FAQ
How do I know which connector is which on the radio module?
The 8-pin connector is typically positioned at the top, facing towards the
front of the vehicle. Make sure to disengage any locking tabs before
attempting to release the connectors.
Overview
The AP4-GM61 installation is done at the radio module. The radio module is located in various places throughout the different models of vehicles.
Notes:
In some cases, the vehicle’s radio connectors will have a red locking tab that
does not allow for the radio connector to be released until the locking tab is
pulled away from the connector. When the locking tab is pressed almost flush
against the face of the wire side of the connector, it is in a locked
position. When the locking tab is extended away from the face of the wire side
of the connector, it is unlocked, allowing for the connector release tab to
press in fully. See the photo below for an example of how the release tab
looks when the release tab is unlocked.
