| Pictured are a Wiring Specialties EFI harness and AEM extension harness to be used for an EBC installation. Extension harnesses let you tap in things like EBC, Widebands, Air fuel controllers and etc without touching the EFI harness that does not give a lot of space for wire tapping for multiple devices. 
Pre Note: i strip wires twist and soldier without ever cutting the wire being tapped in half. i de-pin wires from clip and slip heat shrink over tapped wires, re-pin then heat the shrinks.
 Here is where i figured a little way to make an extension harness fit better by doing a 180 with the ECU in the ECU bracket so the ECU bracket can still be used and hold the ECU in the stock location. This is the original orientation:
 New orientation, rotate ECU 180 degrees (do not flip it over, sticker stays facing you):
 Disconnect Evap drain tube from Evap box, run EFI harness up high over the drain tube and reconnect drain tube. Harness will now fall from other side of ECU location:
 Like so:
 Connect like so, always make sure connections are seated all the way across the clips.
The wooden ECU bay cover board will fit over without squashing or putting pressure on the ECU or hanresses. Your welcome ;-)
