I am looking for what the service manual calls TAC unit. It is the control module that is under the driver seat on my 89 conquest. Mine allows the windows to work after the 20 sec timer should halt window operation so the window relay is picked all the time and if the car sits for several days the battery runs down. My other 89 conquest works fine so would you have this module and how much do you have to have for it. PN# on my module is MB606956, Type G8C-07M, No. 004490 OMRON Japan.
