Wiring Connections

There are two areas of an Embedded Lockers (EBL) system connections: the typical ECM to engine inputs/outputs and the EBL board connections.


ECM to Engine Inputs and Outputs:

In general unless listed here the ECM wiring is the same as original. This includes power and ground, most sensor inputs (IAT, CTS, MAP, TPS, P/N, VSS, Knock, VATS, High Gear, A/C Request, O2, etc.), IAC, etc. The majority of changes are with the ECM outputs. Many of the outputs have been changed.


Newly defined inputs:

Newly defined outputs:
Note:  if replacing the 16136965 ECM the A/C is a little different. The ECM harness pin C2 needs to be moved to location A2. And the A/CHi bit in Option Word 3 needs to be set. This is required for the A/C to operate. The '6965 ECM is commonly used in the b-body cars such as the Caprice Wagon and Olds Custom Cruiser.

General information on using the ECM outputs:

These outputs are from the common quad driver (QD). In this case they pull low, to ground. There is an option word that will make them active high or active low. IOW, the PE mode when active can be having the driver pull low, or have it open.

As for devices on these outputs, it depends upon the load. Items such as the A/C compressor and an electric fan will need to use a relay. I tend to gravitate towards GM parts. They are readily available and are designed to be driven from a quad driver.

The shift light will depend upon what is being used. If a bright LED, it can be driven directly from the QD.

The PE mode active will also depend upon what it is being used for. If in doubt use a relay or MOSFET.

The relays that GM has been using for fuel pumps, A/C, and fans have been the same one (for the 3rd gen years at least). They have a 60 ohm coil and pull 240 mA (@ 14.4 V).


CCP and Shift Light support:

To use the CCP solenoid support function (note that not all CCP systems use a solenoid), it must be on ECM pin A3. This over rides the use of the shift light on that pin.

If a shift light is still desired it can be moved to a different output. This is done via the shift light output selection in the BIN, see the EBL_Calibration document for more information.  Here are the available shift light output options:

Value to Use ECM Pin Use for Shift Light (normal output overridden)
0 A3 shift light (same as CCP output)
2 C2 FAN
4 C1 PE Active
6 A2 A/C
8 A7 TCC
10 A3 shift light (same as CCP output)
12 A3 shift light (same as CCP output)
14 A3 shift light (same as CCP output)


N2O and EGR support:

To use the standard EGR support the N2O can not be used. This is because they share the same ECM output. To choose which function is desired see Option Word 4, EGR. When that bit is set the N2O functionality is disabled, and the EGR functionality is enabled.

To use the N2O functionality clear, or uncheck the EGR bit in Option Word 4.


EGR & CCP solenoid NC/NO explanation:

The EGR and CCP solenoids on various vehicles can be normally open (NO) or normally closed (NC). The EBL BIN has options to select which solenoid is in use. A NC solenoid will not pass vacuum unless it is energized. An NO solenoid is the opposite, it will allow vacuum to pass through when not energized. When energized the vacuum is then prevented from passing through. Setting the proper NC/NO option is important to have the system work as designed.


High Idle Support:

When the ECM pin B9 is grounded via a user operated switch or relay, the ECM commands the desired idle RPM from the 'IAC - B9in Idle Speed' calibration parameter. An open input (no connection) uses the normal idle speed tables. This separate idle speed can be used on vehicles that run on-board air compressor or welding setups. The upper idle speed is limited by the maximum allowed IAC steps and an upper calibration limit of 3,187 RPM

On vehicles equip'd with automatic transmissions, along with the TCC option bit set, the transmission selector needs to be in the park or neutral position. Otherwise the idle RPM will not be changed from the normal value. This is a safety feature and is only as dependable as the park/neutral switch input to the ECM.

Those highlighted in yellow are no longer used as GM intended. They are used for new EBL functionality.
Wire harness colors may vary from what is listed here.


Embedded Lockers (EBL) Connections:

The connections to the EBL board are all found at the front edge. The RJ11 jack is the RS-232 signal for data logging. Plug the provided RJ11 cord (looks like a phone cord) into the RJ11 jack. Plug the other end into the provided RJ11 to DB9 connector, and plug the DB9 into a laptop serial port. The DB9 may also be plugged into a serial to USB adaptor.

The 12 position terminal strip is for the analog to digital (ADC) inputs, several grounds for sensor inputs, and a 5V serial output.


Analog to Digital (ADC) Inputs:

There are eight ADC channels available for the user. Any device with a 0 to 5 volt output can be connected. The data from the ADC channels is transmitted within the data stream. This allows connected devices to the datalogged along with the ECM data. The channel numbers start on the right with 0. Designations are labeled on the EBL board.

The three inputs labeled GND are for ADC connected devices. They are for providing a ground refernce to the device. Do not connect power leads to these inputs.

The far left terminal labeled S is the 5V serial output. The data stream is the same information as the RS-232 output. The only difference is the voltage level (RS-232 being ca. +-8 volts). The 5V serial stream can be used with some serial to USB adaptors. Be careful here as most serial to USB adaptors are to be connected to the RS-232 RJ11 serial output.


Calibration Parameters to Set for First Time:

There are two BIN's provided on the CD: EBL_F_TB.BIN & EBL_F_PT.BIN

The only difference in the TBI and Port BINs is the calibration area. The BIN with the _TB in the name is for a TBI setup. The other BIN with the _PT in the name is for a port injection setup. 


The TBI BIN is from an 1985 Camaro LG4 engine with a 350 TBI unit and intake manifold. The transmission is a TH350. The TCC lockup tables are from a 350 Camaro with slight mods. Unless your engine/transmission is the same there are changes that will need to be made to the bin. If you have a current bin use that for setting these and other calibration values.

Here is a list of parameters that should be set. The titles are directly from the ECU file, and are further explained in the EBL_Calibration document.



Once these values are checked/set, start the engine and see how it runs. Go slow, allow time for the engine to get up to temperature, data log with the What'sUp Display, and take a short ride. Start with doing a VE Learn from the data log. Flash the new BIN and take another short ride. As the engine starts running better from the VE Learn, you can start taking longer drives and working on areas such as AE and spark advance.

Ease into some WOT areas. From the data log check that the injector duty cycle is OK. Check for excess knock counts and lean operation. Adjust the calibration as required. If you are new to EFI tuning take your time. As you work with the tune it will become easier.
