Wideband Lambda wiring
I just got my wideband sensor controller / gauge.
All the diagrams I have show the heater element in the sensor wired to a switched live.
But.
The info in the pack says to wire it to a source live only when the engine is running.
Its not going to be a problem to wire it to the fuel pump relay, just wondered how others have done it, and could water vapor in a cold engine really
damage a hot sensor? the reason given for wiring it to the relay.
ETA its a standard bosch sensor.

That's how I've done it the meggasquirt controls fuel pump relay.
Regarding water/condensation in exhaust damaging the sensor apparently it can, which is why sensors are mounted at the top of the pipe so it drains
from sensor

i not wired, but i will wire to ignition, i not leave ignition without purpose...
dont think will be so much water/wapor in lambda position (pipe), all water gather can / muffler , or lowest point

I am wiring my megasquirt and engine sensors to an IGN switched relay and then my wideband and fuel pump to a megasquirt fuel pump switched relay.
Each output after the relays on its own fuse.
