I think I'm going to add a console box light (that was an oversight ), and a 12V cooling fan to draw air through the console to cool the Holley ECM and over the amp under the rear seat. The amp needs a minimum of 1" airspace above it and that's what I have. The amp is a lot thicker than I thought it would be at 2" and I thought I had more room under the rear seat. Building the mounting bracket for it was a pain since it pretty much had to sit on the floor, and I didn't want any screws going through the floorpan so it attaches to the rear seat bottom frame.
I ordered a few auxiliary outlets with audio connections and USB so I can plug in an iphone, ipod or whatever and charge my phone. There's also a couple of switches I need to figure out a location for that are used to set the VHX computer, start a datalog in the ECM, and a valet switch for the alarm system. The alarm also has a blinking LED when it's armed so that has to go somewhere. Lots of little stuff like that to figure out. I don't think there's room for cupholders anywhere.
