#33350, "RE: speed wire in our ecu?" In response to Reply # 0
Don't know if you're talking about tach wire or speedo wire. I've never hooked up a TT. But the pinout for S-AFC connections is 1/2 way down this page (http://139.55.18.193/Verizon%20A/safcinstall.html). It has the tach wire callout, but not a speedo. Don't know if it will help or not, but it's all I can access right now....
