I seem to recall a listing of all of the pin outs for the EBL P4 as well as the 7730 ECM. I would like to know what all of the un used pins can be used for or what they read in volts or send a ground signal output. I was getting ready to finally hook up my WB O2 and could not find which pin I need to connect the output to on the EBL so I can use it. I finally found it by doing a search on here but it would be so much easier if there was a listing or chart. Maybe there is and I have just not found it. If there is a listing can someone please point me to it.
Thanks

 

Here is the link to the wiring for the '730 and P4....

My WB is tapped to B2 on the P4 ADC Channel 0
My "G" Meter is Tapped into E1 & E2 ADC Channels 3 & 4 for the Y and X axis readings using Analog Devices ADXL203EB for the sensor mounted in a small case between the shifter and the parking brake handle so it's pretty much centered in the car. has a +- 1.7 G range

 

On top of what daferris posted there is this:

Note that the standard EBL P4 wiring is the same as the '90 - '92 f-body TPI cars. Although with added benefits which are shown in the drawings page.

Thanks guys for the info. I researched the WB O2 and will be using the ADC channels to connect to my Inovate WB controller. I had read about the ADC channels some time ago but had forgotten that that is what they can be used for. The reason I asked about the unused pins on the ECM is some reading I have done on the WB hookup show using pin F14 to connect the WB O2. Can this be done with the EBL also or is the ADC the correct way? Also if I set up the VE learns to use the WB will the narrow band still control the fueling in normal operation and the WB will be just for monitoring? Sorry for all of the questions but this is all new territory for me. I am a real greenhorn when it comes to tuning an ecm.
Thanks.

 

Using pin F14 is for modified $8D code. For the EBL need to connect to the ADC terminal strip inside of the ECM. The ADC web page shows various ideas and methods to access the terminal strip.

To do VE Learns via the WB need to force open loop. Do this by setting the closed loop enable CTS temperature high.
