Just bought a set of US spec ellipsoids, and am gathering information for the install on an 87 eta. I get that you have 3 wires on the low, and two on the high. My question however, is how was the car wired from BMW for a factory US install.
1) Were the highs on without the lows (as the two wire system should dictate)?
or
2) did they mess with the relays (again from the factory) to retain four bulb output for the highs?
According to the ETM for the 89 models (should have ellipsoids) the first is correct, and the lows should NOT be on during high beam operation. Can anyone (preferably with factory install) confirm that this is indeed correct.
