I was going through my electricals tidying things around the batter box on my 2010 FE390 when I ran into a 2-conductor connector that is called "X51 Resistor", "A7" in the manual circuit descriptions. It has a white w/blue stripe wire & a black/blue wire leading to it. The other side of the connector terminates in a shrink wrapped fob of some sort. I can see from wiring diagram in the factory manual it connects to the ECU. I have not measured the resistance.
My question is (after doing a few Google searches and finding nothing!) what does this do?
At this point, I do not have a map switch of any kind. Is this a mapping resistor? If so, and I unplug it what map will it access? Which map when it is plugged in (as it is now)?
Is there a jumper behind the headlight are that can be unplugged for a crude map selection?
Cheers & thanks in advance :drinking:
