Help me identify my LOOM!!!

[thedjse]

I am struggling to get my nova started after fitting a 2.0 8v so i have pulled everything out and starting again

Im uploading pics of all the wires and connections that are in the engine bay from the Nova LOOM:

Any help with this would be really appreciated!!! :)

4th pic

Green/blue is for oil pressure light on dash
Blue is water temp on dash
Black/yellow is to the alternator for the dash light I think? Not sure tho

3rd pic
I think red/black thick one is to trigger the starter motor

[Nova_Tek]

Agree with 4th pic ^

7th pic looks like radiator fan switch wires

[Nova_Tek]

3rd pic looks like alternator wires

[Nova_Tek]

5th pic looks like windscreen washer pump wires

[Cheeze]

Top pic, wiper motor and brake servo warning wires

2nd pic, bulkhead fan, grey/green is for underbonnet light, red battery, black/red ive always found they are unused

3rd red/black starter wire, blue/white battery charge light

4th as above i think,

5th washer bottle motor plug

6th not sure

7th horn wires i think

[Adam]

Blue/White is the alternator "trigger" wire, goes to the dash light.
Black/Yellow is for autochoke 12v, so not needed.
Thick black/red is starter solenoid from ignition switch

1st pic looks like black plug-wiper motor, two other wires brake fluid level switch

Big black plug in 2nd pic looks like heater motor blower

5th pic looks like windscreen washer

6th pic looks like rad fan switch, maybe horn or reverse light too. Cant remember those off top of my head

[Nova_Tek]

1st pic is wiper motor wires and brake fluid cap sensor

*PS sorry for posting individual posts, studying the pics carefully

This is brilliant info thanks guys

Im not bothered about anything other than getting it started atm so all this info is helping discount wires that arent needed for a spark :)

I know it's not really relevant to your pictures but in the future someone may come across this thread asking about a 2.0 8v conversion, so here's the link ;)

Also the wiring is similar to the C20xe.


Wiring Guide-Thanks To Paul

Right, hope I haven't forgotten any wires here, otherwise be pretty useless

This is for a DISTRIBUTOR C20XE, the dispacks are identical apart from they have on more plug for the dipack unit.

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.

Other Wires

You need an earth that goes from the gearbox to the chassis.

You also need to connect the starter motor live to the +ve side of the battery

From the Nova Engine Loom (found by brake fluid reservoir), you also need to connect the black with red trace to same colour on the engine loom at back for the starter motor. Again from the Nova loom, you need the blue with white trace as the remote wire for alternator, to the same colour on the XE loom. Again for the Oil pressure, you need to connect the blue with yellow trace and blue with green trace to the XE Oil Pressure sender, this is found down behind the Oil Filter.

Hope this of some help to some of you,

Paul

6th looks like headlamp wiring?

[thedjse]

Top pic, wiper motor and brake servo warning wires

2nd pic, bulkhead fan, grey/green is for underbonnet light, red battery, black/red ive always found they are unused

3rd red/black starter wire, blue/white battery charge light

4th as above i think,

5th washer bottle motor plug

6th not sure

7th horn wires i think

So you dont think it needs joining to RED/BLACK in pic 3?
