Once the lines and mounting brackets are fitted the unit can be mounted in the cab. Ideally this is a two person job. I was by myself and with the right amount of cursing, I got it in nice and level.
Before actually mounting the ac unit, a block off plate is screwed to the passenger side kick panel vent opening -
After that is the ac unit fitted to the firewall -
Here is a photo of the Howell Fuel Injection harness I'm using -
With the ac unit in place I could find a good place for the engine ecm harness to enter the cab. I decided to make the hole next to the ac/heater port opening. I used a Ron Francis ecm harness firewall grommet in the opening.
The ac unit itself provided a good spot to mount the computer. The upper mounting bracket has a nice flat surface and I used 15lb rated Velcro to hold the ecm in place. The entry point for the harness is neatly hidden behind the ac unit and routes over the top to connect to the ecm.
