Tree wiring with different connectors

[ManagerBen]

I'm helping a friend who runs drag races using one of your timing systems. Last week one of the drivers hit the LED tree and damaged the left side. We took the tree apart and straightened the metals out but the circuit board with the yellows and the circuit board with the red and greens needed replacing. He ordered new parts and noticed the yellows have a different connector. He received an adapter cable to replace the mating connector on the interconnect cable.

Can you tell me what wire goes where so we don't damage the new boards?

The LED panels connect from the middle board (yellow LEDs) to the tree electronics in the bottom of the tree. The connectors were updated several years back when the part went obsolete and no longer manufactured. The adapter cable is usually a matching connector at the yellow LED end and bare wires. See the photo below for the differences and pin numbers.

Connector Comparison & Pins

Note where Pin #1 is on both the current and new connectors. Cut the wire connected to pin #1 o your old cable. Solder this wire to the pin #1 wire on the new connector or use a crimp to join the two wires. Proceed to Pin #2 and do the same surgery. Once all 5 pins have been connected, the connector will plug into the new board and ready for a power up test. Once all is verified to work properly, reassemble the tree.

Hope this helps.

It was simple enough to cut the old connector off and attach each wire to the new connector. I see why you stated one wire at a time. It would be easy to get one of them swapped around if we cut all of them at once.

Surgery is completed and the tree is back working fine with slightly dented metal skins. Thank you for the directions.
