You dont need that wire, just have Allen disable the codes for the L and F terminal circuits and you'll be fine!

I was allwas told that the 02 ECMs where bigger, and was less likelly for faults KR. I now have heard the 99 ECM's are faster, but the O.S is not as good as the 02's?
I have a 02 (from Allen) and believe it is the better of the two.

05 CBR 1000rr
the 02 has the faster processor and less likely to have false knock. The 99 pcms suck the big one IMO. You can either get an 01-02, they are both the same.
