gmrulz4u Posted October 12, 2003 Report Posted October 12, 2003 I was recently doing some regular checks on my 89 Cutlass(2.8) and when I was checking the vacuum to the transmission modulator, I could see a white colored plug under the intake air box. It was a 3 socket female plug. There was nothing plugged into it, and so I was wondering if anyone knows what exactly it's there for? THANKS! Quote

THANKS! does it lead to the harness up near the IAT sensor(if you have one? I've never worked on 89 so I personally do not know)? if so, it's probably just the test port, there are a few in pretty much every car w/ a computer for various testing purposes. Quote
PaPaPooh Posted October 13, 2003 Report Posted October 13, 2003 i have seen it on my car and it has a plug on it i was at school and saw one on the bench thought to my self "that looks just like mine" so i checked and it was just like mine im not sure what it is for but mine did have a plug in it Quote
gmrulz4u Posted October 13, 2003 Author Report Posted October 13, 2003 I BELIEVE that this pic shows the plug that I am referring to: I am going back out tonight to check and make sure that this plug was the one that had nothing connected to it... Quote
