For your convenience....

These are two excerpts from Volume 3 of the 2008 Crossfire Service Manual that you posted on the forum, pointing out that the documentation was different for 2008 convertible top. The "trunk latch retainer switch is still on the 2008 models and the DRBIII process is the same as the 2005 NA and SRT manual.

• The first snapshot describes the DRB III status for the trunk lid.
• The second snapshot shows the location of the trunk latch and the "latch retainer switch"

In the available 2008 volume manual it does not cover what was in the 2005 Service manual.

The next three excerpts are from the 2005 NA and SRT Service Manual I downloaded from the forum. It is just one manual Download - MEGA

• The third snapshot is the removal of the trunk latch. Embedded in the trunk latch is the "latch retainer switch"
• The fourth snapshot is the wiring diagram of the "latch retainer switch" and it's effect on unknown position of the convertible roof
• The fifth snapshot is the same switch showing the grounding of the switch

Then I saw a posting on the forum about the "latch retainer switch" embedded in the trunk latch

• The sixth snapshot is the forum advice about the stuck closed "latch retainer switch"

I disconnected the "latch retainer switch" connector that is connected via the 20 DG/WI wire and the DRBIII still showed the trunk lid was open (Pin 16 grounded). This eliminated the switch itself as the problem. I was still seeing a grounded signal without the switch in the circuit indicating that the 20 DG/WI (pin 16) was grounded somewhere in the loom. I then also disconnected the "Mid" connector between the PTCM and the "latch retainer switch". It appears that the longer loom section is grounded based on the voltmeter readings rather than the trunk lid loom section which was not grounded.

That is when I asked the three questions about diagnosing correctly and routing of the looms in the passenger compartment.
