hope for the best.

update made a new thread but the original one didnt fit in the new block as the threads were alot smaller in diameter to the sensor replaced it with part # su1124 from auto zone and plugged sensor in definitely brought it more to life but not having the 2nd sensor i feel is why my trucks still not running properly still slow on accel so just plugging it in and hoping 1 sensor wouldnt be an issue unfortunately didnt work original motor was a 92 tbi new motor is a 94 vortec tbi all sensors have fit exactly how the old motor except missing one knock sensor sensor on factory 92 harness

Did you check fuel pressure?

All the normal "tune-up" items usable and in place?

Connect a scan tool, look at the data stream.

I havent im sending it to the shop next week on Tuesday but trying to save money thats why im on here it has new plugs,wires, and prior to swap I replaced the fuel filter and used my old throttle body that worked perfectly fine on the old motor but i mean definitely doesn’t hurt to have the shop check fuel pressure its obd1 still so i cant plug in a scanner to tell me whats wrong with it
