You Are essentially continuing the flow of an electrical circuit when your connecting a wiring harness for your stereo. Make sure to use the proper tools such as solder for your connection or “crimp caps”. Crimp caps are pretty easy to find at your local parts shop, even at your local car audio shop. Soldering is a bit more difficult, your using a soldering iron that gets extremely hot to melt led free solder onto your wiring connection. I promise this is easier than it sounds.

How Do I Find The Right Wiring Harness?

Believe me, there is no art to it and you don’t need a degree to find the correct harness for your vehicle. However, there are a few pieces of information you need to know in order to find out. You know them very well…. well… you should. They all have to do with your vehicle and the options it may or may not have.

  1. What is the year of your vehicle?
  2. What is the make of your vehicle?
  3. What is the model of your vehicle?
  4. Do you currently have a factory amplified system?
  5. Do you have an aftermarket radio already?

If you answered yes to number 5 then you wont need a radio harness more than likely. Generally shops use a wiring harness to install aftermarket radios assuming there is a harness on the market for that vehicle.

If you answered yes to number 4 then youll need a special harness that provides a low level signal to your factory amplifier. You may not know you have an amplifier, or a factory subwoofer. Dealerships don’t generally explain your sound system specifications, they’d rather just take your money.
