Anyone have a an Electrical Diagram of the wire harness that is legible for the 89 Vert Bose Radio hookup.

e.g. which wire goes to which speaker etc.
 
I presume your 89 still has the Bose cassette with 12 Pin setup (I just went thru this week the hard way. I just swapped out a Bose CD with my Bose Cassette.). Although my 89 is a coupe, you should have six plug connectors. The 1st 4 are for Delco radio hookup. The last two are uniques for Bose (Your radio will have two wires coming out from side - 1 pink and 1 black sheild wire with ground).

1) Blue plug (Rear Speakers) with:
Pin A Rt Rear Spkr (-) w/ Lt Blue Wire
Pin B Lt Rear Spkr (-) w/ Yellow Wire
Pin C Rt Rear Spkr (+) w/ Dk Blue Wire
Pin D Lt Rear Spkr (+) w/ Brown (Clear) Wire
2) White Plug (Front Speakers)
Pin E Lt Rear Spkr (+) w/ Tan Wire
Pin F Rt Rear Spkr (+) w/ Lt Green Wire
Pin G Lt Rear Spkr (-) w/ Lt Gray Wire
Pin H Rt Rear Spkr (-) w/ Dk Green Wire
3) Black Plug (Power & Ant)
Pin I Pwr Antenna Turn On w/ Pink Wire
Pin J 12 volt Ignition Wire w/ Yellow wire
Pin K Headlight Dimmer w/ Gray Wire
Pin L Ground w/ Black Wire
4) White Plug (Radio Display & Clock Battery)
Pin M 12 Volt Battery Wire w/ Orange Wire
Pin N Brown wire
5) Bose Relay
Single Pin w/ Single Pink wire
6) ??? (Never figured this one out)
Single Gray & White wire (Always hot)

If you figure ever figure out what the last wire does - let me know. Curiousity is killing me!

Good luck!
 
Thank You I am sure this will help me out this weekend
 
It is a Pioneer DEH-P76DH AM/FM CD Player. It was an easy installation after figuring out the wires.

I too did not use the gray wire.
