1996 Mazda b2300 gem module issue

I have 96 mazda b2300 that is having several issues. All seem to be pointing to the gem module (door ajar bell keeps going, speedo doesn't work, wipers don't work, a bell goes off everytime i start it, etc) I have changed the wiper motor...checked for power to it and power to switch all good. If I unplug one connector to gem the door ajar bell stops. I got a gem mod from a junk yard and didn't fix the problems. Not sure if bad mod or what the problem is now. It won't pass inspection due to a speed sensor code. Is there anything special I must do when I change the gem? Maybe I didn't do it right or there more I have to do?

Welcome to the forums,

You might need to have Ford reprogram that GEM module (and, in some cases, they'll need to have the old GEM module).
