Re: IC pump trick??
Started doing this mod to my Sy this evening, after finishing up my IC and CAC upgrade (pump and fan). I grounded the yellow wire and no pump/fan??! Took out my multimeter and found that the fusible link that supplies high-current voltage to the relay is blown/bad. So, for the last month, I've been running around with an inop stock CAC pump! ... glad I wasn't driving it much. I'm going on vacation for a few weeks, but will post some pics when I get back. Remember, even if the fuse is good, the fusible link at the battery may be bad.
