ECM removal

Hey guys. Yet another dumb question. I am trying to get the ECM out of my 91 RS to see if it was swapped when the previous owner put in the 350. I found it in the passenger side kick panel and it is in a yellowish plastic bracket. I removed the screws that hold the bracket in place and that let it drop down a few inches. I can't figure out from there how to get the ECM out. I felt around trying to remove connectors to free it up and none came loose easily. I can see some electrical tape on the wire bundle at the top so I am afraid there is some kind of hack job that I am going to pull apart.

I also tryed to pull the metal case out of the plastic bracket with no luck. I am probably missing something obvious here, but I don't want to force things.

Whats the trick to getting them out? Shoud I be trying to remove teh metal case from the plastic frame, or trying to oull hte whole thing out together?

Are there any screws etc holding the metal case directly to the pastic bracket, or do I just bend the tabs and slide it ou. Should I be trying to pull it straight down to get it out? Again, i tried nd felt like I was going to break something. Thanks for the quick reply.

Re: ECM removal

NOw htat I have the ECM out this seems like a really stupid question. but, here's why.

The plastic frame was stuck because some unrelated wires had gotten looped thru it. And, I cuoldn't pull the ECM out because it was glued into the plastic frame by some thick black putyy or glue. I guess tehy probably came from the factory like this. Took a lot of effort to ri it out. The access panel over teh chip also seemed to be held on by an adhesive and I had to pry it up with a screwdriver. I can only guess this all means it hadn't been opened since it left the factory. ANyway, thanks for the help!
