Step 1: Disconnect the negative cable from the battery.
Step 2: Disconnect the other end of the negative cable from the stud on the engine block.
Step 3: Using a box cutter, carefully cut the tape that holds the corrugated loom and cables together.
Step 4: Locate the “Y” in the negative cable and cut the wire going to the alternator as close as possible to the “Y”. Crimp a heavy-duty #8 gauge 5/16 lug (#10 gauge is too small) on to the end of the wire coming from the alternator (the one you just cut – a 310 gauge crimper works OK). Apply heat sink to seal the connection.
Step 5: Plae the ring end of the new battery cable on the engine ground stud, then install the alternator ground wire (with the new end) and replace the nut.
Here is a sketch of what it all looked like when done.
The chassis ground on our cables is a few inches longer than stock for ease of installation.
The cable is a little long at 30 inches but that is what the factory cable was.
