ok i have removed the igition switch and the instrument cluster to trace the power problem with my turn signals. In doing so i found a burnt wire that goes to the igition coil and voltage reg and the brake light. That is a problem. The wire as indicated by the (jim orborn elec. book ) is 904,16a if i am reading it right. The question is that i have a extra wire on my igition switch which is red w/white strip and that is not listed. Does anybody know what that wire does or is. I need to remove the wire pin connector if it is not needed to repair the other burnt one. Keep in mind that my amp meter does not work and i have a miss, could this be a possible cause.

The actuall switch is fine it is the clip that is damaged. The red and green(16) is burnt up into the clip that is why i was wondering about the extra wire. This was burnt up before i got the car so i do not know why it happened to beging with and the car still ran with it like that. I have been decifering or tiring the wiring and am finding all kinds of connections that have been tapped over with just wire twisted together. I started this to find my turn signal problem witch i have not found as of yet. Tring to get all this other stuff taking care off to see it that is the problem. Can you just get the clips somewhere incase i destroy this one?

Best thing to do is to pull the harness completely out, and using the Jim Osborn schematic, rebuild it (fix all the sins). If there are additional wires, determine what they are and decide what you're going to do about them. I used an old harness scrounged off a Falcon to use for repair wire. Having the same color coding as original makes the end result like having a new harness.

Good advice and make sure the pink resistance wire is not cooked also. I ended up buying another harnesss and keep the repaired one for whatever. 68's are known for ignition problem. Try to get a Ford switch. Check all your grounds and clean up the contacts in your fuse panel too. Also, you might check the headlight harness in engine cmpt. The green wire was cooked in mine from end to end. The Osborn 68 electrical is a must.
