One-way remote car starters work just like your factory-installed keyless entry system. A common question we get is “What is the difference between a one-way and a two-way remote car starter?” Let’s explore the differences between and the advantages of both technologies. While we have many repeat clients, there are still many people who are buying their first system. Add further protection by taping them completely.Here at Extreme Audio we are known as the remote car starter experts in Midlothian and Mechanicsville. This keeps them from falling apart and potentially damaging your vehicle. Use a soldering iron to connect all wires.If your starter has two power wires, attach the second power wire on the starter to the additional 12V constant wire. In this case identify which is fused at a higher number of amps and attach your primary power wire to this one. Some vehicles will have more than one 12V constant wire.It should read around 12V (or the battery voltage) constantly. To test the power wires using the multimeter attach it to the wire when the car is off and the key is out of the ignition.If you see any yellow or otherwise noticeable wires, do not touch them! These are the airbag wires and must not be tampered with or unplugged.

You can locate this wire by reading the vehicle’s manual and repair guides or testing with the multimeter. The 12V constant wire is the one attached to the battery and is usually found in the bundle of wires attached to the ignition switch.

Locate the 12V constant wire on the vehicle and attach the power wire of your system to it.
