Default o2 bank 1 and bank 2 #1 pcm wire ?????

for hooking up o2 guages to each side, should I run a wire down to the o2's or is there a particular wire on the pcm that would be much easier to "tap" into?, wich ones for both the front censors?, cant remember off the top of my head but there's 2 sets of 32 wires right, 1st on top and 2nd on bottom?

yeah, hooking up air fuel guages, I wuz hoping to splice into the pcm wire instead of running wire down to each side of the motor, make things a little easier and cleaner!

Here's the best PCM pin assignments list I've found.

On my 02 LS1, I ran a tap on numbers 66 and 69 to get B1S1 and B2S2. Seems to work wonderfully.
