How in detail do i hook up the Aem Wideband To my s300 soo the s300 will read off of my wideband oxgen sensor soo in closed loop will make changes based open the wide band ?? if someone has DETAILED instruction PLEASE let me no ASAP! Thanks

you have to leave the stock o2 in. aem only has wide band not narrowband like the stock o2

run the power to a 12v source. ground the black wire
dont use the blue its only for aem system
run the white wire to d-10
if you have a p28. i would advise you to cut resistor 136 & r138

then set up the wideband in s300 to read it properly.

soo this will set it up soo that in closed loop the ECU will adjust its self by the Aem wide band ?? cuz thats my goal here Thanks 4 the help

No, you can't do that with the AEM UEGO. It is wideband ONLY. The ECU needs a narrowband O2 sensor to adjust AFR. Therefore, you need to keep the stock O2 sensor and weld in a second bung for the AEM sensor and use it along with the stock sensor.

I would recommend not useing the AEM and just use the PLX like we suggest. It has both outputs and is very easy to use.
