Karl von Salzen on the Type2 list mentioned the same thing. My reply to him
(and the list) contained too much quoted material so the list response
bounced. Anyway, after my initial post I went back to my testing and
discovered that I had continuity from the FI connectors to the resistor pack
plug. However, the Bentley says the terminals for the FI connectors away
from the big black ECU connector are 88e, 88b and 88f, which are identified
on the dual relay as such. Is this a Bentley error, or am I reading things
wrong?
