'67 thru '72 Chevelles have a #14 fusible link in the wire connecting the battery + terminal to the junction block on the back of the rad support behind the battery. '64 does not show a junction block. '65 & '66 have a junction block but the circuit diagram doesn't show a fusible link.

There's one also off the voltage reg. If you peel the tape back far enough, right befoe it goes into the main harness. This is on a 69. Not sure if 66 had it. Rick..

I was taught to never exceed 6" when using fusible link. I don't know what would happen if you were to exceed that length.

The general rule of thumb you can follow is to use 4 wire-gauge sizes smaller than the wire you are using it on (i.e. 14ga wire uses an 18ga fusible link). You can buy these at your local auto-parts store. I have found on some vehicles that the fusible link was changed to an actual in-line fuse that is wrapped in the harness, from the factory.

I've used fuse wire in place of the links in my starter harness (they were almost totally deteoriated), but I used the same size fuse wire as the size wire I replaced. This at the recommendation of a very experienced mechanic.

EH is correct, fusible links in GM cars are always 4 gauge numbers smaller than the wire their protecting.

Wire Link
10Ga 14Ga
12Ga 16Ga
14Ga 18Ga
16Ga 20Ga
Etc.

Fusible links are really just standard copper wire with low flamibility insulation (silicon over XLPE). However, their not totally flame proof and can start fires. If I'm not mistaken, excessive length increases the fire hazard. Modern designs have eliminated fusible links in favor of Maxi-fuses.
