Electronic Speedo Hook up
If you cannot do anything else, go down to RadioSH## and buy a stereo headset extension cable. That will give you a 2 conductor shielded cable like below
Lowes/ Home Depot, does show "shielded security cable" on their site. In this locale, Lowes does sell "by the foot."

Ground one end, I would first try right at the sender, and insulate the shield at the speedo end.
