OEM electrical connectors?
Hello, been searching the site and cannot find info for sourcing a new BAC connector for my S4 T2 harness. I found info for FD connectors but not FC. Anyone know where to source these? I leave in a month for the Army and need to get the car to hold idle so i can smog it. Thanks in advance for any help.

@ kompressorlogic-looking like i may have to do just that.
Honestly i'm not even 100% sure that is my problem. She won't idle cold and once she is warm she hunts from 300 or 400 rpm to 1200 or so. Also, she bucks under load below 2500rpm. needs to be fixed regardless though.

The BAC connector for the S4's is basically the same as the fuel injector & coolant temp sensor plug. With a little shaving to the BAC plug, this will work fine:

hmm things to look at is the tps set correctly? have you tried adjusting the idle rich/lean screw ( black thing by the boost sensor near shock tower). 1200 warm is too high the throttle cable isnt too tight is it? also is the throttle stop adjusted correctly? theres also a screw in teh bac u can adjust for air bypass also, then another one that can cause it to be to high is thermowax adjusted wrong, or a vacume leaks as well.
is it an even pulse back and forth on the idle, or just kind of randomly lumpy all over the place?
if idle is too high it can cause the idle to pulse like go back and forth between 1500-1000 or something of that nature because it goes out of the idle circuit and into the deacell circuit and back and forth...things that can cause that are anythign thats holding throttle open, stop screw, cable,bac
a real lumpy random idle can be vacume leaks,adjusted to lean, cracked turbo inlet duct.
if you dont have experience adjusting any of these i would research in the factory service manual, because if u odnt know hwo to adjust them u can easily make things worse...

Make your own out of 14-16 spades, just be sure to plug them into the right spots.
Heat shrink and be done. I do recommend you source the appropriate connector at some point, although it isn't really necessary.
