Quick update, I contorted myself into the driver's foot well of my right hand drive Japanese domestic manufacture 2012 gen 1 Leaf and unplugged the TCU. I can confirm that connecting pin 1 (battery +ve) to pin 11 (EV System Activation Request) causes a beep from the front of the car and a few relay clicks. I didn't try to activate climate control to confirm that it works, I'll try that later this week and if it does, hook it up to the OVMS. Splice into the loom in the cramped conditions under the dashboard won't be fun. I wouldn't be totally surprised if the TCU does the charge timer wakeup, so preserving the existing circuit is a good idea. http://www.mynissanleaf.com/viewtopic.php?p=438109#p438109 says the Gen 2 Leaf doesn't need this circuit, and the same source describes CAN message to do the wakeup. If anyone wants to test that I can add that message to see if it works. Has anyone seen a message on the EV CAN Bus that would distinguish a Gen 1 from a Gen 2?
