March 12, 2017 UPDATE:
Ok, yesterday we wired his 2013 LEAF SV w/Halogen headlights (no QC) using an add-a-fuse/add-a-circuit from the ebay:http://www.ebay.com/itm/201551151323
These were surprisingly well made, with 15 amp fuses to boot!
Installed the fuse in the box between battery & firewall in #72. We checked this #72 ACC circuit using a voltmeter before wiring. NO PROBLEM - no current with LEAF off & 12V with LEAF on. This was exactly what we were hoping for (but read on, as that's not the end of the story).
Wired up something similar to these TWO-WIRE ONLY 6-LED strips (wires are really tiny gauge, around 20-22 awg):http://www.ebay.com/itm/121670119844
And don't forget this 3M double-sided tape for mounting the bracket (you might not even need to use self-tapping screws to hold the light metal brackets in place because the LEDs are so light):http://www.ebay.com/itm/252570225128SAME EXACT PROBLEM AS THIS THREAD'S OP
LED DRLs work great and look great when LEAFs "ignition" or "accessory" power is on, BUT when J1772 nozzle is inserted into LEAF for L1 or L2, THE DRLs ILLUMINATE and the charger doesn't even need to be powered
--just plugging it into the LEAF activates the DRL from Fuse #72!! However, when the LEAF is fully charged, the DRLs do go off, but if you remove the charger & reinsert it into the nose, the DRLs come back on again and stay on until the blue charging lights on the dash go out.
So, we guess it's back to the PDM a wire #57 (which my tech has wired many LEAF LEDs to in the past with no "charging activation" problems)... BUT, we would still like to use an add-a-circuit on wire #57, INSTEAD OF SPLICING THE WIRE SO WE CAN HAVE A DEDICATED FUSE, AND ESPECIALLY, NOT MESS WITH THE HARNESS.
DOES ANYONE KNOW WHICH FUSE IN THE PDM WOULD TAP #57 for an add-a-circuit??
