as the title says, i swapped in a JDM B16a, into my 91 civic sedan and for some reason my a/c fan spins with my engine rpm.. i will admit its fun as hell, but my girlfriend doesnt feel the same. any ideas??
you definitely need to check your wiring. The interior fan is directly powered by, and wired to, the environmental controls. Did you splice the fan's ground to your tach wire or something?
