If the previous method doesnt work, putting the same value(s) across the relay coil will have the same effect, although it may require a whole lot more uf. Again, 16 volts or better for voltage rating. Negative lead to drain, Positive lead to positive 12 volts. FYI, putting + capacitor leads together and - capacitor leads together, causes the uf to add, i. e. 12uf and 22uf = 34uf. John C.
