I'm in the middle of installing this system now. I figured the heater holes would get a plug and/or grommet for the many wires still needed to run in and out. It appears the long hard line will help me run under my relocated battery, but I don't know how it will work with yours. Yes, the instructions blow, but the support is pretty good as he^ said! Mine is hooking to a factory '88 5.0 compressor which ads difficulty points not needed on this project. Let us know how it goes!
Did yours come with custom hoses or the kit with all the parts that you use to build your own hoses?
