well, last time i put one on, i did it there because it was right there.
the other end of the wire works just as well.
what year PCM\harness is it?
if its a [b]1999 - 2002[b] this one applies:

if its a 98, that is NOT correct.

thank you very much, anyone have troubles with an air/fuel guage causing ecm problems? threw one on a 00 a while back and it gave a few problems. i'm thinking about dedicating a o2 for it in the exhaust so i don't have any issues.
