I see more EVO 1, 2, 3 in North America lately.
The engine and drivetrain are very similar to DSM/GVR4, so I think there is no problem to find info for repairs, but I see some people are struggling with electrical issues because of a lack of info. It seems there is not many FSM shared on the internet or I'm not sure if they even exist in English.

I have the factory electrical circuit diagrams. But those are paper books and in Japanese. I decided to make it as a PDF file little by little while staying home due to the covid-19 mess, but I would take long to complete since I need to translate from Japanese to English. So if there is someone who really needs some diagram as soon as possible, just let me know. I would take a pic of the specific diagram you need and upload it in this thread to share.

I will post each time when I complete each section/chapter.

It's for EVO 2, but I think almost the same as EVO 3 and I believe the most of part can be used for EVO 1, too.
I tried to pick up only the EVO's infos but some diagrams are shared with 4G9, so just follow the one that says 4G63.
Please excuse any errors/typos in translation, if there is.

Note : I do not take any responsibility for any damage or loss caused through these infos.

I haven't had time to make more Japanese to English translated version, but I have scanned all of them already. So if you don't mind in Japanese and are looking for specific diagram, feel free to ask me.

Besides the diagrams above, I have diagrams below in Japanese. If you need some, please PM me and let me know which one you need. I can send it to you in full size.

By any chance do you have any of the fuse diagrams? im mainly looking for the fuel pump relay...

Download the PDF files in post #2 and post #6 "MPI/Engine Circuit Diagram" and "All Harness/Connector Numbers". Those show the fuel pump circuit and where the fuel pump relay is (In the manual, it's called "Engine control relay" and the connector number is C-01)
And as for the fuse diagram, what exactly you need to know? (Yes I have all fuse diagram but in Japanese)

Ok sweet ill download # 2 & 6. As for the fuse diagrams I was mainly looking for anything fuel related but it would be good to have them anyway. I appreciate the quick reply! I have been having issues with my Evo 2 and recently replaced the fuel pump, car ran great for a whole day then back to the same symptoms as before so now I'm going to start pulling fuses again.
 
Fuel Pump Relay (or MPI Control Relay or Engine Control Relay) is located behind/below the Stereo center console area on it's own, and has a 8 pin connector on it. Pin 7 is ignition power, Pin 5 is ECU pin to control relay on/off, Pin 1 is relay output power supply to the fuel pump which goes to pin 2 of the fuel pump connector. Also check your earthing on pin 1 of the fuel pump connector. That's really all there is to the fuel pump.

Also these cars have notoriously thin wiring for the fuel pumps which struggles to supply good power. If you've upgraded fuel pump I suggest running a separate upgraded power wiring and using an extra relay to control it via original wiring.

@DSMPT thanks for this info. Could you provide me schematics of central door locking and a/c heater unit.
I'm having some trouble with my fan.

Thanks in advance.

Thanks a million bro!

I managed to fix my ventilation problem without but now I can sort out my remote central locking problem.
 
Do you happen to have the meter circuit diagrams?
Here you go. Please check the attached PDF file.
I combined below :
4-41_Meter Circuit
4-42_Fuel/Brake/Oil Pressure/Seat Belt Warning Light Circuit
4-43_Fuel/Brake/Oil Pressure/Seat Belt Warning Light Circuit
