as a supplement to my other post, for those of you that used that 951 fan switch (same as shark blade from DR), how did you end up wiring it for dual fans? from what i can tell, one contact goes to stock AUX fan, one to second fan relay, and the other to the main fan. is that correct?
(stole this pic from another post)

 

from what i can find. pin 1, relay trigger for main fan, pin2 for aux fan relay trigger
