1990 LS400 A/C recharge
 

I bought a couple of R12 from E-bay and am ready to recharge the A/C of my 1990 LS400. Need some specific help:

1. Where's exactly the low-pressure connector for recharging?
2. Where is the side galss to check for bubble?
3. How much R12 should I add on?
4. If someone else had done so, any specific advice?

Thanks!

I'm in ther same boat... anyone know?

I just sold my '91 LS400 and as I remember, the low side connector was on the left side of the firewall looking from the front of the engine and the sight glass was in front of the radiator on the left side, also. Try one can and then check for bubbles. I had converted my '91 to the new refrigerant and it worked great at about one-third the cost of R12. Good luck!
