I thought you said the parts I had were different? I have 2 LKMs in the E34s.. me info says they should be compatible.
At the time I was looking for a "mustard relay" which is a different beast. I was unaware that the LKM was needed.
Dad has a couple he brought back from the yards in Germany, BUT they don't run his center brakelight. The USA version that came in the car has some sort of fault in it that makes the RF park/marker lamp inop. We have yet to figure out the fix, or how to rework the euros to activate the third brakelight. So it seems expedient to find another USA model...
