installing new battery cables on '66 barracuda

having had a 66 and now a 65 restored both you should have no extra wires going to battery cables beside ground wire. It would seem the previous owner has rigged many other wires to the battery direct, it is not unusual when one cannot figure where to run wires on older cars. However it can cause other problems is not done properly and grounded properly as it seems to be the case. I had this on my 66 when I got it and restored it for driving and drag racing as a street class car, I installed a seperate wiring system for extra things like radio and electric improvement to motor as it had a 318 w/ electronic improved mopar power system.
