LM317T Voltage Regulator with Pass Transistor

I thought it might be helpful to see how the Relay installs on the TM Series markers. The v1 TM-7 has an Air Transfer Tube that adds some complexity/problems to the install, so you might consider purchasing the latest version when you buy the Relay. The TM-15 is a much easier installation following the included instructions.
