HCN4033a A3 Clamshell Control Head to Maratrac

[wcsd106]

Hello,

I have been playing with a newly-acquired Motorola Maratrac VHF High band radio. My key finally arrived yesterday and I'm ready to get it read and programmed. I did have a question though.

The control head is a HCN4033a. (A3 Clamshell 8 Mode with Scan)

Does ANYONE have the pinout for the connections in the back? I have looked through the Motorola manual to the Maratrac and did not find a pinout for the connections. Specifically, I'm looking for where the microphone hanger scan wires connect as well as the power wire for the radio control/receiver, but an understanding of what each control wire was going to would be very helpful.

I did notice that the A3 had that came with this radio has a switch has had a small toggle switch mounted on the right side and is labeled ON/OFF.. I suppose I'm going to have to open the head up to see what exactly this switch is intended for. (I'll post pictures of it later)

Anyway, any help you may be able to provide will be greatly appreciated. It is my intention to get this radio up on the bench this weekend for programming/testing. Thank You.

The control head schematic is on page 23 of the manual.
