I have a 98 SI or EX and I'm using the original O2 sensor harness to connect to the new one which is a Bosch 4 wire O2 sensor. The colors don't match and this is where I'm having trouble. The original has 1-green, 1-white and 2-black. The Bosch has 2-white, 1-gray and 1-black. I basically need to know what the colors from the stock one are for. I've been trying to find this for some time and can't find it anywhere.
