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.

On page #2, with the EVO ECU diagram, the bold numbers are FROM the stock harness pin #.
On page #3, with the 3g ECU diagram, the bold numbers are TO the EVO ECU pin #.

Just trying to make it as clear as possible to save people the $300+ it costs to get boomslang to make one.

Does anyone happen to know the part number for the plastic connectors (both male/female for the ECU)? I wish they made ECU harness extenders (male and female ends) for AT RS/GS 3gs. I have one for my EVO8 ECU but that doesn't do me any good (Except the connectors on the ECU side) haha.

check boomslang.us i think they can provide the connectors you need. they can build harnesses so im guessing they can sell just the connectors.

The plan was to buy a female connector for the 3g and male ends for both 3g and EVO so I could make my own outside of the car... but they cost about as much as buying the pre-made custom harnesses!

I'm just going to hack my EVO ECU connectors and 3g stock harness... It finally goes in Saturday.
