    Does anybody know what the brand and model is for the large connectors used for the sensors/injectors and coils/iac?

    Did more searching and found it - Delphi GT 150

    Hi the15car

    You may care to have a look at this link https://www.autodesk.com/campaigns/f...-for-hobbyists it will give you a free version of Fusion 360 that will work with adobe programs and it will output STEP and IGES files that are industry standard CAD files. There is quite a steep learning curve but YouTube has a lot of tutorials and with a little bit of “focus” you will get the hang of it.

    I made up the adapter seen here using the free version of fusion 360 (which I had 3d printed) so it should work for you ... https://forums.edelbrock.com/forum/p...3711#post33711

    Adobe Illustrator has a useful feature of being able to take a scan of a paper template and trace the outline. It saves it in a vector format and or you can import it as a dxf file into fusion 360. Unless you do this all the time it takes some time to work it all out .... but again YouTube can help.

    I have no commercial interest in this online course, but it might help those using Fusion 360 to 3D Pint parts LINK

    Only thing I wasn’t quite so keen on with Per’s design was that it required a rectangular cut out in the firewall ... I thought at first that was required to get the socket through, but now I see that the split grommet seals work with a 3” circular hole.

    Maybe it would be possible to design your own circular plug that covered the mounting bolts/screws (oval face perhaps) for a clean look and incorporate some sort of grommet (seems absent from Per’s design) to keep engine bay fumes out. Why not go crazy and have a Pro-Flo logo on it?

    What CAD package do you use .... I am messing around with Fusion 360 because it seems good and is free (for personal use) ..... If you get a file you would care to share ... I would like to have a look.
    My son has AutoDesk Inventor through his high school. Still new at it though. Best he's done so far from scratch is a spark plug holder. :-)

    Oh Ok I misunderstood …. 3" External Diameter, 2" Firewall Circular hole, 2 x 1/2" holes for the looms.

    Thanks

    Thank you. Appreciate it!

    Looks like a good answer to the Fire Wall Problem. I see that Seal-It make quite a few of these split grommet seals https://sealsit.com/page/2/?s=split+grommet+seal

    Do you know what the size / # Part Number is of the one that worked for you?

    What sized hole in the Grommet did that give you / what size secondary hole did you cut ?

    Thanks
    I went with the 3" split one with the 1/2" hole, second hole was roughly 1/2" too. Hole I drilled in the firewall was 2"

    Do you recall which tool you had to use to de-pin? Thank you.

    I ran wire harness thru center of firewall and used a Seal-it . I mounted the ecu in the glovebox on my 1965 Mustang.
