Well i got it in yesterday and there are two wires that are not connected to anything.. One of them i know is for the wideband o2 output. But the other i can not figure out.

I called dezod but paul said he could not tell without seeing it in person.. Maybe someone else has seen this.


When i look at the aem ems wiring diargram its says primary o2 input.

Here is a pic of the aem side connector of the wire thats connected to nothing. its white and color and i pulled the wire into a little loop so u can tell which one it is
Pin c16



In this picture these are the aem side connectors you can see which plug it is that the wire goes to..





Here is the white wire not connected to anything on the car side of the pnp harness

 

does the aem unit draw all power from the ecu or it needs a supplemental 12v source so get adequate voltage.. im thinking it could be a wire for a 12v source not sure though

 

After getting some time to look into this deal (didn't have time right when you called)

There should be several flying leads on that harness:
(1) Wideband O2 input (C16) This is the 5V analog input for a WB O2
(3) For MAP Sensor (Power, Signal and Ground)
(2) IAC Power & Ground


Sorry, it's not easy for me to TECH something used like that RIGHT on call with demand while in the mix of doing 3 other things. We are technically not supposed to tech support second hand purchases like this, but I try to help out where I can.

 

Totally understand paul. I just knew alot of these were sold and someone else might of know what it was right away.. I understand since i bought it second hand its no longer your problem.

And i do appreciate any assitance you give me or anyone for that matter. You guys are as big as your are for a reason. Thanks

 

Ok so now i understand that c16 is for the wideband o2 sensor..


there is a second white wire disconnected that is C20 which is labled TDC+ Spare Speed Input Is this suppose to be connected some were on the pnp harness?

Could this of been something he added?

Please someone help as i need to get the car running

 

hopefully dezod can release a pinout diagram on this.. or finally aem will release an aem standalone unit for the tc.. that way there will be a better tech support concerning issues like this.

 

Supporting second hand purchases of such an item are not easy. We do not know what the other person did. We tech support all of the new AEM EMS purchases with ease because we know EXACTLY what they are getting and what they need to do.

 

absolute truth.. I imagine different units are modified in different ways depends on the customer needs

 

Yes, 100% correct

 

Is there a PDF or any info on how this model is suppose to be hooked up?

I understand i didint buy it from you guys.. But i just need to know were pin c20 is suppose to be hooked up if it all..

At this point i think i just wanna fix it and sell it for a new dezod standalone that way it custom for me

 

or may you can send it to them and have it figured out or maybe customize it to you application.. they might have to due to you build, but hopefully you'll have a simple fix.. good luck

 

Through e-mail he said for 75.00 He would update it to the current box there using.

But im going to assume he would want the harness pefect to do it..

Plus he's pretty backed up making there standalone box's right now and wouldint be able to do it untill end of next week..

I really just need to get the car started!

 

No luck with the tunes I sent you? Are there anywires not connected on the wiring harness side of the plug (where it plugs into the car harness)?

 

If your box is that old this may not be a bad idea for you. Paul has been really helpful with everything I have asked and more.

 

well i just found out the kid who had it before me had his burn up and sent it back to dezod for replacment.... And i figured out what the extra wire was...


Thanks to every for your help!

 

sorry to hear that how did it burn up? What was the extra wire for?

 

No No,

It burned up when he had it.. it was sent out and replaced..

The extra wire was for a output to some gauge he had that worked with the aem box.. sean church was who wired it up for him..

I will find out his sunday about the map,s as im not with the car untill then!

 

I knew what you meant, I didn't know if you knew how it burned up on him though, was it something he tried with the box and it caused it to burn up?

 

not really sure... I will have to call him and ask... sorry for the long replys im painting a XB1 right now so i come back between coats

 

I know who's box it is then. The com port took a dump and stopped working causing erratic responses to the box. AEM serviced the unit and it worked fine since then
