to hide them, you have to reroute them between the outside of the fender wells and inside the fenders. if your referring to the wiring for the stock carb (only if you have a weber or aftermarket carb) you can get rid of all the wires coming out of the big groment on the passenger side fender. except the wires for the wiper motor, 4 blues and one black.
as you can see in the photo ive unwrapped all the wires. seperated the blues and one black for the wiper motor. i then unplugged everything that was connected to the harness minus the wiper motor and removed all those components. you can then push the entire harness through the hole and unplug from the ecm (which is also useless with a weber or aftermarket carb) and either cut the wires that go behind the dash or removed the blower assembly and unplug the rest of the harness for a cleaner uninstall.
