No you won't throw a CEL if you extend the wires...

That's all I can contribute to this thread though.

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by HondaPartsHero &raquo;</TD></TR><TR><TD CLASS="quote">ECU pin - harness color - connector # - O2 color
A23 - red/blue - 1 - white

</TD></TR></TABLE>

If those wires colors don't work for you, try these:

A23 - wht/red
C18 - grn/blk
12v - color is right...but make sure to put it to a switched 12v source.
A8 - blk/wht
