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
