on my 1988 S4 N/A i could lock the passenger door by simply pulling down on the drivers door lock (inside). i tried this with my 1987 TII and i couldnt get it to work. yesterday i was looking at the wiring inside both cars doors and im missing a wire in the TII (the one that doesnt work). im assuming that last wire in the 3 pronged plug is what i need? was this a year specific option or what?? i been searching for hours with no luck.....
also searching in the FSM i had no luck.
maybe i missed that section? if i did could i get a link or some kind of guidance?
thanks.

 

after more searching this is all i found ALMOST usefull for my situation....

so anyone know why my power lock plug only has 2 wires instead if 3? the FAQ says i should have this feature??

 

I didn't see anything in the FAQ about locks, but maybe I'm just blind...

It sounds to me like you just don't have power locks. Do you have a solenoid?

thats where i was reading.
ill have to check for the solenoid.

 

i think it became an option in 88, so 87 wont have it

 

yup, by looking at that it looked like it came out as an option ( on GXLs, TIIs, and Verts) in 88 and wasn't available before that.

 

hmmm....wonder how i can convert it?
