Hey guys. Im currently in the process of completely tucking my engine bay harnesses. I just finished up shaving my bay. Its an 01 integra gsr with a P28 ecu. The problem I am having is while in the process of redoing the electrical tape I am also deleting any plugs I no longer need since its no longer my DD(until its completely rebuilt.) The harness was already molested a bit, but the guy did pretty good work before me, but I dont quite know what the deal is with my knock sensor.so far i deleted my iab, evap purge canister connector, power steering pressure switch and ckf connector. By accident i cut the knock sensor connector off and when going to reconnect it, I looked into the wiring color to make sure it was the right plug I was gonna splice in but it has 2 wires. Page (23-18) in my honda repair manual, it calls out C133 knock sensor and it has 2 wires, but when I go to (11-25) it says 1 wire(Red/blue). I also cannot find the engine oil pressure switch plug which is 1 wire(yellow/red) Now my 2-wire connector for the knock sensor has a Red/Blue and a Yellow/red wire. I cannot find anything that helps me during a google search. Theres no way the guy before wired it up this way to have the oil pressure dummy switch to the knock sensor is it? Would thie cause the oil light to flash if there is a knock occuring? I have never heard of this and it would be bad *** if it is in fact the case since im running an after market oil pressure gauge anyways but I have found no one else doing this in a search. Hopefully someone can shed some light on this because this has had me stumped for a couple days now and alls ive been doing is searching each night after work. Id really like to get this harness finished so I can move onto the accessory harnesses. Thank you.

Reason: Typo
Alright so I just wired it up with the red/blue wire and then went to the junk yard and got a oil pressure switch connector and soldered that into place.
On the same harness but different question, since ive owned this car (5+ years) ive always had this plug hanging in my engine bay not connected to anything. It was near the map and tps sensors. I decided to cut it off since its not used but just curious, does anyone know what this originally went to?
Knock sensor
