First start by sliding your passenger seat as far back as possible to allow you the space to operate. In our test vehicle, this 2001 Acura Integra the ECU is found in the lower kickpanel on the passenger side footwell.

After you have the kick panel removed, then undo the 2 10 mm nuts holding the ECU Cover on. Then unbolt your ECU, pivot it toward you and start unplugging harnesses

Remove your Emanage unit and the harness supplied. Lay it all out in front of you so for ease of install. Take the time to review this handy chart which shows you how to connect the Emanage to a MAP or pressure driven vehicle, like your Integra.

First we start with the White Greddy wire, which for our car goes to the MAP input signal. You will be splicing into this signal as you don’t want to rob the ECU of being able to see absolute manifold pressure.

First step of the wiring process behind our How to Install a Greddy Emanage article is the MAP. Find the MAP input signal, wire D3 on our pinout. Cut this wire in half, connect the white wire to the sensor side of the harness.

Then connect the Green Wire on the Greddy Emanage Harness to the other side of the MAP wire. The green wire is MAP output signal.

51

 

Take the brown GReddy Emanage wire for RPM Signal and connect it to A20 on the ECU, which would be Ignition Control Module.

61

 

Take the red Greddy wire for power and connect it to A11 on the ECU, which would be ECU power on this P72 OBDII ECU.

71

 

Then take the black Greddy wire for ground and connect it to A10 on the ECU which is Power Ground 1 Take the Yellow and light blue wires, which are VTEC output / input respectively. Find the A8 wire on the ECU which is the VTEC Solenoid wire and cut it in half. Connect the Yellow wire to the sensor side of the harness, and connect the light blue wire to the ECU side of the harness

81

 

Locate the VTEC Pressure Switch, pin C15 on the ECU pinout. Cut this wire in half and take the Purple VTM output wire on the Greddy loom and connect it to ECU side of wire C15

Now wrap everything up, and mount your Emanage somewhere safe and hidden away. You can opt to tuck it up and behind your glovebox or try to squeeze it behind the passenger side kickpanel.

There are quite a few versions of the Emanage in existence as we talked about at the beginning of our how to install a Greddy Emanage, including the Ultimate.
