aem wideband white wire

[but]

i am installing my AEM wideband and where do i tap the white wire to? (0-5v) I am going to be logging with dsmlink

You would tap into pin #4 on the ecu white wire 0-5v power supply for 02 sensor

You don't wanna use #4. Otherwise your ECU will receive no o2 feedback and cause all sorts of problems. Find a 0-5v sensor that is unimportant and tap into that. Then select that sensor in DSMLink and it will display your A/F ratio.

Thanks man i appreciate your help! So the purple wire i just leave not connected right? so i could tap the white wire into my stock o2 sensor input?

I dont think you can do that, as the stock o2 sensor reads 0-1volt the wideband ranges from 0-5 volts.

1G ECU Pinouts

If I remember correctly a lot of guys use the Pin 15, which was origionally used for the EGR temp sensor on California emissions vehicles (and all 94's according to vfaq)

thanks guys i will look what color wire pin 15 are tonight and solder the white wire in. Just for clarification the purple is not needed? you guys are way smart!

It has been so long since i wired up my AEM wideband i honestly dont remember the colors ... If memory serves (which it probably doesnt) they were red black blue and white. my blue and white wires are currently not connected to anything.... until my ecmlink setup arrives.
