A/F gauge hookup..

[Swifty1638]

I searched, but no results..atleast, not what I was looking for. I was looking through vfaq, and saw there was a different way to hook up a A/F gauge, then tapping off of the o2 wire. But, the link for that is not found. Anyone know how to do this, and if i must tap off of the 02, then how can I? Which wire is it?

P.S.- I know it's not accurate. It's not my method of tuning, but when the chicks dig the light show, i tend to give them a fricken light show!

There should be a wire behind the passenger side kick panel you can splice into. i can get a pic of mine if you need it.

I can't think of a single girl who I'd actually considering dating who would actually be impressed by a blinking LED light. To each their own. Hook it up to the power, ground, and o2 sensor wires on your ECU harnesses.

Well, it's not dating..it's more a conversation piece..lol. I do need a pic. The link that the site had doesn't work. I wanna know how to do this correctly, the first time. Email it to me Anthony.Swift@comcast.net thanks!

Or just got on vfaq.com and print out the directions and do it. Its pretty simple with the wiring diagram.

So, it's that single wire, furtherst to the left?

Craig, I looked, but apparently the link no longer exists. Do you have it? I'd greatly appreciate it.

There are multiple ECU wiring diagrams all over the VFAQ, you can even get it from Apexi's website. The Apexi TT monitors o2 sensor voltage, use that wire for your worthless gauge that'll drive you nuts after 1 night (ask Cory, aka talontsi85).

There is the 1G ECU pinout above.

The #4 pin on the far right plug is the Oxygen Sensor wire. Tap into that and then you just have to find a power and ground. You can use either pins 101 or 106 for a ground. Power I will leave up to you because there are numerous places you can get power from. I can't remember the best one or the one I used but I am sure somone will.

Hope this helps.
