How many circuits are on a 1968 LIncoln Continental wiring harness? I have installed air ride, an auxiliary fan for the radiator and a stereo so i'm thinking that i need a harness with more circuits.
I wouldn't mess with the harness, just run your own wiring back to the fuse block and add a circuit there, most fuse blocks have open spots to add a new fuse (you can even add an additional block off an existing one), just watch how much current you plan to draw, for hi-amp circuits run it back to the battery cable and use an in-line fuse.
