Taking a break from working on my Healey, my daughter brought over her 1990 Cadillac Seville and asked me to top off her A/C. She gets a message that the system is low. I still have a can of R-12 refrigerent in my garage. Now all I have to do is remember where to hook it up. There are two A/C fittings on the Caddy. One is by the firewall and one is on the dryer/accumulator. I know you want to hook up to the low pressure side, but I am unsure which is which. Anyone on the forum familiar with the older R-12 Caddy A/C system. Thanks.
 
Large diameter hose is low pressure. Also, Hi pressure hose routes forward to condensor, Lo pressure goes to firewall/evaporator. A final note, you *may* need to clear the code stored for lo pressure before the system will work again.
