I have not done any testing with the PDM 25, but as I understand it, it works with the Holley CAN. The PDM 25 uses slightly different software than the PDM 28. After PRI I am headed to Wisconsin for a little bit, but once I am back home, I can hook up the PDM 25 and do some testing.

Having a 3D scanner and a competent designer on call has really improved the overall quality of this build. I also want to thank Brian Wolf from Send Cut Send for helping out with this particular project.
I started with a 3D scan of the glovebox area without the glovebox. We obtained models of the Dominator and the Hardwire PDM from Holley and Hardwire and they were used to mock-up a mounting solution.
I wanted the LEDs on the PDM to be easily visible and I wanted the connectors to also be easily accessible. The tandem stacked arrangement is what we came up with.
James created the DXF files with SolidWorks and I uploaded them to Send Cut Send. They not only did the laser cutting but also the bending. Today I finally got the package after a bit of a delay due to the weather.
I expected to have to do some fiddling around with the bracket to get it to fit, but it dropped right in. The 3 holes that hold the glove box door lined up perfectly, as did the two slots up at the top.
I couldn't be happier with this solution.

I am making slow progress. In the last installment I posted the bracket that will hold the Holley Dominator ECU and the Hardwire PDM. Today I got a care package from McMaster Carr with some hardware.
The Dominator case is not supposed to be grounded to the car chassis. It actually has plastic and rubber mounts that are already inserted into the case. However, to isolate it more, I used rubber nut threaded inserts. To fasten the auxiliary bracket to the main bracket I used U-nuts.
Here you can see how it all fits together.
Unfortunately, the holes in the PDM are too small for #10 screws, so I have to #8 screws and corresponding U-nuts. I used a temporary support for picture purposes. LOL

A 3d scanner is very convenient, but you could still just take measurements the old fashioned way and CAD a design. I don't have a good enough reason to pay for solidworks, so I have been using the latest release of freecad lately. It is plenty capable for this sort of design.

All of this can definitely be done without a 3D scanner or even without CAD. Careful measurements and old fashioned CAD (cardboard aided design) can get the same results. Solidworks is also not necessary and there are other tools, like Fusion 360 which are free.
