S4 NA Auxiliary ports activated by rpm switch
This setup works perfect. Used an S5 ACV, summit racing 830449-1 rpm switch, repurposed the EGR solenoid. I deleted the EGR valve. Picked up tach input from leading coil single wire. Picked 12 volts up by taping the EGR solenoid, picked up ground from the frame. Output from the rpm switch went to the green wire on the EGR solenoid plug. Set switch up for 4 cyl and set dip switches 5 for 1,000 and 8 for 100’s to trigger at 3,800. Ran vacuum line from ACV output to top output of solenoid and back nipple of solenoid to the auxiliary port input. Reply with questions.
