I put block offs on the front when I go to the track and leave the mirror turn signal connectors unplugged. On the rear, I have the block off which covers the opening for the tail and there's a terminator plug for the tail wiring and a terminator plug for the tail light...I have a dummy tail light and headlight. On the rear turn signals and license plate light, I'm using the Furturismoto unit, so there only one plug which connects to the bike. This is different from the OEM tail which has one plug, but is split in the tail with a plug for the turn signals and license plate light. I wouldn't think the error is tied to the turn signals as that would have to be resistance based. The resistance could be different between the incandescent bulbs (rear turn signals) on the US bikes and the LEDs everywhere else.
