For all you 3.2 conversion guys out there. I'm looking for ideas on mounting the ecu and altitude sensor. Under seats, rear trunk I'm open to ideas. I'm assuming that because it's not a sealed unit, that the engine bay is out of the question. I'm having and issue under the seats because I've welded submarine belt bungs to the floor, I've limited my placement options.
Thanks
Dave

I have the Ecu behind the drivers seat. It's held to the backpad with a longer back pad screw. The altitude and DME relay is behind the passenger seat. Didn't have to modify the cables at all.

Are they mounted vertical to the lower firewall?

Dave - I have the interior out of my car. I think I have enough length on the dme harness to run it up the tunnel to the passenger footrest. If that doesn't work, it will probably go in back of the driver seat. I have the fixed passenger seat on my early car.

yes, I am just using one back pad screw to hold it in place flat against the backpad. Works great and the cable is just the right length. I can take pictures later tonight.

I have mine in the center console behind the gauges. easy to get at the dmv relay. Ran the wiring harness under the center tray and above the tunnel.

Thanks for all the feedback. There are some great ideas. Since I widened my Konig seats , I won't be running a backpad. So I was playing with locations last night and came up with this. I will either make a cover or make a custom center console that covers the ECU. I'll mount the altitude sensor and dme relay behind the pass seat. Attached Image

this is what we have done in the past 3.2 conversions
i personally prefer the under dash mounting because it doesn't interfere with anything.

The center seat mounting done here we are going to be building a console for a sub and power window switches so it will be hidden.

This is how we rout the wires through the firewall. this is so your not relying on a grommet to keep water out and it makes removing the engine simple, you do not have to remove the entire harness to drop the motor.

Please be aware that in doing this the wire harness no longer fits in the stock groove and modifications of carpet and/or omissions of center console are necessary.

BTW do you have any more pictures of my car during the time it was spent at Marks shop? I would love to have them.

Mine is behind the passenger seat. Fuse block from a 911 lives there too for fuel pump and key-on ECU circuit. Figure the passengers are often shorter than drivers.

If I can get mine to reach, that's where it will go.

You have to make an extension harness to get it to reach the factory 3.2 harness isn't long enough

Had a feeling. Then It will probably go between the seats or ahead of the shift lever
