I recently bought a Greddy turbo timer for my 2000 honda civic. I have all of the wires ran and hooked up eccept the speed wire that runs to the ECU. I found a write up how to hook everything up, but its was for a obd1 civic and I have a obd 2 civic so the wires to the ECU do not match up. Some one please tell me where to connect my purple speed wire on my obd2 ecu, thanks.

 

hey man i got a black greddy turbo timer as well that i have to hook up but am really lazy, were did you find that obd1 civic wiring diagram? im very interested

 

I actually didn't find an obd1 wiring harness, I just found this DIY of a Greddy turbo timer on TurboD16.com under the DIY - Do It Yourself and How-To Guides! on the front page. Then click on the link that says Greddy turbo timer install. This is a great web site and has helped me with tons of stuff.
