Here's how I see it:

Yes. I think you're right re: question 1.  P97.66 for an '85, shows a
fan with 2 resistors in series. (front fan?) There's a solid thinner
line from switch position 2 to the second resistor. It seems P 97.82
is missing that thin line. Actually, looking again, I see a bit of the
line shown in the pictoral box containing the resistors.

Check out P. 97.99    :)

Other later MY diagrams also show the motor ground going to the junction box.

The Bentley has mistakes!

> OK questions - 1) Speed #2 Y/BK wire shows it going to nowhere.  It seems that it would have to go to the series resistor (to the mid-point of 2 resistors) - correct?  Why would it not be shown this way?2) The under seat connector has 4 wires - the 3 shown to T4a and a brown. Yet the diagram does not show brown from/to T4a?  3) Brown from heater fan goes to ground #6 in diagram - which is listed as  under the rear seat.  I happened to pull the ECU today and there is a ground, but it appears to be used only by the ECU.  Does this ground run all way up front - perhaps through switch?  I can't imagine the running this wire under the van and around and back in to a single ground behind the ECU instead on a few inches in side the van or having the ground behind the heater instead,
