Good by A/C...but what about these wires!!!!

[The Struggle]

Hey guys!

I have the left over remanence of my a/c system to deal with. Does anyone know of a decent thread or idea of which wires to remove from the engine bay/fire wall? I'm keeping the heater core, but no A/C so I can clean up the engine bay and utilize a few Ponies for my build. Any advice would be greatly appreciated!

Welcome aboard Blaine. Are you replacing everything with heater only parts or just cutting the ac stuff out and using the existing ductwork/housings/controls etc.?

I did an AC delete on my Burb and installed a heater only setup out of another truck. It really cleans up the firewall and dash and makes a lot more room and has simpler wiring and controls. You just need to find the donor parts at a junk yard. This required welding some sheet metal in to cover the hole for the AC intake hole in the firewall and relocate the holes for the heater hoses but ti's pretty simple if you are a do it yourselfer and have the tools.


Here is a pic of it during the install. Both AC and Non-AC harnesses fit the same hole in the firewall.

Thanks for the info paw paw I believe this is exactly what I need. I won't be welding any since I don't have a welder. Probably cut up some aluminum and rivet it up. Keeping the original core and supporting parts, but the a/c and all its buddies are goners. I'm looking for that simple, clean and organized engine bay.

Yup rivets or self tappers. And caulk for the seams. That sheet metal I used on mine is from Home Depot and the thick stuff I think it's around 9 or 10 bucks for a sheet 12" x 18" or something like that. Use a cut off wheel on an angle grinder to get the shape you want.
