Hey guys I just made a relay panel for my car. The main purpose is to supply power to my fuel pump, wideband gauge and fans. I will be running everything to a switch so I will need three relays that will need to have a trigger wire(ign.12v) My question is can I use one wire as a trigger for all three relays? In example the red wire going to the radio is ign 12v, can I tap into that 1 wire to trigger all three relays?
