ok so i'm finishing up this guys swap he did on the car i bought from him. its a 91 LS integra with a JDM B20 in it. i have a couple questions about the wiring. Well on the back of the block on the stock integra B18 there are 3 sensors that go there but when i looked in the back of this B20 because i saw wires hanging, there is only one sensor and i think its for the knock sensor right? well anyways, these 3 sensors are missing from the B20 block so what should i do ? anyone have this problem OR is it just with the JDM B20 that there will be sensors missing? i have 4 wires(for 3 sensors) that SHOULD go to the back on the motor like it does on the stock B18 but when i searched for them on the B20 there is nothing? ANY HELP PPLEAASEEEE! i think the sensors or for the fan? any 2 other things? thanks!
