Dominator ECU mounting location

[Bad Bowtie]

This is a question for those of you running a Holley Dominator ECU. I am getting around to wiring up the wife's 68 Camaro and I'm looking to get some ideas on where most of you guys have mounted the ECU. I was planning on the space behind the glove box but have come to realize that real estate gets eat up pretty good by the Gen IV Vintage Air evaporator and the duct hoses. I really don't want it under the hood as I'm going for a "clean" look under the hood. You wont see the MSD box or MSD coil under there. I am testing the thought of bringing the wiring in along the lower portion of the firewall where most people place the AC/Heater hoses in the vertical position and put it just below that bulkhead.

Would anyone care to share where they have had success placing this ECU. All comments welcomed

Thanks
