I just installed my RRM header, which by the way has really improved performance, my CEL didn't come on until yesterday, i have the fix from ILP performance, but need help on installing it. Can anyone please help me??? (I have the wire in model)

 

Run a search, cuz I think there's a how-to here somewhere. If not, there might be one on ILP's website. From what I gather, you splice it into the wiring for the 2nd o2 sensor.
