I apologize for the long post, but I just wanted to clarify everything. Questions are in RED.
Picked this stock head unit up and am attempting to wire it up correctly. It is the Alpine unit with the infrared fader:
The stereo was cut with plugs from one e30 and the harness w/ amp and premium speakers was taken from a different e30 that had radio plugs cut already. I'm trying to connect the harness to the plug leads on the head unit. (yes I realize its really not worth the hassle, but it was mostly free so I'm just going to do it, ok?)
RR: Right Rear - BU/BL
LR: Left Rear - YL/BL
FR: Front Right -
BU - connects to-> BU/RD
BR - connects to->BU/BR (common ground splice)
FL: Front Left -
YL - connects to-> YL/RD
BR - connects to->YL/BR (common ground splice)
Should the Front Plugs have the Brown ground wires there or do they not go into the head unit? Do the Rear Plugs need some Brown grounds too?
MP: Memory Power - YL - plugs to-> RD/GN - from power distribution
IL: Illumination - WT - plugs to-> RD/GY - from power distribution
PA: Power Antenna - WT
G: Ground - BR/BL - from ground distribution
+: Switched Power - VL/GY - from power distribution
??: Unknown - BL/BR - plugs to-> ??
??: Unknown - WT/BR - plugs to-> ??
This plug is hardwired to the back of the head unit: What does this plug connect to?
Thanks for any help, if anything needs clarification please let me know.
