I’m using an AAW Classic Upgrade harness in my Australian 70 Valiant Hardtop (AKA Dart) as well!
The factory didn’t use a bulkhead connector here in Aus, they hardly even had a fuse (just 2) LOL!
I’ve hooked up my fuse block on a custom bracket I made out of 3mm (1/8”) plate which is mounted to the steering column support bracket. Apologies for the poor photo but you should be able to just make out the fuse block above the shifter. I’ve also included a cutting profile image of the mounting bracket below, I’d be happy to email you a .dxf CAD file of this if you think you may like to get one laser cut. Battery is in the trunk / boot as well and interestingly I’m also going to use a ProFlo4. I’ve mounted the ECU along with starter relay etc on another custom plate which mounts to the underside of the dash and then passed the ECU / Injector connectors back through the firewall where the heater tubes pass through. I’ve managed to hide most wiring under guards etc and have had to do a fair bit of custom wiring to “Australianise” it all and make it work with my custom dash below. Probably have another week or two’s work to finish off the wiring and get the dash back in.
