Heys guys I am looking for any advice on where to mount the Terminator X inside my 73 Duster. I don't want it in the engine compartment. I've heard next to the heater box. But maybe more importantly want the most ideal spot to go through the firewall. Has anyone done this?
 
I've looked a little bit into this one before on a different project. I don't know about your '73 but the pass through on the driver side for the foot washer pump or speedo cable looks like it may be a viable starting point for this setup as a pass through if your going to use the Holley dash setup.

Here is what I did on my 71 Demon 392 swap. 2" hole and a Jegs 2" grommet in the recessed area under the wiper motor. I have an aftermarket heater/AC box so my location may not work for everyone. The harness will come out behind the intake and on the inside I'm going to run it under the passenger seat where ill have the Terminator ECU, injector drivers and dash module mounted to an Aluminum plate. In the second picture if you look carefully you can see the grommet riveted in place

If you have an automatic, therefore the clutch pushrod hole is plugged, I was able to get my HP connectors fished through there. It is over at far left of firewall, an oblong plug
