Wanting to swap both the Positive and Negative cables, and I was wondering if they are specific to ZR1, or if they are the same as any C4? Anyone know the part numbers?

Also, is the alternator pigtail the same as any other Corvette?

Thanks!

I believe the positive is ZR-1 specific. The negative could be any type. You could fabricate one but here?s a pic of what the reproduction looks like. 90-92 pictured that I?m aware of. If I recall when I replaced mine, the small red wire with a plug powers the ECM. The slightly larger and longer wire goes to the hot at all times junction under the primary and secondary driver boxes, large gauge cable bolts to the starter solenoid. The braided line is a ground strap that just happens to be bundled in with the positive battery cable assembly.

Awesome!
Thanks very much.

The wires changed over the run, I do have a NOS I think a positive for 93-95 but Id have to look. Do you need one?
