Help with ms3 mini wideband install
installing my Aem wideband sensor in my miata, and im stumped on where to get the sending signal (white wire on the wideband harness). i already tapped into the power and ground in pins 4a and 4b near the ecu connectors.
for the signal wire, ms3 mini documentation says GREEN/RED wire.

Flying miata says LIGHT GREEN/RED. https://www.flyinmiata.com/support/i...gauge_type.pdf
and my friends say BLUE/RED from the front heated o2 sensor harness.
which one do i use???

there is a green/red wire in the connector closest to the map sensor but that one signals the instrument cluster based on the haynes manual.

There are a lot of stories of people not having the correct color wire in a certain position in the wiring harness, especially for the O2 sensor (although that may just be a common wire to be looking for). The instructions from FM for wiring up their VooDoo box even say essentially "connect to the xxxxx color wire at position yyyyy, if you have a different color, connect to the position yyyyy anyway, don't go looking for some other wire of color xxxxx". Maybe there are a lot of color blind people out there, or maybe Mazda just used the wrong color sometimes. My guess is mostly wrong color wires.
