To my knowledge, they are powered 24-7 (with the key on. ) I taped my to the main harness and covered it with heat shrink.



If you find a use for that wire harness, lemme know. I was thinking in terms of an underhood pop corn popper.

i am gonna use the leads to power the relay for a elec fuel pump



as long as they are hot with the switch on it is all good



there is not really a puter (where the motor is concerned) so i think they will always be hot



one thing that concerned me was my batt is at 12. 63v right now



hook the meter up to the heater wires and it is only 11. 99



wonder if possibly voltage dec as temp inc?



doubt it, there would have to be sensors and puter for that



and i dont think it would matter, would it?



how many volts do you need going to one of those bosch relays for it to close the contacts?



thanks

Of all that I replaced and/or installed, I never tested one with variable voltage. Probably 8 volts... ... ... ... ... ????
