Where is the ALDL connector?

I read through as many old posts as I could. I can't seem to figure out WHERE the ALDL connector is to test why my truck has developed a high idle. Would this code thingy be a good place to start? No check engine light is on. Thanks.

It is located under the dash by your left knee. If you take a look it will be staring right at you.

and im just going to guess that the high idle is due to a vacuum leak

Thanks banana avatar guy. I'll look for vacuum leaks tomorrow. Thanks 4x4high, I'll look for the AlDL connection by my left knee.

haha i have no idea how i ended up with the banana... but anyways. spray some brake clean or such around the throttle body, vacuum lines... listen to idle. ive seen this symtom many many times
