Installing an s300 in a 2000 Prelude. We will be using a PLX afr sensor module for o2 sensor input, and af gauge. Where have you, would you, put the PLX sensor module? Where, how, did you route the o2 sensor wire bundle to get it into the cabin?

We solved the switched power connection for the module with a fuse tap. If you aren't familiar with this, it is a metal clip that fits over one spade of a fuse. It extends above the fuse so you can solder your power wire to the clip. Then just find a switched power source in the fuse panel. We are going to use the radio fuse relay.
