With the '87 through '89 Mustangs being at least 25 years old, many of them are actually going through restorations. Harnesses and wiring are one of the main problems with these cars because over the years they get cut up, they get changed, and cause a lot of problems for restorers who are trying to put the cars back on the road. This complete chassis harness will give you everything you need for the chassis of any '87 through '89 Mustang.
The basis of the kit is going to be their new under-dash wiring harness. This will work on any '87 through '89 whether it's a 4 cylinder or GT. It will work on all body styles. It will work on a convertible but it does not include the wiring for the convertible top switch. Includes a new fuse block, new switches, and all factory-style plugs, making it a plug and play installation.
For additional protection along with the fuses and the factory fuse block, American Autowire includes this 175-amp mega bus fuse to mount to your main power source before powers goes to the rest of the harness. This is going to be your rear body harness. This is going to give you brand new wiring for everything in the back end of the car, including your taillights, backup lights, along with the fuel pump, third brake light, and the defroster.
The kit includes brand new factory-style sockets that will use the original light bulbs. This is going to be your dash and gauge harness here. This has everything necessary to hook up all your factory gauges to the factory setting units, and it actually has additional circuits built in for adding aftermarket gauges such as a boost gauge.
The last harness here is going to be your headlight harness. It runs the headlights but also runs every accessory in the front of the car, and has additional fusing and wiring built in to run an electric fan. Again, it uses factory-style sockets that will use original-style bulbs.
American Autowire knows that wiring can be very intimidating, so with their kit they include a large selection of full color diagrams showing you where all the connections are made, where all the wires get run to.
If you're looking to restore or you're just working on your '87 through '89 Mustang or having wiring problems, this American Autowire harness is a great idea to correct those issues. Keep in mind, this is just a chassis harness, does not include engine wiring such as the injector harness or the main ACU harness.
