Where to install a Reverant MS3 Basic in a 99
So the stock 99 ecu sits above the clutch and brake pedal. The MS3 basic is is more than twice the size of the stock ecu though... I don't see how it could fit anywhere near the drivers feet where the harness will reach. Has anyone installed an MS3 basic in a 99? If so where did you put it? At this point my only idea is to find the stock connecters and make an extension harness to put it behind the glove box.
Wut do? Also I'll try to get some pics of the problem tonight I'm on my phone now. |

I'm going behind the glove box. Boomslang made me a extension harness for the one that isn't long enough. Mine is 48in and was about $100, but a 36in would work and be cheaper. I err'd on the long side since I think I'm the first going this route. The two green ecu connectors that are engine harness will route far enough to work.

Should eliminate the need to fiddle around with wired ecu connections. https://www.miataturbo.net/attachmen...ine=1379805715 Attachment 239495 Haven't done mounting yet. Semester started and mildly lost interest in my slow going project. |
My ms2 has a small harness cause it goes db37 to Miata stock harness. My ms2 is zip tied to the steering column kind of...
Ms3 looks way bigger, and I really dig the way you cut that hole in the side of the interior panel for the USB port. That is win all over. |

Semester started and mildly lost interest in my slow going project. I found this m.net thread with the part numbers for the stock connectors, I'll look into if they are correct or not later. Right now it's time to drink my sorrows away. Thanks again TZ, great pics. Oh and thirdgen I think that cutout is already there isn't it? |
Reverant sent me a picture of one installed next to the steering column. Unfortunately, I did not save it. Perhaps he will post it here?
|
Yeah that cutout is already there. Never thought to use it as a USB jack, though, awesome idea! I need to do that for my NB.
As for the MS3... i dont think there's any GOOD way that this thing is fitting on the driver's side. It's HUGE. It really needs to be mounted Hydra-style with a patch harness. |

He has the breakout harness on the other end, though. I shoved it up there but with engine harness on one side, breakout on the other, it wasn't going to work real well.
|
I'll bring everything back over after grabbing some food and we'll give it another shot. But we'll start with the ECU this time lol.

He removed the black cover on the DB37 connector and insulated any bare contacts with electrical tape.

Awesome, I will try that, I could almost get it in that spot, but the DB37 was right up against the firewall.
The main problem appears to be the white plug seen in picture 2. https://www.miataturbo.net/attachmen...ine=1379878068 https://www.miataturbo.net/attachmen...ine=1379878068 Anyone know what that is? I guess I could have looked while I was under there. I might see how much room I have to move it out of the way. I powered up the MS3 and calibrated my TPS at least. |

I have a DIYPNP, but that appears to be of similar size. I got tired of installing and pulling it from the clutch/brake location... here's what I did:

The ms3 won't fit in that location.

diypnp is way way smaller aaron
My solution might also be not relevant to thread :giggle::party: https://www.miataturbo.net/attachmen...ine=1379914828 |
It's just too wide to fit in there Aaron. And don't think I didn't try, I'm quite good at fitting wide things into tight spaces :giggle:
|
For instance, the MS3 WILL fit in his anus. Really the hardest part about that install was figuring out how to feed the factory plugs up through the seat.

I already sent these photos to concealer but this is what I came up with to mount my ms2e.
Basically just made an aluminium bracket that bolts in to the oem ecu's bracket bolt and runs across to near the fuse box and the ms2 sits ontop. Then I just ran the serial cable out the fuse box. |
If I wanted to not hack it together, I would have done something like that. For now I will save the nice mounting options until I put it behind the glovebox with an extension harness.
I'll take some pics of the hack job at lunch. We got it up there and installed. |
