I have a 99 firebird LS1 with the monsoon stereo. I currently installed a pioneer n2 navigation system and would like to use the stock steerign wheel controls. In the back of the radio there are two wires (Green and Blue) that appear to have been snipped and go to nothing. The steerign wheel controls do not illuminate when the dash is illuminated or when the headlights are on. the only two wires that are not connected to the radio harness are the Green and Blue wire. from previous posts I have found out that the blue wire is for the radio controls on the steering wheel, but i am unsure if the green wire is for the illumination. Can anyone fill me in on what wire is for the steering wheel radio control illumination? Is there list of which wires are for which? Thanks

Correct the blue is the signal wire from the wheel controls and I believe the green is the illumination wire. Check your harness for the corresponding missing wires. Was the harness hacked up for another radio before you bought it as some people cut out the stock harness to connect a new radio and since aftermarket HU's don't work with the wheel controls (unless you have an interface module like the PAC SWI-x) then they leave these unplugged or cut.

The blue is for the control wire. The green I have no clue. I just put a new HU in my car last week and my wheel controls still light up. I left both blue and green unhooked and capped them off. My guess is that either your bulbs in the controls are no good or you blew a fuse in the box. There are two 1amp fuses that are used for steering wheel controls. The one in the bottom of the fuse box provides power and the top in the box provides the lighting. In my car they were black 1 amp fuses.

Just check both of the 1A fuses and they were not tripped. I find it highly unlikely that all of the bulbs wore out on all of the buttons. What are the color wires that come off of the buttons? which color is for illumination?

The steering wheel illumination power is provided on a gray with black wire in the steering column that comes from the fuse panel and doesn't go anywhere near the head unit. The switches send a signal to the head unit through the dark blue wire.

The switch illumination circuit is very simple - power from fuse 13 (STG WHL CNTL) goes up the column, through the clock spring (air bag module coil) to the switch bulbs (two on each side) and then back down the column to ground. It is not impossible for the bulbs to burn out at the same time due to a power surge but I would recheck the fuse. Never trust a visual inspection of a fuse, always use a tester or replace with a known good fuse.

The blue wire in the Pioneer harness has nothing to do with the steering wheel switches - it is the power signal for a power antenna. The steering wheel switch wire is the dark blue wire in the factory harness. It can be connected to the remote jack on the back of the Pioneer HU using an adapter such as the SWI-PS.

The light green wire coming from the Pioneer HU is the parking brake sensor wire - it should be connected to the parking brake switch so that certain functions will work when the car is parked and the parking brake is engaged (video, GPS programming).

i got the same problem, no illumination of the steering wheel controls on my 96 trans am.

Where are the 1A fuses located?????
in the radio or in the both steering wheel controls??

On LS model f-bodies the fuse is in the fuse panel. I don't think LT models have the same fuse.

gregfire

here my fuse cover register, trans am 96 LT1

the illumionation on the st. wheels control and one or two lights for illumination on the volume button are not working, with the stock cd player.
otherwise the radio is working properly.

thanks

Do the controls still function? If they are not lighting up and don't work that is likely due to the clockspring malfunctioning.

gregfire

they work just fine, except the illumination on the steering wheel controls. any help?

Greg

here the wiring from hanes book, no 1A fuses there..
probably there are fuses in the delco radio itself or both bulbs are blown??

there is a 1 amp fuse in that circuit

gregfire

in the drawing? can you tell me where?

your hane's wiring diagram doesn't show it(maybe because its for a LT1) the Mitchell(98-02) diagram shows a 1amp fuse in the #13 slot in the fuse panel on the side of the dash. it protects the grey/black wire running to the steering wheel lights. just like Whitebird00 posted.

The 93-97 models don't have the 1-amp fuse for steering wheel illumination that the 98-02 models do. The steering wheel control illumination is run off fuse #13 - a 5-amp fuse labeled I/P Dimmer that handles all of the instrument panel illumination.

No one has said anything yet, but it could just be your bulbs in the steering wheel controls, they are prone to burn out and to be replaced you have to take them apart and re solder the wires with a new bulb. A search will help you.

gregfire

thanks for the infos
i will check the bulbs.
its not a major thing but it is annoying during night driving
if you have no lights there.
