Anyone have one?
I am looking for a used overdrive relay for my M46
Anyone have one?
I have a yellow not to sure if that would work?
Is there anything special about this relay besides 3 pins? Can we/ us source a new equivalent? Or is it about a period / colour corect placement?
I ask as I have no clue about the overdrive on the M46 but I am keen to educate myself.
Use a y relay but patch the blue body onto it?
Even hide a suitable relay and keep the failed blue one as show?
Yes you can buy them new.
They are like a standard SPST but pin 85/86 will latch/unlatch the relay from a pulse.
