RFID Ignition

Description: Connect relays in parallel with the key ignition. The wiring schematic includes connecting one wire from the 87 terminal (orange) to the red wire, and then connecting the blue wire from the next relay to the black wire, and so on. There is uncertainty regarding the ignition portion. A link to another forum is provided for further discussion.

The circuit involves integrating relays into an existing ignition system to enhance functionality, such as controlling additional devices or systems that require activation upon turning the ignition key. The relays act as switches that can handle higher current loads than the ignition circuit itself.

To implement this circuit, the following connections should be made:

1. **Relay Configuration**: Each relay typically has several terminals, including the common (C), normally open (NO), and normally closed (NC) terminals. In this case, the focus is on the NO terminal, which is activated when the relay coil is energized.

2. **Ignition Connection**: The ignition switch will provide power when turned on. This power should be routed to energize the relay coils. It is essential to connect the ignition wire to the relay coil terminals. This allows the relays to close and complete the circuit for the devices they control.

3. **Wiring Details**:
- Connect one wire from the 87 terminal (orange) of the first relay to the red wire that powers the device or system intended to be activated.
- From the second relay, connect the blue wire to the black wire, which may serve as a ground or another power source, depending on the specific application.
- Ensure that all connections are secure and insulated to prevent short circuits.

4. **Power Ratings**: It is crucial to select relays that can handle the current and voltage specifications of the devices being controlled. The relay should be rated appropriately for the load it will switch to ensure reliable operation.

5. **Testing**: After wiring, the circuit should be tested to verify that the relays activate correctly when the ignition is turned on. It is advisable to use a multimeter to check for continuity and proper voltage levels at various points in the circuit.

6. **Safety Precautions**: When working with automotive electrical systems, it is important to disconnect the battery before making any modifications to prevent accidental short circuits or shocks. Proper fusing should also be considered to protect the circuit from overloads.

This schematic approach allows for flexibility in adding or controlling multiple devices from a single ignition source, enhancing the overall functionality of the vehicle's electrical system.You wire in some relays and run it in parallel with your key ignition. The wiring schematic is as follows: So do I connect one wire from the 87 terminal (orange) to the red wire, then the blue wire from the next relay to the black wire and so forth I understand everything else. I`m must not sure about the ignition portion. The following is a link to another forum that shows some discussion. I`m asking here, because I wanted the opinion of a fellow Winger.
