Carfully remove the retainer:

You push aside the latching tab with either the removal tool or a very small flat blade screwdriver, like this:

Observe the catch tab. It is supposed to be straight, with a slight bend toward the right (as you view it) from it's base. It isn't a contact (except for probing and testing), it's just a "catch" tab!

Don't over-do it, all that is necessary, is to hold each wire in their cavity while you work with the others.

When you have moved/placed them all, re check the positions carefully in good lighting. Some colors are close. Install the retainer, re check if you want.

Here's a couple of tips, posted in another topic by member: gburnsky..

-----------------------------

Here's a couple of things that may be of help.

Tip # 1208746 

Removing the connecting pins from 24 pin connectors.

Forget the pin extractors, screwdrivers, paper clips and all the other gadgets used to remove the connecting pins from the 24 pin connectors, the tool is already included with the 24 pin connector.

The blue pin retainer on the 24 pin connector (the part that looks kinda like a blue comb) works great for inserting into the connector and releasing the pin connectors, just turn it perpendicular to the connector and insert the first "tooth" of the "comb" into the release hole and the pin connector will almost fall out.  Seems like it was made for this.

Just wish I would have known when I started, not on the last two pin connectors I removed.



------------------

Tip # 1208747

Removing the plastic to install the in-dash CD changer.

If you have a gun type soldering iron laying around, flatten the standard soldering tip with a hammer to make a blade (they also make special tips for cutting plastic) and use it to melt/cut the plastic.  No dust or plastic pieces flying around, OK a little smoke but not bad.

Here are some audio system differences in the 03~06 truck models.

Most all of the GM trucks use the Basic or Premium system; the luxury model trucks use of course the Bose luxury audio.

In a Basic system, there is no external amp; the HU connects directly to the speakers and there is no SubWoofer.

--------------

In the Bose Premium System, The amp is just an amp - no smarts but to amplify and provide some woofer crossover. The audio controls and eq are in the HU. Chimes are also generated in the head unit. The radio and aux audio levels vary with the volume control. The chimes, OnStar and Nav audio are set separately and switched/mixed in the common audio to the amp, where no further adjustment is needed.

Automatic volume is set by the VSS signal (the one encoded onto class II bus - low priority).
This is the "Speed Compensated Volume" you have in the Bose Premium System.

A separate rear channel output pair is routed through the RSA and then to the amp for the rear audio.

This system and the basic system makes it much easier to replace or (basic system, add) an aftermarket amp.

--------------

In the Bose Luxury System the audio from the head unit is of a flat line level, unprocessed and not volume-controlled format. The HU only switches in the selected mode, OnStar, Nav, which external audio in, and such.

The luxury system amplifier is a high-quality "smart" class II data controlled amp. It receives the volume control & eq - etc. audio settings information from the head unit via the class II bus to set the particular EQ, volume & such which are all processed in the amp. The chimes are generated in the Bose Luxury System amp also.

The automatic volume control is by the Bose AudioPilot system. This uses a sampling mic for ambient noise pickup. The link describes the rest better. It is noise compensated, not speed compensated.

The output quality is far superior to the premium amp. Much less THD and crossover distortion and a bit more power. BUT, the same speaker set and passive crossovers in the pillar tweeters as the premium system uses, are still some of the Bose limitations. The Woofer output is clean, but still Bose controlled. It can be boosted/amplified, but I doubt one could alter the low pass for a lower frequency capability. Unless it's within the adjustment parameters of some setup software.)

This system is quite difficult to replace the amp with an aftermarket unit. The entire audio system is removed instead. Or otherwise the amplifier is retained and used, as it's needed to process the audio.
