Here is what I have as far as the wiring goes. Note: this info was taken from my 94 Factory Service Manual. I can say for sure that the 95 is different from my 94 because I cut the dash plugs out of both and compared them. This may have to do with the OBD II stuff, I'm not sure. If your wagon is newer some of your plugs will be different.

There are 6 plugs that connect the engine harness to the dash harness on mine. My wagon was also an automatic though with most all of the options, not sure if that matters or not. The plugs are D-06, D-07, C-15, C-16, C-17, C-73

First I will list the connector, then the pin #, then the wire color(s), the purpose of this wire and lastly the section of the Factory Service Manual where this info was found.

D-06
pin 1= empty
pin 2= empty
pin 3= red/green, O/D off (8-84)
pin 4= light blue/orange, auto temp (8-87)
pin 5= yellow/red, low gear ind. light (8-84)
pin 6= yellow/black, D2 ind. (8-84)
pin 7= yellow, D ind. light (8-84)
pin 8= black/white, N ind. light (8-84)
pin 9= red/light blue, R ind. light (8-84)
pin 10= black/yellow, P ind. light (8-84)

D-07
pin 1= light green/red, check engine light (8-74)
pin 2= empty
pin 3= empty
pin 4= yellow/white, reed switch (8-76)
pin 5= white, tach (8-197)
pin 6= yellow/red, engine coolant temp gauge (8-198)
pin 7= yellow/green, brake fluid level sensor (8-199)
pin 8= empty

C-15
pin 1= light blue/red, wiper (8-238)
pin 2= light blue/black, wiper (8-238)
pin 3= light blue/white, wiper (8-238)
pin 4= light blue, wiper (8-238)

C-16
pin 1= red/green ????????????????
pin 2= black/yellow, battery back-up (8-74)
pin 3= black/light blue, fuel pump (8-73)
pin 4= yellow, data link connector (8-76)
pin 5= empty
pin 6= empty
pin 7= black/white, ignition coil (8-174)
pin 8= green/white, data link connector (8-76)

C-17
pin 1= yellow/red, cruise control, (8-122)
pin 2= black, ground for cruise control (8-122)
pin 3= green/white, cruise control (8-122)
pin 4= red/white, cruise control (8-85)
pin 5= light blue/black, cruise control (8-121)
pin 6= green/yellow, cruise control (8-121)
pin 7= black/yellow, O/D switch (8-85)
pin 8= green/white, illumination for O/D switch (8-85)
pin 9= pink, data link connector for auto trans (8-88)
pin 10= light blue, ignition/OD switch (8-85)
pin 11= empty
pin 12= red/light blue, cruise control (8-85)
pin 13= light blue/white, cruise control (8-121)
pin 14= light blue/orange, cruise control (8-121)

C-73
pin 1= empty
pin 2= empty
pin 3= empty
pin 4= black, ground (8-76)
pin 5= black/red, O2 sensor (8-75)
pin 6= black, O2 sensor (8-75)
pin 7= white, ???????????? assume O2 sensor but haven't verified
pin 8= black/white, ?????? assume O2 sensor but haven't verified

If you happen to find some of the wires that are missing please let me know and I'll update this. Also I will be working on posting up the DSM plugs and their corresponding matches.

I have spreadsheet comparing my '93 ECU pinout to the 95 DSM ECU pinout. But I didn't even take out the dash so I didn't play with dash wires.

Oh OK, this is for people that want to just swap in an entire 1g/2g DSM engine harness and connect it to the stock dash harness. To me this seems like the easiest route.

This is good info thanks

I used my stock harness (93 Summit), which has 3 plugs that plug right into the 2G ECU, I repinned it to resemble a 2G harness under the hood and added a 4th plug. I reused original wires going through the firewall, so I didn't have to add a single new wire!

As far as dash wires are concerned, it is all original, except for couple re-pinned wires and tach might have a new lead. My spreadsheet shows it all.

If you are going to use my spreadsheed, I am not sure what is earlier, but staring out from scratch I would do a comets harness swap.

BTW, one of my last moment problems was the MPI relay curcuit! My original wirering reused van's MPI logic, which worked "OK", but... It would loose all V3 DSM Link setting EVERY time it was started! As we know, that shouldn't happen...

I had to rewire the MPI to resemble DSM logic (which is different from the van's).

So make sure you understand this before you take on "my method"!

Leon, would you mind sharing your work to help others out in the future? I have no idea what I'm going to do on my wagon. Either use a J&S safeguard and the stock ecu (chipped for 450's), a patch harness for the 2g ecu and some kind of DIS swap keeping it SOHC or a DOHC swap and a 1g dsm harness like Micah did.

Just looking to slap on a 14b and some 450's. Seems a lot of 7th gen Galant guys have done this on their SOHC 4g64's with no issues.

I think a Evo 3 ecu would be a easier swap? The Evo 3 ecu has 3 plugs like the factory ecu and if I recall there are a few pins that need to be added and a few to swap. Also the Evo 3 ecu is eprom already (mine is MD322364, with a E1 in the bottom corner) that can be used with a link setup. The only other thing that has to be done to make link work is a jumper has to be switched inside, which you can have done when link is installed.

I actually have a Evo 3 ecu sitting here, MKO from galant tuners sent me the wiring pinout diagram to use (the 7g 2.4 sohc galant ECU is very similar to ours, the pinouts are in the same place, a few wires are different colors though). He's the one that actually got me interested in the idea of using the Evo 3 ecu, since its such a easy swap (hard to find a good unmodified evo 3 ecu though, got mine from Malaysia). I also think the EVO 3 has more aggressive timing maps and was setup for 510cc injectors and a big 16g if I remember correctly. Any how it will probably be summer before I feel like messing around with a ECU swap.

Oh and a little off topic: That TD06H 20g that I thought I had, turned out to be an old school FP Green. I was chasing my tail trying to figure why it wasn't spooling similar to other 2.4/2.3 stroker setups running TD06H-20g's, figured out why. A 20g compressor wheel is dwarfed in comparison to the garret T04E50 trim compressor wheel

If you guys have images of these pinouts, feel free to post them up. Even better if they show the changes made to the pinouts/colors. I can add this to the archives for future use as people perform this swap.

Thank you for posting this up.
I have a pig tail from a '92 Mitsubishi expo that has a c-17 pin 6 that is light blue/yellow on the male pinned side and it is light blue/black on pin 6 on the female side of c-17.
would it still serve the same function as that of the green/yellow cruise control?
I will post up pictures as was requested.
again thank you for this post.

The 92's were completely different so I doubt it. Your best bet would be to order a cheap factory wiring manual. I got mine on ebay for next to nothing.
