MG MGB Technical - 68 MGB Wiring

I am rewiring my 68B and I am not sure were the wire from the panel light switch on the cowl hooks up. Item Nr 31 in the Moss parts book.
Also the wire from brake pressure switch .
Item Nr 30. I have checked all wiring diagrams including Auto Wire with no luck. Thanks Bill

The panel light switch gets a red from a 4-way bullet connector which has two other reds in it - one from the main lighting switch and the other to the map light switch. The other side of the switch should be red/white which goes through a 2-way connector to a 4-way, two other red/whites come out of that and go to the fuel gauge and tach, and a third goes to a 6-way connector for the cigar lighter and the other three gauges.

The brake pressure switch should have a single black/white which goes direct to the failure light and test switch, no connectors that I can see. AFAIK it picks up an earth to light the lamp (when the pressure has failed and the switch has operated) from its physical mounting in the manifold.

Incidentally, a 68 should have two in-line fuses for the front and rear parking lights, with red wires each side of both fuses. I'd be interested to know where those fuses are physically located, I'm guessing it will be where the main and rear harnesses join together in the mas of connectors by the fusebox.
