I saw a thread some time back that showed the wire harness for the radio. I'm getting some bad alternator whine (only when the battery is low) and want to see if I can ground the radio to another location. I searched, but had no luck.

Thanks.

 

bump.......!

 

What have you used to interface to the factory head and what amplifiers are you using. Did you ground direct to the battery as I had indicated earlier?

 

The radio is the stock bose system. I just want to know the pin out of the radio.

 

I have the head unit out of one right now. I'm busy today (lunch time right now = time to post) but later on I'll see what I can find for you.

 

thanks, mainly, I just need to know what color the power, ground, and ignition wires are.

Thanks

 

looking at back of radio

 

Do you know what color the (r) wire is?

 

Does someone have a working copy of this image?

 

It works, just have to download the attachment instead of simply viewing it.

 

Old images can be opened in a new window instead of viewing them.
Right-click and "open link in new window"

 

That's intuitive, lol. Could really have used that knowledge a lot over the past couple years... couldn't find a sticky about it before my ADD kicked in.

Thanks ya'll.


Adding some substance to this post:

(h) is a, "remote on" for a power antenna I believe (to power it to go up, and goes down when current is lost). [Don't believe a single RX-8 has a mounted antenna, let alone a power one.]
(j) is a, "remote on" for the factory Bose amp, if applicable to your vehicle's VIN. Note: see (1) below.
(n) is steering wheel controls #1 and the only wire you need for any RX-8 as far as I'm aware. (see (p))
(p) is steering wheel controls #2, but these are for call functions (accept call, hang up, issue voice command to infotainment center), so not available on RX-8s (at least S1s).

Notes:
(1) When Bose stereo deck is present the Bose amp is only provided 12v @ 20mA. Many pro-decks have an activation wire; I know Xtrons does for sure -- those activation wires should carry considerably less current, but regardless of the amount of current used anything should work.
