Been using an Abbott Box Cable X Converter for a few years on my electronic speedo T-5 conversion. Mounts under dash and drives the old mechanical speedo. It is fully adjustable to get speed right! Unit runs about 300 bucks. Can order direct or go through a Speedo Shop. Nevada Speedometer in Sparks, NV is in the know (tech support!) and where I ordered mine from.(775-358-7422). http://www.atrol.com/cablex.htm
