Hey lads finally got my xe loom.

with the the use of this diagram ive got most plug & wires labelled



http://img.photobucket.com/albums/v14/lashednova/XEWIRING.jpg

ALL WIRES/PLUGS ARE BLACK UNLESS STATED OTHERWISE

WIRES FROM THE DIAGRAM:

1- This is the wire which goes to the fuel pump, the fuel pump live. It is blue with a red trace, as illustrated.

2- This is the Fuel Pump Relay, they have a few wire going into them and only one coming out which is item 1 on the diagram

3- This is the big plug which goes into the ECU, It has a silver clip which you push down to secure the plug into the ECU, these can be tricky to master the first few times you do them!

4- These are the dash signal plugs, out of these two you will use the following wires:

BLUE- Temperature Display for Dash, to BLUE on Nova dials
BROWN with BLUE trace- ECU warning light, colour for colour on injection Nova dials/Digidash, unless it was a carb model, in which case, use the choke light as a ECU light, which is BROWN with YELLOW trace
GREEN- Tachometer (rev counter) goes to GREEN on nova dials



5- This is the gromet bung which is where the wires will go trhough to the inside of the car through a 60mm hole you drill in the bulkhead. TIP: you need to cut the tape holding the bung in place and slide it down towards the ECU plug for a better fitment

6- This is the Permanent live for the ECU, it is a red wire, in a black sheafing, it should have a ring terminal on the end, it goes to the positive side of the battery

7- this is the three pin plug for the Lambda Sensor, the line going through indicates that the plug should be around here somewhere.

8- This is the plug for the Air Flow Meter (Commonly known as AFM) Think it has 7 pins?

9- This is the coolant temperature wire, it is blue and simply pushes onto the nipple next to the Coolant Temperature Switch.

10- This is a blue plug with 2 pins, it goes to the coolant temperature switch sensor (commonly known as CTS Sensor). This is located at the front of the block by the top rad hose

11- This is the Crank Position Sensor,, it goes in the lower front face of the block, it is held in by one bolt. The line further up the loom towards the ECU indicates a plug for it

12- This Plug goes into the Hall Sensor on top of the distributor, it has 3 pins, you really cant miss this one!

13- This plug goes into the coil.

14- This is the switched live (a.k.a. Ignition Live). This should go to a 12V igtion live source, this will turn the ECU on and off with the ignition.

15- This is a 5 pin (I think?) plug which connects to the back of the block loom. It will be down by the speedo cable drive somewhere. (The loom from the back of the block should include, knock sensor, ICV etc)

16- These are earth, 3 separate wires, one on cambelt end, 2 on gearbox side, they should be earthed to the fuel rail.

17- This is the plug for the Fuel Tank Vent Valve, it is a 2 pin plug. It goes at the very end of the block, usually bolted to the bottom stud of the inlet manifold (gearbox end)

18- This is a plug for the Throttle Position Sensor (TPS) It is located on the cambelt side of the throttle body.


although the are a few im baffle about so i willl go throught them one by one.

problem 1 wires to and from the ecu plug....what goes to what??
http://i686.photobucket.com/albums/vv229/CIVIC_EG3/MY%20NOVA/problem1-1.jpg

i have listed some of the wires i think i know, although if im wrong plz correct me

PART A- wires coming directly from the ecu plug
green-coil & rev gauge
blue/brown-ecu warning light

brown/white-ecu light???
brown/yellow-ecu light???

black/brown-?
black/blue-?
black/green-?
blue/red-?



PART B- wires coming the bung end of the loom
blue-temp disply for dash
red/blue- relay for the positive of the fuel pump relay



PART C- a wire that is coming from both sides (ecu and bung)and joins in the middle
red/white-?



problem 2 -What does this plug belong to, it doesnt seem to be in the diagram

problem 3 -What is this plug for, as you can see it comes off beside 13- The plug goes into the coil.

problem 4 -according to the diaghram this is 14- This is the switched live (a.k.a. Ignition Live). This should go to a 12V igtion live source, this will turn the ECU on and off with the ignition.
just checkin i got this right

Problem 2 is lambda sensor.

Problem 1,
You only need these mate:

Green - rev counter at clocks
Red/blue - fuel pump
blue - coolant guage at clocks
thick red - batt +
brown/yellow - ecu fault code reader (leave loose)
brown/blue - ecu light to clocks.

Prob 2:

Lambda sensor port connector.

Prob 3:

Rev counter plug snip the end off and fit a connector and bolt to the earth side of the coil.

Problem 4:

Is the ignition live connect to either the igniton live at the barrel or the one near the coil that fed it originally.
