There's a top black wire... and side/center black wire... not sure which does what, but at least one of them activates the dash brake light. The car is actually a '72 model (cloned into a T/A a long time ago... by me)

Here is the link to Dr Diff's site that he suggests to get his drum-drum prop valve (that can be used for disc-disc setups).
