wiring diagram

whats the quickest way to get a wiring diagram for a 68 dart.......do i need to spend big on a service manual and then wait weeks for it to get here or is there somewhere faster online??

im going crazy with Previous owner mods on my 68 dodge dart ........self proclaimed electical engineers need to be banned from touching old cars.....

aftermarket horn switch ......butt splices everywhere.......extra wires everywhere.....and my favorite .....added lights under the dash cluster bezel that came on with the turn signals...WTH

their brilliantly engineered mods also made the front turn signals come on when you press the brake pedal LOL
