just finished dropping in a obd 1 gsr motor into an eg and everything went fine until the car threw up a 23 engine code which i believe is knock senor. please let me know how and what i need to fix this problem. its the only code that its throwing up. im gonna be taking this to the ca. state ref to get the swap legalized.

you have to extend a wire from the ECU to the knock sensor or to the plugs.... i recomend hooking it up to the plugs because your going to the REF....hybridhonda has the pinouts for the ecu....

what wire do i extend from the ecu to the knock sensor? and would i cut the wire that it has on it now and make a new one?

DOHCtorTHRUST

the knock sensor is right underneith the intake manifold..... there should be a plug(green) with one wire... it should be red with a blue strip on it(im not quite sure about the color)the wire should go all the way to the chassis plugs, but the chassis does not have the wire going to the ECU, thats where you have to hook it up...

http://tech2.hybridgarage.com/ecu.php?ecutype=p72_obd1
plugs A,B,D is from left to right, hold the ecu upward....the pinout is D3(plugs D and the third pin on the ecu...1 is the first left corner 2 is the bottome left corner, 3 is uptop next to 1)one the ecu harness, you will see holes on it, its missing wires....

alright so i follow the wire to the plug in the engine bay? from there what do i need to do? people have told me to look on my ecu plugs at certain spots and said that there should be a wire missing but all the spots that people have been telling me to look at there is a wire already there. i have a 95 si hatch so you know
