Help with AEM 30-0310

Hi all I am definitely new to all of this and any help would be greatly appreciated. I recently installed a AEM 30-0310 wideband sensor and I cant for the life of me figure out how to make everything work together. I watched a few videos and it helped a little but nothing seems to be working. No matter what I do all I can get it to read is between 18.3 and 18.6 and it doesn't matter if its in the exhaust or not which is kind of telling me I have it all set up wrong. The aem sensors that come preinstalled in the hp tuners software don't seem to work and I cant seem to figure out how to adjust everything to get it right. Any help would be greatly appreciated. Thanks in advance.

Are you using the analog or serial output on the 0310, and what do you have it connected to?

I?m using the serial outport and it?s connected to the 5v outport. So basically It?s connect to the number 1 pin on the serial port and then I have the ground on the number 5 pin on the serial port.

Should be RX to pin 2, GND to pin 5.
