What can this sensor be? PLZ HELP!!

[jdmda9]

Ok so im swapping a 93 b17a1 GSR swap onto my 90 DA integra. As you may know, the b17a1 swap is obd-1 and the 90 DA that im dropping the swap into comes in obd-0. So of course the engine harness is going to have different plugs.

So heres where im stuck. I planned to basically use the obd-0 engine harness off of the LS and convert the obd-1 b17a1 swap into a obd-0 motor. I intended that so that my swap could run fine and not have any check engine lights. I knew that i would have to change up/exempt something so that i could make this work. So heres where i ask from you guyz help!!

So i have come across one sensor on the back of the b17a1 block that my obd-0 harness doesnt have the clip to. I lost the obd-1 harness so i dont have a refference to use. And heres that plug:



I heard that this is a knock sensor but then again i heard that only 0bd-2 and up vtec motorz have knock sensors. Not obd-1 and down. So whats the real deal here? I heard that this sensor can be straight wired to the ECU (that is if infact this is a knock sensor) or what can i do?

Im a perfectionist when it comes to cars so im not moving any further with the swap til i get this fixed! PLZ help ppl, cuz i hate having a check engine light so plz help a brotha out!!! REPZ WILL B GIVEN!!! THANX!!!

If youre keeping the car obd0 then you dont need to worry about it at all. Just take it out and sell it.

well i found out how to wire this knock sensor after all. it goes in b19. yea maybe it doesnt need it since its obd0 but i feel better if i know that i have it wired! and im also planning to run a 0bd1 p61 ecu so i think its going to ask for the ks. either way i got it so thanx to everyone!!! reps!!!
