Oddly enough that makes sense. This morning I checked RY and YR wires on C257, C113 and C120. No power from any ofthem.
I was thinking of doing it the old fashioned way with a relay direct to the switch. Of course, easy to leave the lights on that way!
How hard is the power-board? Does it involve soldering?!
No soldering to swap a board over. It is quicker to swap the logic board from low line into a high-line casing, as then you don't have to mess about with the power studs. and fuse box.
Basic process is, once BECM is out: remove screws from the top casing,
Unplug 4x ribbon cables that link to the logic board,
Carefully lift power board up to about 90 degrees (there is enough slack on the wiring)
Undo 7 screws holding the logic board in place
Remove logic board
Do the same for the donor high-line BECM, and then refit your logic board to the high-line case.
Install the 7 screws to hold logic board in,
Carefully lower the power board back in,
Reconnect ribbon cables,
Refit Lid,
Refit to vehicle.
Or you can do as Wammers suggests and just get/make up the external wiring loom (basically exactly the same as the other one you made for the parking sensors) and use a relay to drive the fogs directly from a battery feed. You won't get error warning on them and need a latching switch to fit the front fog face on - but it will work aswell if you don't fancy pulling the BECM apart.
Sadly, no - Touring around China with a theatre show for 9 weeks... been awhile since I was out there, and this is a LOT bigger show too, so will be an interesting experience... I should still have time to have somewhat of an online presence, but having to stop all of my other P38 bits that I do at home whilst I'm away
Not sure, but I can bring it next time I am.
Then your options are hack the wiring and power them direct, not have fog lamps, or buy a HiLine BECM and get Rick the Pick to clone yours and reprogram the new one! BECMs are cheap enough on eBay (mine was £1.50), but I don't know how much RtP might charge....
No need for cloning anything - the logic board from a low-line BECM will work on a high line power board. The only difference that I've seen between high/low line is some of the components missing on the power board. To be fair, it is probably possibly to add in the extra MOSFETs and I'd say a couple of other components on the switch input side to modify the low-line power board, but that would involve soldering! and it's a lot easier to either do the wiring externally or swap the boards over to 'make' a high-line BECM
