how do you connect the summit rpm switch to the vacum solenoid on to a 3.5 swap 4th gen and on the nismo fpr which way do you turn to lower the fuel and raise the fuel

 

For the RPM switch what I did was connected a positive on the vacuum solenoid. The Summit will send a ground to the switch which will make it open. Use the ground.

I got the tip from one of these electronical engineers here on the .org

 

Screwing clockwise usually increases pressure on fpr's, but the easiest way to check is to turn it either way while watching your pressure gauge.

 

i adjusted the fpr alil better than before know just need tp get a write up on how to install the summit rpm switch
