electrical/fuel cut-off system
 

i jus bought an fc3s...and the guy said that it had a fuel cut off system on it...when i was on the freeway...the fuse for it blew...found out that my a/c blower switch was connected to it(blower on center console does not work)...and when i turned the blower on...thats when when the fuse blew...i jus wanted to know how important the fuse is...because right now i connected the switches directly to the power source with out a fuse...and its running fine...anyone know??

btw...my car is canadian gx 88
