I also made my own ABS sensor brackets for the rear to fit on my NA hubs that don't have provision for a sensor
For the front I used NB ABS hubs and simply plugged then drilled and tapped a new mounting bolt hole and spaced the sensor out to line up with the tone ring.
You also need to use long thread brake flare nuts in the module, the short ones run out of thread before the pipe seats, found this out the hard way.
First off, thanks for sharing, amazing work.
Do you know how short the fittings were that didnt work? The "short" and "long" fitting lengths differ from manufacturers so it's hard to tell what those actually mean. Also, I assume inverted flare in the tee fittings/blocks? Lastly, when you say "hubs" you mean the uprights right?

Sorry yes I meant uprights not hubs
I bought all the fittings from Brakeconnect.com and I found that the BQ4511 was too short but the BQ4511LT fit great not sure what the exact lengths were, all the tee fittings and joiners are inverted flare M10x1, the tee blocks I bought from ebay.

How big of a gap are you running between the tone ring and the sensor?
Part numbers are brakequip bq44 for the pressure sensor adapters and bq91A tee fitting. 2 of each
Other than that you need M10 inverted flare tube nuts (about 12) and M10 (2) and M12 (4) bubble flare tube nuts and a few M10 unions (3)
I saw the:
2x Brakequip BQ44
2x Brakequip BQ91A
Then I noticed the post above talking about the length of the M10 nuts so it sounds like I'd want to order:
12x Brakequip BQ4511LT 3/16 M10x1.0 long bubble flare tube nuts 4x Brakequip BQ9180 3/16 M12x1.0 bubble flare tube nuts 3x Doorman 785-439D Bubble Flare 3/16 M10x1.0 unions
I ordered my 3DM harness yesterday so I'm trying to gather everything without making a ton of orders.
The OEM rear sensor mounting brackets are steel and so heavy thus not worth modifying. I just cut new brackets out of aluminum. So much lighter. A fifth of the weight. I should anodize them next

You only need the long thread M10 nuts for the ports in the control unit but doesn't hurt to use them elsewhere.
You also don't need bubble flare unions, inverted flare unions are probably easier to use and matches the rest of the Mazda fittings.
Stock setup also only has one rear brake line which feeds both rear brakes so you need to add an additional line from the ABS unit to the rear of the car,
I used the factory line to feed the LH caliper and ran a new line to the RH side.
I sure can but it won't be cheap since I have to spend time on it which I could dedicated on something else.
If that doesn't put you off you DM me I guess.

On the easier to use part - any input on why that? I've used both inverted flare and bubble flare unions over the years but I haven't experience one being any different to use than the other. I might've missed something.
