Maxtrac 900 Trunking/Conventional

Does anyone happen to have a service manual for this radio?

I am having trouble with the radio, using the 16 pin connector. I had thought, reading the Maxtrac page here, that all of the full 16 pin logic boards had the ability to program output on pins 8 and 14 with the RSS software. Unfortunately, the two radios I have only allow programming public address on pin 14. I need to find where I can jump "PL/DPL/CSQ Detect" signal to pin 8 on these radios. Does anyone know off-hand where I can jump this, or where there may be spot on the net that has the proper scematics and such? Thanks

If I remember the trunking radios did not have the same accessory jack options, like TOS/COS ect;. When making my RICK repeater modules up, I have to take this into account.
Just like the five pin logic boards on other Maxtrac/Radius radios, a jumper has to soldered in to route the COS/TOS signal to the outside world.

Yes! Ant the question is: Where can I get the PL/DPL/CSQ detect off the logic board of the Motorola 900 Mhz B7 Maxtrac?? Someone must have a schematic out there..... somewhere.
