I also wanted to re-locate the charging ports to make that task easier.
I added T-fittings to both lines coming off the compressor and connected them two fittings installed in the firewall.
For the firewall fittings, I used the T-fittings that are now usually screwed into the back of modern compressors. You will see I capped off the outlets that usually fed in to the refrigerant hoses.
all I have to do is pull the upholstered cover and there they are.
