I connected the heavy yellow wire coming from pole 87 to the yellow wire going back to the headlight relay.

Help!
The blue/white wire should not be on 87, it should be on 86. If 85 (black) is grounded like it is supposed to be, power switched through the headlamp switch in full on position energizes the relay's coil from 86 (blue/white).

Not yellow. Blue/white.

Yes.

Not blue/white. Yellow.

Exactly. Also, if the blue/white is doubled in socket 86, the second blue/white wire went to fuse 14 for rear fog lamp, so in that case there is more than just a relay coil load for the headlight switch contacts; there is also the single rear 21W fog.
