yes that sounds quite possible, especially if it's an ex track car, there is another thread on here where someone has disabled the ABS and had a diagram of the wiring he used so the lights still work, I will locate it for you. There are also relay(s) and a 30A fuse behind the passenger dash (Certainly on the post June 1989 cars, can't say for earlier models)

Btw the bluecossie website host is a member on here (Cozmeiser)
