I need relay help (Ive read all the stickys) I cant figure out where the 85 side of the relay goes. Ive got 30 to battery, 86 to WOT, 87 to solenoids. Does the 85 go to ground or to the fpss?

30 = High current input
87 = closed circuit high current output
87a = open circuit high current output
86 = low current "switch" control (normally ground)
85 = low current "Switch" control (normally 12v)
A relay allows you to control a high current device with a low current circuit. with the low current circuit open (85 & 86), the internal switch completes a circuit between 30 and 87a. When you close the low current circuit (85 & 86) the relay switches to send current out 87 instead of 87a
87 = closed circuit high current output
87a = open circuit high current output
86 = low current "switch" control (normally ground)
85 = low current "Switch" control (normally 12v)
