I would like some help in identifying a couple of electric plugs on my 97 psd.They are just below the ashtray on the bottom of the dash,one points to the left the other to the right,and they are not plugged into anything.they are also just to the left of the data port.Does anyone know what these are for?Thanks and Merry Christmas to everyone!!Pike

 

could you post a picture of them for easier identification?

 

The one marked data port is for the OBDII connection. The one port is it kinda round? Sounds like where the AIC plugs in, I belive it points left...don't remeber

 

The one below the ashtray is where the one for my electric trailer brake controler is at.

 

Correct the one on the left that points twards the drivers side is for the electric trailer brakes. I dunno what the other ones is for. AIC (Auxilary Idle Control) maybe?

 

Thanks for all the answers.I just noticed them when I was hooking up something else ,thanks agian Pike.

 

One could be for the buzzer, does a buzzer sound off with door open and key in ignition if not someone did you a favor by removing it.

 

there is also one right by the data port for your psom ground so you can program it

 

Yes, it is for AIC, I had it installed on my '97.

 

Is this so you can install a high idle. My 97' does not have one.

 

yeah the aic is an option. You will find it mainly on service trucks and such.
