Ran into one problem but corrected my own mistake:
I was using the wrong wire for ground. The wire coming from the actual foglight switch is the correct one instead of the wire going to the dashboard.
Orange wire worked but I needed to push it more to my 'quick-splice' since my 'quick-splice' size was 16-14 and the orange wire is 18.
NOW....
When you turn on the switch on top of the steering column, parking lights, flash to pass, highbeam...the foglights stays on. Foglight can still be turned off independently thru the master switch.
I think the author of the foglight mod in scoobymods needs to change the diagram. It seems like there should be a Y-wire, which was never mentioned in "tools/things needed" and confuses n00bs like myself.
