goofy interior light behavior

[junglegreen]

Radio mystery solved. Pioneer and Metra are not on the same page with colors. I hooked red to red from the Metra Connector to Pioneer radio which was not correct.

On the Pioneer side red is switched 12V and yellow is 12V. I switched Pioneer red / yellow wire pins in the Metra connector and all is well with the radio now.

Onto the central locking issue. I need to find the time to pull the locking mechanism out of the door and see if there is anything obvious.

I replaced the left side door lock mechanism with the URO part (thanks Pelican) and now there are no faults in the Alarm system per the Autel scan tool. I have only turned the key ON and have not gone for a drive or put the top up since the lock install.

The lights still behave the same way. When I open the door the interior lights do not turn on unless the key is turned. Also, the radio turns off if I remove the key (doors closed).

Any thoughts on what else could be causing the interior light issue?
