I have the FSM at work.
It looks like there are 2 wires:
A dark Blue wire from post #23 on the bulkhead goes to the lamp that goes to the field side of the voltage reg.
There is also a black wire that is listed as the dual brake system ground that goes to post 12 on the bulkhead and then to the brake lamp warning switch on the prop valve.
My interpretation is that power is suplied through the ignition system and the black wire provides the ground when the warning switch is thrown.
the same setup is for the standard dash except the standard dash wiring is provided with a larger circular socket thingie. On the FSM the black (ground) wire comes from the B post (7 o'clock position) on the round thingie and the blue (power) wire comes from the A post (6 o'clock position).
I would assume that if you at least get the black brake switch ground wire correct a supply from any accesory power source would make it work.
If you need i can try and make copies of the FSM and post them.
PS. my buddy did the same swap in a 72 satellite last year. Without a doubt a very cool and worthy upgrade! He loves it!

Honestly, you should have ( Like I did ) change the harness too... less time, better sure about and they are available all around in good prices.
some differences between standart and rally cluser/harness:
On standart, gauges just work getting power from one BLUE wire, what is RUN source from ign switch. Is the same wire what does feed the oil light and brake light positive sides.
On rally, the gauges are being feed by ACCESORIES from ign switch, so if you put in RUN and in ACC ign switch you will have reading on both.
Then also Rally harness feeds a ground to the cluster through a spade terminal to voltage limiter. Standart gauge gets the ground on circuit board thorugh the hex screws directly from chassis

I hope to post some pics of this little project soon. All slick and painted, no wood grain.
Well I can't wait to see them... Plz post some soon!
I have two of these cars, a 71 road runner that will go pretty much stock and the car pictured in my sig that I am doing all the modern upgrades to.
I never really cared for the wood grain look in these particular cars and the radio is an abomination, what were they thinking???
I have a few damaged outer bezels for these style instrument clusters that would make perfect test subjects for modification.
I haven't done anything with them yet cuz I haven't made up my mind as to what I'd like to do to them.
So I'd definitely like to see your work.

Don't know if you still need this but here is an area with schematics:
I do have the wiring diagrams but was just not sure of the brake warning lamp socket. I'm sure I know what I need to do now. I'm getting ready to go out to try to find a two wire light socket that will fit the back of the cluster that won't ground to it. Thanks anyway!

Doesn’t have to be.
It appears that there's more than one '72 Road Runner owner that listens to KZOK - Seattle's Classic Rock station...
So I'm curious, now that I've already had my radio modded replace the guts with digital guts and work with a remote CD changer: It appears that I need to have it modded again for a digital display. Where'd you get it done?

That's pretty sweet. If I was keeping a radio in my car I would consider that. My bezel was already cut plus I wanted to cut out the radio area anyway for gauges.
