Like the title says i want to do this, ive been reading the ETM's and it doesnt seem that difficult. I have a cluster from an 88 325is that is already in the car. All i need to do is connect the green wire pin 8(E34) from the X20 to the cluster... but where?!? The E30 ETM shows its a brown/blk wire, but leaves out the pin/connector that is goes through.
here is the E30 diagram:
and the E34 one:
