Hi I just purchased a Aem wideband gauge there are red-power,black-ground,white-analog output,blue-serial output.now it says white wire connects to an auxiliary unit that accepts a 0-5 volt input,so do I need to use this white and blue wire?its for a Ls1,thanks
What are your trying to hook it too? You don't have to hook the white wire to anything for the gauge to work. If you want to log with something like a HP tuners pro system you hook the white wire into the input of the HPtuners box.
To get the gauge to read all you need is the red connected to a switched 12 volt power source. Black is ground. Connect the plug coming from the included o2 to the other end of the plug that goes to the back of the gauge. You will having a working wideband with that. The white and blue are optional. White for datalogging blue to connect to any other aux unit.
Im wondering, going by the wiring diagram, whether the blue going to #2 pin is feed for the datalogging of the hptuners mpvi2+?? obviously I dont have the ANALOGUE data logger...

You resurrected an 11 year old thread with a question that is only tangentially related. For a proper answer, you need to learn proper search skills and read until your eyes bleed.

So.... You don't know then? Cheers for your pointless input,.and let someone answer that ACTUALLY knows..
blue is serial output for whatever system you want to feed it.
white is 0-5v analog output for the same.
its not complicated....
Thank mate. Yeah I knew the blue was for that but just wanted do double check to splice it in with the yellow pin 2 or disconnect the yellow and replace with the blue from the aem. Just cut it and joined the yellow and blue wire together to the yellow pin 2...

Ok, dumbass, let me explain. Wiring diagrams can change at any time at the whim of the manufacturers. This makes an 11 year old thread an unlikely source to trust for the most up to date info. Also, AEM and HPT both have info available to answer your questions, rather than an 11 year old thread on this forum. Don't blame me for your lack of research skills. I wish you far better luck on your wiring and wrenching endeavors. I don't know how to teach people to do a proper search, so I try to shame, annoy, and berate them into learning how. Maybe that is a character flaw. Could you do a search for me and find out?
