[Hallicrafters] wiring d104

[Jack Schrader]

I recently was given a never used amplified d104 that had a 4 pin plug on it.

I want to put on a 2 pin plug so I can use it with the ptt on my sr400, ht44 or my 32b when I get it fixed.

I’m a bit confused with all the wires on the mic cable. Here’s what I have figured out: yellow lead to pin 2, white to pin 1 and the shield to the shell or case. Black, blue and red unused. I want to use the internal pre-amp

Have I done this right?
