Thank God for DooTalk, as per my previous post which went to three pages, I finally got my speedo working again. Per the insistance of a couple of you, and an extra thanks to new2memxz670 for listing the part number, I changed the relay by the airbox and speedo now works fine. The thing is, this is one of the first things I tried, with a relay that I got from autozone. The autozone guy just matched up the pins as I didn't have a part number. When I plugged in that relay, the problem still existed. Tried swapping everything from my wifes sled, speedo and tach, speedo pickup, tried all wire unplugging that I could, all to no avail. Using Napa/ECHLIN AR143 relay and problem solved, don't know if the autozone relay is defective or a different layout, the plugs fit fine, so somthing to watch for. But once again guys, thanks very much,,,glma
