Purchased an a/c recharge kit to boost my a/c and I am having trouble finding the low side port I think? I found the large aluminum pipe running to the compressor(the one that gets cold) and the kit would not fit. the port on the car has a pin in the middle of it and the recharge kit connector also has a pin in the middle also so Im stumped. The only other port is way too small to fit so Im stumped............

any help is appreciated

 

i have a 2001 the low side port is always the larger of the two its located on the top left side above the windshield washer fluid...

if anyone knows how to get a ac low pressure line can you let me know... thanks you

 

I had a similar problem with my 84 Cordia and ended up buying a set of adapters from Aliexpress (China) for approx $24NZ. Now the canister top-up system fits ok.
