The stock wire goes from the alternator to the starter with a 10' 8 gauge wire and then from there to the battery through another 8 gauge wire, then from the battery to the top of the under hood fuse box. Our alternator rewire goes from the back of the alternator to the power connector on the under hood fuse box with a shorter larger diameter wire. It can safely be run with the OEM one still connected.

  • More power to the fuel pump 
  • Brighter head lights 
  • Better ignition performance 
  • Better heated seat performance
  • Improve rear defrost performance 
  • Less alternator draw by more efficient power delivery to battery 
  • Better fuel economy 
  • Installs in 5 minutes
  • 4 AWG flexible cable replaces the much longer current choking 8AWG factory wire 
  • New protector boot included to reduce the chance of shorting at the alternator stud.

Works well along with our Alternator Voltage Booster.

This item and all electrical items are non-returnable. 

Connects to top of fuse box and output post on alternator. Factory wires stay in place. 

Monte Carlo/Impala Note: the terminal on the fuse box side must be drilled out to match the larger fuse box stud.

Costly

Nice wrapping but it's just a 4 gauge cable can't notice any difference alone....

Good product

After only having it on for a day, I’ve already noticed that fuel economy has increased, especially during highway speeds, and the rear defrost works way faster. Install was easy, but had to trim the fuse panel cover a little bit.

Poor design

Well I went to install the cable I had to modify the fuse Box by cutting a little bit which was simple but my complaint is the fitment when connecting it to the alternator stud is something that needs a little more thought because that boot is just not working which just cost me the money plus shipping to find out that I just wasted my money

Another innovative part from ZZ Performance!

I like this product. It ensures that there's constant voltage at the fuse box, which allows all your accessories to work better. I know you could probably do this with five bucks worth of wiring from the local auto parts store, but this is custom made for your W body and fits perfectly. Plus it's still cheap so I definitely recommend it!
