Best location to tap ground and power

Hey,

I am just curious what you guys suggest as the best place to tap into for ground and constant 12v in the vicinity of drivers side (LHD) around steering column or kick panel area.

I was expecting to see a common ground piont behind the kick panel but there was nothing. Also had hope to see a power source in that area akso. I wanted to see if anyonr could suggest a better spot or should I just splice into existing wires. Dont wanna run all the way back to the battery.

It's for an immobilizer unit. I am thinking possibly ECU or diagnostic port but I do not want to fry anything.

Thanks,

Cig lighter socket is always powered. Find any metal for a ground. Be sure to fuse it at the source.
