Remote Control Door Lock Receiver

Run the RPO codes in the glove box to see if it has the bose system. I think on the older ones there is one wire on the stereo connector that needs power when the stereo is powered up for the amp to work if it has one. The stereo should send the power out from that wire into the harness, works the same for vehicles that had the power antenna. some of the aftermarket adapter plugs don't have that wire pinned in the connector. weirdly I found out that even between the 93 and the 95 I have even though the connectors are the same there were a couple of wires in the connector that were pinned reversed. iirc it was the acc and bat wires but I don't remember for sure. you might need to look up diagram for your burb and make sure the adapter plug is pinned correctly. when I installed stereos in my trucks I had ordered the adapters from the jungle site, both showed to fit a wide range of years but GM seems to like to switch things around and use the same plug, that or it's the bastardized 95 model, a one year only for a lot of things!!

if it's like our trailblazer, I found out that in the front doors the speakers are not normal speakers but subwoofers and the little ones (tweaters) carry the normal sounds. the back speakers are normal but still powered by the amp. one of the subs in the front door is blown and rattles. those in the trailblazer are 2 ohm subs which aren't available aftermarket. only way to get one is through the GM dealer or find a working one in the junk yard or gut the entire system and re-wire it for regular speakers!

Oh yeah if your burb has On-Star, you'll also need a module for that too for the speakers to work properly.

One thing I learned about can bus too is when you turn the key to start the engine.... most when you turn to crank it cranks till YOU let go of the key. on a can bus system when you turn to crank and you let go, if the engine hasn't fired up it will continue to crank till it starts or the ECM times out saying it's not gonna start! try that on your 4-runner sometime. just tap the crank and let the key go quick like, see if it continues to crank till it starts!

No On-Star. No CanBus

Center portion of the RPO code sticker is rubbed off, so I do not have all of the RPO codes. If it were Bose, it would be advertised all over the truck.

No not really. our trailblazer has no labels anywhere. I had a hunch it had it along with XM satellite. ran the RPO codes and confirmed it. you can run the vin on some sites online to get the installed options at well or swing by the GM stealership the parts counter can pull the info off the vin too.

No XM satellite. That came into play about 2001. The middle section of my RPO codes have rubbed off the sticker.

On the plug to the Pioneer head unit, I have three wires not used/connected:



Reverse gear input is for a back-up camera, which I do not have installed, nor intend to.

System remote control not used. It came with a remote fob, but I have no intention of using it.

Mute, I assume is for muting stereo when a phone call comes in?

RPO sticker:

 

[Big T]

GM side Metra plug. L to R 6 wires:
Yellow (missing in pic), Orange (missing in pic), Pink, Grey, Violet/White, Black.




Yellow is Hot in ACCY and Run. It is connected to Yellow at the Pioneer (P) harness plug which is power regardless of ignition position.

Orange is hot at all times. It is connected to Red at P plug which is for electric terminal controlled by switch.

Pink is for ? and not connected. Metra plug has a blue wire in that position, both sides and says it’s for a power antenna, which I don’t have. So pink is not connected on the GM body side.

Grey is for ? It is connected to Orange/White at the GM side Metra Plug, but the Pioneer side Metra has an empty pin. Only grey I can find in the manual goes to LF Speaker. Maybe I’ve called the color wrong. Wish the f’n manual would should wire colors and function to their pin position.

Purple/white is show as hot at all times coming from headlight switch/dimmer. Metra plugs, both sides, have an Orange wire in that position. I have it connected to Orange/White at the P plug which is for lighting switch terminal.

Black is ground. It is connect to black through the Metra plugs to black at P plug which is also ground.

The next 4 L to R are speaker wires.

Light green is + for RF speaker; Dark Green is - for RF speaker. Connected to Grey and Grey/Black stripe through Metra plugs to Grey and Grey/Black stripe at P Plug which is for +/- at RF speaker respectively.

Same pattern is repeated for the next two Tan and Dark Grey speaker wires for LF Speaker.

Looking Pioneer instructions, it says the unconnected Blue/White is to be connected to system control terminal of the power amp. As noted this wire has a tag saying it’s for “System Remote Control”. Does this go to the Grey to Orange/White to unpinned at the P side Metra plug? I think this is my mystery. I need a lemonade as I’m tired of this crap.

 

[Big T]

On the bottom of the GM side Metra plug I have a Green and Green/White pair of wires which are not connected. Manual suggests the Dark Green/White is for Transfer case control module with Electric shift. WTF is it doing in a plug for the old stereo? Again a diagram showing wire colors to pin position on the plug and their function would be so much more coherent.

The GM radio gets a signal from the VSSB and as vehicle speed changes the volume is adjusted.

So not needed for this Pioneer head unit.

 

[Big T]

Shown in pic is the back of the transfer case switch which has two plugs. What is the third large unused plug for? I’m putting this POS back together for the day so I can run to the market and do an oil change on it.

 

[dbrannon79]

That blue wire marked system remote is the one that sends power to turn on the amp. I will see if I can find the schematic for your burb, it should show the wire colors as well.

I have the GM manual and have been using it.

 

[Big T]

Front row, 4th wire/pin from the left, tell me what that wire goes to and does. I can’t find it in the shop manual and I can’t really tell the color. Tan? Grey?

 

[dbrannon79]

Look at connector C1 which should be the black connector, look for a pink wire and if you connected anything to it.

 

[dbrannon79]

C1 grey should be the left front speaker (-) there is also a grey wire on C1 for dimming for when you turn on your headlights.

 

[dbrannon79]

I found your RPO code. UQ3.
