Electronic Speedo Hook up

Lets get back on topic. I hear about shielding the speedo wire, what shielding is preferable?
Wrangler Power Products is where I got the stuff I used. It is not in the catalog anymore so you would have to call them. If there is a Frys Electronic Store near you they would have it, I think. It was basically a braided stainless sleeve that went over the wires. Wish I could be of more help......
