Any pictures or ideas on mounting computer inside car 70duster also mounting aftermarket air thanks in advance
 
What type of computer? If it is a small one like FAST uses, it can probably go behind the glove box, if it is a larger one like the Holley HP you are going to have to be creative depending on what you want (see it or not). I have a Holley unit in my 70 Challenger and it is mounted above the inner fender brace inside the drivers side fender. Its water proof so it can live there. On my Cuda I mounted it behind my glove box (FAST unit).
 
Thanks I purchased the plug and play from mopar just seeing how other people ran wiring through firewall and mounted computer thanks
 
I mounted mine on the driver's side after removing the air box and blocking off the hole run the main harness to the right side of the trans hump about 6" higher than the hump ran all the main plugs above well through the hole that's center with the column near the firewall you have to make the hole slightly larger to get the plugs through everything is hidden and fits great good luck !
 
Be careful of grounding. Unfortunately the "chopped up" nature of current service manuals makes it more difficult to "view" the big picture of a harness. But you don't want to just slop the computer / harness grounds down "anywhere" you can generate what is known as a ground loop, and introduce unwanted noise/ false triggers, etc, there are several issues. In other words try and research the original harness and duplicate that. If nothing else, run a dedicated ground of sufficient size clear to the battery. If the harness / computer EG uses say, a no14 for that ground, and you need to lengthen, I'd use at least 10 from there. Run the grounding wire close to the firewall / other body metal to sort of "shield" it. (Ground plane)

For electronics, it would be best to visualize a "single point ground."
 
I mounted mine in glove box with aluminum flat stock 1” wide and the relays behind the kick panel.
 
Here's what I did.
