Aem and ECS on a25

[Clos145]

Hello

This weekend I am planing on hooking up my ethanol content sensor to my s300 v3 the problem is the a25 switch power is being occupied by my aem wideband sensor/ gauge.

Is it okay to run both on the a25 switch 12v or should I get it elsewhere and if so what is another option?

Thanks!

You should use a switched power source from the under-dash fuse box that does not lose power when cranking. There should be empty slots that can be used for this with a spade connector.
