if i have a 95 ex 5 speed wire harness then it should plug and play w/ a jdm b16a2 from a 92 and up civic? just doing some research, so once that bad boy is in my car, i'm not left w/ my pants at my ankles. latez

 

JDM cannot be used, on USDM or any LHD car, because all the plugs are reversed... but not to worry since your car is a EX, and it came with VTEC and all the necessary sensors minus the knock which is very simply wired to the ecu D3 location...basically reuse your old harness and be done with it...

 

so basically just plug and play the ex harness to that engine and screw the knock sensor? if thats the case cool muchas gracias. but if i want to wire the knock sensor to the ecu i would just have to hard wire from the knock to the ecu pin d3? hollar back and i appretiate the info.
