Looking at it from with the 12 pins to the top B is on left and A on the right.
12-b------Park 12A -------GND
11 -------RF + 11 --------RR +
10 RF - 10---------RR-
9-------LR- 9---------LF -
8 LR+ 8---------LF +
7 RUI 2 7---------RUI 1
6 AMP Mute 6---------RUI REF OUT
5 N/C 5---------ANT GND
4 DIM + 4---------FM DET
3 SW 12V OUT 3---------RSA Enable
2 IGN 12 V 2---------CLASS 2 B
1 BATT 12 V 1---------CLASS 2 A
I have wired this up on bench with battery and 4 speakers, both 12v Batt and IGN. and GND. I get no response from radio but the clock and the cd player operate. Any ideas on why no power is getting to radio section.?

I'm not sure where you got that info, but I have attached the standard pinout info for a Delphi Class 2 head unit from Delphi themselves.
Also, remember, to get it to power up through the 12V ignition, you must dis-engage that pin on that EEprom first. With this pin engaged, it causes the head unit to be powered on only when given permission by the data buss.
I hope this helps.
