Have a Radio/stereo/cd from 2004 silverado. GM part no. 10357894 , Delphi Part No. 12244929 . I can't get the radio to light up or show me LOC message. Pin Outs are as follows for the 24 pin plug.
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.?
