Improper wiring could make the rig key up when plugged in. This takes out the receive.

Thanks to All so far with helping me with the TR-4C troubleshooting chores. Today I wired up the .208 connector to the mic and plugged it in. Now my rx goes deaf when I pulg the mic into the mic jack?? I used a wiring diagram I found on line to wire the mic up. The mic is a Swan branded desk mic made by Shure. I believe it's a Shure 444D model. Anyone have the correct wiring method for these mics? Still puzzles me why this would cut the rx out even wired incorrectly.
