      Review & Installation Video

      Hey, guys, Stephanie with, here with the review and install of the PA Performance Premium Power Wire Kit for 1994 to 2014 Mustangs. You're gonna wanna check out this power wire kit if you have a high amp alternator and you wanna upgrade your power wire to carry the larger load that the alternator will produce. The stock OEM Power Wire from the alternator to the car wasn't designed to carry the larger loads, so when you spend your money upgrading your alternator to a high amp one, you wanna make sure that you're getting the full benefit so you need to upgrade your power wire. And I know that '05 to 14's can have that annoying check charging system notification since there is an issue with factory alternator and power wire so an alternator upgrade and this power wire kit will eliminate that issue for you and stop you from going through batteries. This kit will work with a factory alternator but it's really designed to carry the larger load of an upgraded component. The only thing this kit will not work with is the GT500 models. If you have a GT500, there's a specific kit that will work for you. This wire is a 48-inch, 4-gauge wire that has more strands than the factory wire, which is how it carries the larger load and it also has bundle wrapping, which is gonna reduce noise in high-end sound systems. The wire is finished off with new looming so it'll look nice under the hood. When it comes to price, you're looking at spending right about $50 for this power wire. It's gonna be your only option on this site when it comes to power wire upgrades but this will work with any alternator, stock or aftermarket. The install for this is not difficult. I'm gonna call it a one out of three wrenches in the difficulty meter, which take an hour or two to install and you need a few tools to get the job done. The wire itself is only two bolts and this is a part that fits a wide range of years. So depending on what year of Mustang you have, the specific steps and routing maybe a little bit different but generally speaking, the overall install will be the same. Either way, you need to disconnect your battery. The power wire bolts into the back of the alternator and you can remove that and the other end at the battery as well. You're just looking at unbolting two bolts here. Pull your new power wire up in the correct orientation and route it away from any danger zones. After that, you can connect your battery and that's all it's gonna take. Wrapping things up here with the PA Performance Premium Power Wire Kit, this kit will fit all 1994-2014 Mustangs, except the GT500. You can check it out more online right here at

        The eyelet holes are the perfect size to connect to the alternator and to the power supply. I ran mine straight to the battery. I upgraded my wire because I went with a 200 amp. alternator. Keeps the battery voltage at a constant 14.4 volts.

        Great product!

        Essential if you upgrade your alternator. I moved the wire off of the injector rail and attached it to the stock engine harness.

        Good product... but not as easy as it seems...

        Note, this review is for those of us who don't regularly work on our cars, but are capable enough to do so... (I submitted a Before/After photo and review as well...) Good cable quality, and I think it's a necessary addition if you are upgrading to a higher power output alternator (200amp)... but the stock advertisement photo is a little misleading. It does not include enough conduit to cover the whole cable, and you will probably need to unwrap the old cable in order to re-use some of the old conduit (if you didn't plan on buying extra), as well as to re-use the cable mounts that hold it in place.

      I replaced my alternator in my 98 mustang gt with just another 130 watt alternator. I replaced the battery as well. My alternator is not giving enough power to the battery if any at all. I got the alternator tested and and it as well as the regulator is fine. Would this wiring help with the problem? If unknown would it work fine with a 130 watt alternator?

      • The PA Performance Premium Power Wire Kit may help with the issue you are experiencing, however we would recommend having the car checked by a mechanic to determine what is causing the issue.

      I got the kit, and I'm really confuse how to install, I have a GT 1995, should I replace the OEM wire to the new kit? Thanks! SC

      • You will need to remove the intake manifold, in order to get to the back of the alternator and change the stock wire for the PA Performance Premium Power Wire Kit. If you are having issues with the install we do have an install guide for you here: . In addition to this if you were having any further issues or had any further questions please feel free to give us a call directly here at 1-877-887-1105 as we would be glad to help assist you!

      Does it matter which side the fuse box is installed? We had a mechanic do an install of the new alternator and wire and he installed the fuse box near the alternator instead of near the battery like I would expect. Also, where should the wire be routed? He ran it along the valve cover, wasn't sure if there were heat issues with that or if that is normal? I don't recall where the OEM run was to be honest.

      • Typically you would want the fuse installed as close to the battery as possible as this maximizes the amount of wire that is protected. Routing can be done a number of ways, but this should be isolated from moving parts, metal parts, and heat to prevent issues. We strongly recommend the routing be corrected and the fuse be moved closer to the battery as soon as possible to prevent any chance of a fire.
