Hi everyone,
I'm working on installing an aftermarket ECU in my car and need to connect a 12v input signal to it. However, the ECU can only recognize a grounded switch.
Here's a really poor diagram of how it needs to be wired:
ECU--(wire)--switch--(wire)--ground
The switched 12v is not PWM, and does not carry high amperage. I thought of using a relay, using the 12v signal to close a grounded switch but room is limited and I want to keep things as simple as possible.
Does anyone have an idea of how this could be easily done without the use of a relay? Thank you!!
