This is the Firstech FTI-SPTS-U universal anti-theft integration harness. Sold as a single harness.

Modern relay-attack theft doesn't need your key. It needs your key's signal, and a push-to-start vehicle will start for anyone who can capture it. This harness closes that door.

How it works

While your aftermarket security system is armed, the harness disables the vehicle's push-to-start button. Even with the factory key present, the vehicle will not start until the system is disarmed from your aftermarket remote or through DroneMobile. A thief with a cloned or relayed signal gets nothing.

It has on-board relays built in, which keeps the connection to the vehicle's ignition system straightforward rather than requiring a separate relay pack under the dash.

What you also need

This is a harness, not a security system. It requires a Compustar alarm built on one of these control modules, sold separately:

• Compustar CM-X
• Compustar CM-DC3
• Compustar CM2500
• Compustar CM900-AS

Fitting a 2011 to 2026 Chrysler, Dodge, Jeep or RAM? The FTI-SPTS-CH is the vehicle-specific version for those, and is usually the tidier install.
