Yes, the connectors inside the tree have changed due to the previous connector being discontinued by the manufacturer. The new connector is more reliable connector with stronger locking mechanism making better contact in heavy vibration situations. We have a supply of the previous connector to service existing customer with the previous version of tree electronics.
The photo below illustrates the difference between the two versions of tree electronics. If you need to service the tree electronics, you will need to identify which connector your tree has installed. RaceAmerica is able to service both versions and offer replacements with either connector.
