r33 gts-t ebrake cables are direct bolt on to stock s14 front ebrake cable but that site already got it figured out for you. the gtr r33 ebrake cables are different according to my supplier from japan (thats where i got my ebrake cables)
after you get the ebrake system working on the z32 rear brake upgrade you’ll love the feel of how it locks the rear up during drifting. its an upgrade i relay on it quite a bit for drifting and glad i did it right the first time
good luck w/ the swap
