I am sure this has been asked a hundred times but could someone please help me out. i am wiring a hot rod and have an aftermarket wiring harness. (EZ wiring) I am putting 2 relays in the system to control the fuel pump and the electric fan. I am going to run both items off of seperate toggle swithces. Here is my question, how do I wire the first relay to have the fan toggle switch always hot so I can run the fan even with the key off? that way I can use the toggle to cool the car with the key out of the ignition. Second, how do I wire the second relay to the toggle for the fuel pump so that the toggle will only work with the key on? All i need is what sequence ot run wires to what number on my relays I have numbers 85,86,30, 87, 87a. Thank you in advance for all of your help.
