Dual ECU - new diagrams

I hope this helps you guys out. I know I've been missing for a while but here is the wire-diagram I've created for the dual ECU set up. Let me know if you see any errors.

Remember, there are 3 tabs of excel sheets in that file. The more interesting pages are #2 and #3...

Here it is. right-click and save-as.

This wiring diagram is good for dual ecus (in this case, sporty RS or GS with EVO 8 ECU). If anybody else wants to host it, please feel free - I got the info from here by johnsgalant and just put it in a more understandable format. Print it on legal sized paper and go at it. Page 1 isn't in a friendly printable format - sorry. That was more of a draft page.

Let me explain the first page with the "labels" column - With the wire harness for the eclipse and evo on hand, I simple used those tiny wire markers you can buy at radio-shack to label the wires. As I cut them and paired them accordingly, I checked off one of the 3 check boxes. I then solder them and double check them and check off the rest of the check boxes accordingly. It's just a way to stay organized. Wow, I used "check/checked" a lot in that paragraph.
