Subaru SSM to Can-Bus Convertor DIY

[Ajzride]

I had to borrow some alligator clips from my breadboard setup to work in the garage, and when I went to clip things back together, I got the 12V meant for the ECU clipped into the 5V meant for the UNO, so I smoked the UNO. Second time in the last few weeks I've sent 12V through a 5V channel. So I'm down for a few days while I wait on another Uno (I ordered 4 this time). I took some of my time to draw up how I have things wired up on the breadboard.

The OBD-II port shown on my drawing is for CAN-BUS, it is not the OBD-II that the ECU hooks into, that will T off of the purple line on C16 of the ECU.

Chassis and 12+ IGN are being provided by a 12V power supply while on the bench.
