ok im doing a 3800sc from a 97 Riviera to a 87 fiero . when the pcm sends a signal to turn on low fan and hi fan is it a ground or 12 volt pos? also when the pcm sends a signal to turn on hi fan(im using two fans) does it turn off the low fan or is there a signal sent to hi and keeps signal to low fan?
it grounds them. fan run setpoints are adjustable to whatever you want in the PCM. I'm setting one stupid low to run my intercooler pump. Stock, fan 1 kicks on @ 100 C, fan 2 kicks on @ 108 C
