That is an interesting idea. I already have two wires for the neutral safety switch routed through one of the rubber plugs in the firewall (not how I set it up...somebody else did that for me, aaahhh!). Could probably take the same approach for the ECU.

If you have 4 or 5 unused ports available in the OEM bulkhead connector. I personally don't want more troubleshooting, R&R, labor under the dash. I certainly wouldn't want the ballast resistor under the dash as described above. It gets extremely hot.
