    I am in need of help as my truck has no electrical power. I have found the 90 amp fuse which sits near the fuse panel on the firewall has a red and gray (maybe a blue color) cable. I have no electrical power to these cables which lead into the instruments. I need to know the wiring diagram telling me where these two wires are attached so that 12 volts can get to this 90 amp fuse. I would be most grateful for anyone willing to help

    The main power feed for that megafuse comes from the positive post on the starter. The blue wire is probably a fuseable link.
