Hey guys, I just bought a replacement ignition, only so I can sell my ignition with the ECU. I'm running an engine management and there is no need for the immobilizer setup.

My question is about the parts in the immobilizer system, what do I have to sell with my ECU, ignition, and key in order for someone to get a working immobilizer setup? Do I just have to sell the ECU, ignition, and key? Or is there more to it? I'm guessing I'll be ok selling my old ign/ecu/key when I get this other ignition and swap it out, right? By the way, it isn't a new part, I bought it from someone on here. Thanks guys!!!
