Why don’t you connect it (relay pin 86) to the same 12v source you are using for pin 30?
Are you turning the relay on with a switch grounding pin 85? If so, the way described above is best.

Im connecting a wide band gauge
but this gauge send energy to heat the o2 sensor,
this gauges are sensible to volt variation
then want to connect directly to battery
but I need to find a source of switch signal
can be on engine bay or inside car
thanks in advance
