Put a switch in series with the supply or return side of the coil of the fuel pump relay. In '88, it was under the driver's seat and the supply side was Red/Blk and the return side was Tan/Lt Green. You don't need a heavy duty switch because you are interrupting the current to the relay coil (about 0.1A).

Do you (or anyone who may be reading this) know where I can find a how-to or ifnormation about installing a fuel cut off switch (that's NHRA Legal) on my 88 GT? I just finished the Battery Kill switch and the external +/- quick chargers along with the blowdown tube and purge. But I'm trying to find something on the fuel line kill switch. ;)

Thanks
