Ok, found one. Low side port is circled in yellow, high is circled in blue.

Also for what its worth, I just recently converted from an empty r12 system to a good running COLD blowing r134 system and can confirm that my ports were where they are in the pic I posted. TT's might be different.

NA/TT hi side is in similar locations. The low side differs, TT low side is near the battery tray.

As shown in your pic, NA is near the front. This is because of the intercooloer piping that runs in the front area for TT.

Yep. I was just WAY off yesterday. I read High side, but was thinking low side and of course the whole NA/TT thing. Sorry. Ill read better next time.
