Just got the BEP 3.0 and an ebay speedo to hook up to a 1991 k75 with a 1987 wiring harness. The speedo calls for a constant power, and a switch power, and obviously the ground. Without the key in the ignition, I can plug my speedo wires into where they need to go and it stays on. This will cause issues down the road and drain my battery. Am I installing the BEP wrong? Seems pretty straight forward. Could I have a wiring issue? This is my first K - bike / motorcycle project, so I'm still learning a lot about the bike as I go. Any help would be much appreciated, thanks!
