OK ive got a weird one for you I bought a 90 FC and noticed that the powersteering line that goes to the pump has a makeshift T connection connecting another line to it. So i figured it was just an newer pump and the car needed a S4 pump! Turns out that the car doesn't have the wiring connection for the S4 only the S5 so i can't use the alternate pump! So what should i do!! I don't really want to change out the whole steering rack/misc parts just to have the correct setup. Anyone that can help?
