Works perfectly. Note that T3983001 is the only number you need to worry about matching. The bottom number appears to be the batch number or something. As I had already replaced one of these modules under the dash I decided to replace the other one (on the passenger side) so I ordered two of these modules. They came with different bottom numbers, but the top number T3983001 was the same on each device. Both work great! A little tedious to install, but there are some good tips on YouTube. Much luck!
