Ok, in 1994 the connector was called an ALDL connector it doesnt look like an OBD 1 or OBD 2 system connector. It should be have two screws securing it to the bottom of the dash, but it has been my experince that most times they are never put back in their proper place after work has been under the dash so reach up under and feel around. The connector you are looking for will be about 1.5 inches long and 3/8 inches wide it will have two rows of 6 openings. Hope this helps good luck on your hunt.

Where is the 1993 Chevy S10 pickup truck low side port

The low side port is in the low side line from the AC compressor, this is the larger of the two lines from the compressor. The charging hose will not hook up to the wrong port as they are completely different.

Looking for the a/c low servic port on a 2006 ford five hundred. I think i located it under the cowling up against the fire wall on the passenger side. Not sure though.

Hi, if the port you see is along the line that runs from the firewall to the compressor, then you have the right port. The high pressure port is a larger port, and your charging hose will not fit on the high side port.

Want to add refrigerant. air conditioner not very cool. which is low pressure port for adding r134a coolant?

The newer cars have 2 ports. The large port which is the high side and small port, low side. The kit you buy to refill the air cond will fit only one of the ports and that's the small port. You don't want to hook up on the high side so, this is why ports are sized and the gauge will only fit one. The low side should be near the evaporator or on the evaporator.

Need to see a picture of high and low ports and their locations on a silverado pickup. can only find two ports on the same line -one smaller than the other.

That's them, and only ones, there's an orfic tube in between both ports in the line, that's what changes the pressure from high to low, from one end of the orfic tube to the other, the small port will be the low side, that the one you recharge in, and the big one is high side.Hope this was very helpful.

I have a 2002 Impala 3.8L
There is one port between the air filter box and strut tower (driver's side). I'm pretty sure that's the low pressure port.
The high port is against the firewall behind the engine, about in the middle.
The ports are covered by black caps.

Finding the correct port for the AC refiller

There are two ports, high pressure and low pressure.
The low pressure is the one you need, The port is smaller than the high pressure and should have a blue cap on it. The high pressure has a red cap. I don't have my manual at the moment,so I can't tell you exactly where it is, all I can tell you is to follow the other pipe till you come to that port. Some are not easily to find. It might also be on the low side of the compressor.

Where is low side port for recharging a/c. on my 1997 s10. I found 2 ports one on the accumulator and one on the tube, however my charging kit port only fit the port on the accumulator. I assume this port...

The port on the accumulator is the low side. The high side port is smaller than the low side. The low side port is the one that gets cold when the compressor is running.
