Dave and I have been sharing the ideas for a while now. I didn't think up doing it this way, but copied what Joe Lutz had done at his shop Hot Rod Dynamics build he did right here on so I am more than willing to share the ideas with Dave or any others. I used Joe's firewall and inner fender wells to make sure it worked.

Joe's build is here

Mine is here

I used a rubber block, drilled for the hoses and split, to seal the front opening in the wheel well. I also put a shield over the electronics so if any water got past the fender seal it's not as likely to get them wet.

Don- your ingenuity never ceases to amaze me.

I located mine on behind the removable right side wheel house lower panel and have lived to regret it. Am chasing a phantom engine control harness problem and although accessing the ECU isn't too difficult the harness connectors and adjacent harness are really difficult to access. In fact it looks like I'm going to have to remove the fender!
Nobody to blame but myself and I rank that decision as about the worst one I made when installing my 5.3. I don't know where the best location is but wouldn't recommend the one I chose.

Default Inside under front seat

I used a PCM mount from an S10 for my 2004 computer. It clips into place and has a metal lever to additional security. My fuse box is right next to the pcm. All of this fit without any clearance issues right under the front seat under the driver. The TAC module for the DBW is also nearby on the passenger side. No issues and easy to work on from above.

I found a PCM mount on eBay (don't recall what it supposedly came from). Mounted it in the passenger kick panel area (this pic was while work was in progress):



The PCM and harness came from a van, so the harness length was pretty long. I shortened a bunch of wires, but also still had to lengthen some. Of course, a good bit were deleted, too.



I've deleted heater, so I fab'd a plate from 6 ga sheet metal for the harness pass-through, which doubles as a fuse/relay mount.



I know I'm a hack compared to the beautiful work these other guys do, but it's primary life is at the track. I may eventually clean it up some more (especially if I decide to put the heater back in - driving home from the track in a driving rain storm on a cool spring day can make a defroster desirable). I'd probably keep the PCM location the same and relocate the pass-through.

Will someone enlighten me on the Proper Spelling and definition of ECU.
I was assuming it had something to do with an Electronic Control Unit.
Maybe I should have taken advantage of a Higher Education but it was not to Be!

That post was worse than a political post that I don't agree with, a "greeter" post, or a "nice car" post when the car isn't nice.

May have been "lighthearted" to you, but missed the mark by 1000 miles to me.

Shame on you.
