I bought a conversion kit to switch over to R-134 for my '93 SC400. I did a search and cannot find any info as to the location of the high and low pressure service ports. Any one have pictures or detailed instructions as to where the components and service ports of the AC are located?
Thanks,
Sean.

hmmm,
dunno, but give this a shot,
(someone told me the plumbling routes were similar in the SC3 and SC4)

In my SC300,
the low side is on the passeneger side engine bay, near the firewall.
You have to reach down about 10"
it's pretty much right in front of the passenger side of the windshield.
there's a small gray plastic cap, it's marker with the letter "L"
the cap unscrews to reveal the port

hope that helps
regards
Ken
