Flex the wire and see if you can get the dash to work. If not you have use a multimeter but you can narrow your search to the wires that power your speedo etc. I would look under the battery tray and under the fuse tray for rubbed through wires. Likely the area where you first found rubbed wires is the problem area.
If you do find a break and you have enough slack in the wire you can cut it at the break strip the ends and use a quality butt end connector, one with heat shrink already on it, and reconnect the wire ends. Then wrap it with electrical tape and see if you can zap strap it out of the way of the air box.
