Hello!

I have a S4 NA to TII conversion, and im using the original NA harness.

I found a wire that isnt plugged into anything on my passenger side of the vehicle close to the MAF and the Pressure sensor. (I will replace the 2 prong connecter with a new one tomorrow) It looks like its Red/ Yellow on the top and Black and Blue on the bottom and it comes from the front of the car going towards the passenger side of the engine. I've been looking in the FSM for where it goes to but its kind of difficult for me to understand it. I think it is F-67 Vacuum Switch, but i'm not sure!. Does it plug into the yellow connector on the main harness!?


ANyway, if someone could direct me to where it goes, I'd greatly appreciate it!

Thanks!

 

Correct, diagram says it's for the vacuum switch. It's only for automatics.
Yellow is the fuel pump check connector. Leave it unplugged unless doing diagnostics.

 

Thank you for the response, I have left it unplugged
