o2 wire at ecu
what color is the o2 sensor wire at the ecu. I know its the black wire at the o2 senser but is it black at the ecu and is it the only wire that color.

But that tidbit is negligible, because I used that info, wired up MY A/F gauge (which I'm ASSuming you want to do, based on what you're looking for), and found out through trial-and-error, that this wire was the throttle position sensor wire. Still looks cool, as it activates the gauge and all - and you can even probably use this to gauge just HOW the gauge will look when it's correctly hooked up - but it does JACK for actual application of the gauge in determining any kind of lean/rich status.

Ummm, it's very easy to understand if you're looking for a particular wire. if you can't find it on a well laid-out wiring diagram, what makes you think you can find it on a wiring harness that's smashed together and twisted into knots?

it's not that hard. but if you can't find it, then you probably shouldn't be trying to do it yourself. I wouldn't expect a rookie to be able to do engine work, so why do you think hacking into a VERY critical part of your electronics is a walk in the park? If you screw it up, you can do some pretty major damage that can cost hundreds to fix.
if you can find it on your own, then I have more confidence in you being able to properly install it--and better yet-- fix what you break on the way in there.
