I'm going to do this Fan mod to my 1998 Blaser. Does anyone know if I use the #42 pin also or is it a different one?
in my 2000 s10 what i did was repinned the wire that goes to the air pump to the fan 1 pin, 42. ditched the air pump. the air pump already has a relay and a30 amp fuse on the passenger side fender well. remove the battery to get to it. i used that power source, fuse and relay and wired both my fans to it. that relay gets a 12v signal for the air pump. so you hafta make that pink signal wire a constant 12v, i just cut it, and slid it in with the fuse blade. and what was the constant ground you connect your fan 1 ground signal 2. ta daaaaaaa... theres no 2 speeds and no running one fan, but you can control the temp via the pcm, a/c, coolant temp, and even program it to run after its off.
