Can anyone take pics or show me a simplified diagram for the stereo wiring on an R1? I have the factory service manual, but I can't understand the letter abbr.

I'm trying to install my Kenwood headunit using a wiring harness I received from Crutchfield, but it won't work. I thought it was a bad headunit, so I exchanged it for another. Same problem exists, so I think the Crutchfield harness is not wired correctly.

I've installed 2 different head units on my base model, but without a wiring harness and they worked fine.

Took it to Circuit City and they said I have a blown fuse somewhere so the red wire isn't getting any power.

Check 3 wires,LR (blue-red) hot all the time
LB (light blue) ignition on
B (black) groung

I checked the fuses in the fuse box 1) next to the dead pedal 2) next to the battery terminal 3) next to driver side shock tower. Are there any other fuse boxes? I can't find a blown fuse.

My DIMMER switch next to the stereo lights up, but toggling it does not dim the counsel lights. I hate electrical problems. *sigh*

Make sure your crutchfield adapter (male I think) doesnt have any bent pins, and make SURE all the connections are good.... It took me 3 tries to get mine hooked up right.

Same prob as ur having... I was like WTF?? why am I not getting power....Wasnt till i busted out a multi-meter I figured out what was up..

Try hooking a multimeter (voltmeter) up to your 12v power lead on the stock wiring harness that ur pluggin the Crutchfield into...If you dont get power there, then you got other problems.

just my 2 cents..

BTW here is the wiring diagram

Non-Bose Stereo wiring mapping
The results of tracing the standard Clarion radio are shown below.
Note that it may not apply to the Bose system which outputs preamp levels and has powered amplifiers in the speakers. There are two main connectors to the Clarion radio which may be similar to those on the Bose. For instance, there is a power supply to the speaker connectors in the doors which is not used in the Clarion setup but would need to be used to power the amps in the Bose speakers. If you are replacing the Bose setup, you will probably need to get a stereo with pre-amp outputs. In my setup there are 10 wires to one of the main connectors and 5 to the other.
Wires I traced are as follows. (Note that some of the wire colours are subject to fading!)
Note: some wires have pink, (possibly silver) rings on them as well as the colours listed below, but these may be worn off the wires.
Note: where two colours are listed, that the major colour is listed first.
Final note: this list is from an Efini RX7, similar to an R1, but it is right hand drive.
10-wire connector:
==============
Red: Front Right door speaker
White: Front Right door speaker
Blue: Front Left door speaker
Green: Front Left door speaker
Grey/Black stripe: Could not trace - maybe front dash tweeter crossover
Red/Green: Instrument dimmer illumination connector
Green/Red: Aerial (Antenna) power lift feed
Black/Red: Could not trace - maybe front dash tweeter crossover
Blue/Red: 12v permanent supply
Blue/Black: 12v switched supply
5-wire connector:
=============
Yellow/Green: Rear Left speaker
Yellow/Blue: Rear Left speaker
White/Blue: Rear right speaker
Blue/Yellow: Rear right speaker
Beige (light brown): Could not trace
Spade connector:
=============
Black: Negative Earth
Antenna connections for diversity system
==============================
Large socket: Main retractable aerial mast
Small socket: Rear window built-in aerial
