: Constant 12V power supply. Connect directly to the battery or a constant 12V fuse box source.
Because car alarm wiring often differs between specific vehicle models (e.g., a 1999 Nissan vs. a 2004 Toyota), you should always test wires with a multimeter before making permanent connections. If you are experiencing repeated false triggers or starting failures, the internal relays of the Shurlok unit may be worn out.
However, the biggest hurdle for any DIY mechanic or auto-electrician is the wiring. A missing or misinterpreted can turn a simple upgrade into a frustrating afternoon of blown fuses and non-starting engines.
Most modern cars (post-1990) use a .
Unlike plug-and-play OBDII devices, the ER150 requires invasive surgery on a vehicle’s electrical system. If you are dealing with a car that has an existing ER150 installed, you are likely facing one of three scenarios:
Before diving into the wire colors and pinouts, it is essential to understand what the ER150 actually does. The Shurlok ER150 is not just an alarm; it is a sophisticated immobiliser system.
– So users can scale it without losing clarity for workshop use.
