    mx3 gtr build

    I was going to sell my mx for 3 grand today and the Guy was just not the one and I realized I can't get rid of it especially to someone who wasn't going to appreciate it . So I decided to rip the wiring back out of it cause something was wrong and then decided to get all right harnessing and just tear it apart and have it back on the streets for summer. And make a gtr motor build section for people who had trouble like I did when I first did this so ill edit pics and specs and let you know as I go

      Sorry bout the time and no pic we got 3 feet of snow and are now just recovering and i did get to the garage and got alot of work done.Tried uploading pictures but not working right now. I will get them on by the end of tonight but i took wiring out and looked over all wiring and found under the fuse box that it had a lot of problems. So i decided im going to go over all wiring in car and make sure everything is proper. In the mean time i need help because im going to redo wiring under the hood with everything and go back to stock ECU to make sure everything is good because with the problem i was having my car is stalling and not even starting right now so harness and fuse box harness i think im going to replace where am i going to find this for the motor?

          Should I find a fuse box harness out of 94 mx3 or should I get it out of something else ? If so what?

            Was this a V6 MX3?

            I am not as familiar with MX3s, but since you have a BP in there, I would stick to wiring from a BP powered car (Protege, EGT). The MX3 RS might have the same wiring as the SOHC 323, Protege are very similar to the DOHC (they are missing some bits and pieces in the engine wiring such as VICS but nothing major).

            I would definitely have the Protege/323 FSM handy for the wiring section.

              It was the dohc before I swapped the BP in but I was the one who bought the gtx and got the gtr and now my wiring is vfriend especially under they fuse box so I need new harnesses but can find anything around me

                If your mx was a 4cyl, just install back your fuse box. The wiring are the same since both BP and B6 alternator/starter sits behind the engine. If your mx was 94up, you had VSS and the wiring for that is in your harness. Unless you buy a progt95-up VSS to recover your odo, or if you plan on using wire style or if you got a 92-93 SOHC engine, you'll be ok with that, the odo speed gear are the same.

                If you need anything else to know about mx3, I can answer any questions, just keep writing in your post,

                  Alright my fuse box harness is done for definitely need to replace it but I am having no luck with mx3 harnesses around me. So if I'm looking online for it what fusebox harness am I specifically looking for to work properly with motor because you have a good point with VSS
                  . Never worked so something I can fix while I'm doing this

                      And also power steering is another thought. Should I just get rid of it none of my cars have power steering. Everytime I go to do it I don't but it will free more space and make it a lot better

                          YOu should just get a EGT or Protege Engine harness and just run that. The gtr ecu plugs right into the harness. All you would have to do is get some high impediance 460cc injectors or wire in the resister box for the gtr injectors.

                              Well yun the reason mine is bad now is cause I bought one that was hacked but it wasn't off here so if you say its in all good working condition and will work in my 94mx ill definitely buy... and bom I have so many harnesses I'm going to post pics of later with the ecu I found because I forget what's what.. for the injectors I have high imp. And resistor if ever needed. .and for nerd I got it off Of Howe racing very nicely finished with everything I told them
