Default ESC to BEC connection Question

I am new to electrics and can't find this answer posted online. How are you guys attaching the wires from an external BEC to the ESC? I am trying to solder them to the same Deans connector that goes to the battery and having a lot of trouble connecting two wires at the same time to each Deans terminal. It just occured to me that maybe there is trick to doing the connection.
Thanks in advance for any advice!

You have the right idea. However in soldering you ideally should have a good mechanical connection before putting solder to the parts. I typically, when using Dean's[0], will take about 10MM of insulation off the wire from the BEC and wrap it around the power lead to the ESC. Solder that then solder that to the connector.

[0] I no longer use Dean's as the EC3 connectors are much simpler to deal with for me.

Mike,
Thank you for the quick reply. I was sure there must be some special trick to getting these two wires on the same Deans connector. I'll redo the wires per your advice.
Thanks for the guidance.

Here is my mock up for a UBEC installation - as mentioned, twisting the two wires together before trying to attach 'em to the Deans is the answer.

Thank you Doctor. Sending the detailed photo is very kind of you! Now I know exactly how everything hooks up and how to do the leads so that they stay put. I just soldered the BEC to the ESC by twisting the wires before soldering. I then used heat shrink to add additional holding power and for strain relief.
Everything is working perfectly.
Thanks again for taking the hassle out of this gas to electric conversion.

Excellent job! Glad to be of help! Don't forget to disconnect the red wire from the ESC if your ESC has a BEC onboard.
