anyone got any ideas need this sorting asap please

[Steve]

Have you got the car running yet? theres loads of spare wires on mine, and if it doesnt affect the running then I wouldnt worry about it.

Im sure someone else will be able to tell you what it does though.

[just vaux trev]

i know it goes somewhere i took it off i remember it having a zip tie on
to hold it in place but i know stupid me..... didn't label/mark it

[Mike]

Looks similiar to the wire that goes to the back of the dizzy on an SR?

[Adam]

Coolant Temperature Sensor plug

[just vaux trev]

/\so it should go where the blue one is in the pic

[db_1.2]

^^^So useful yet you have bad rep?!

(Adam not just vaux trev):)

[Adam]

/\so it should go where the blue one is in the pic

No, looks likes its to an old loom to me.
For the original engine......

[just vaux trev]

i know i took it off it was held on with a zip tie as the clip is missing off the plug doh can't find my haynes either..
grrr it's putting me off finishing the engine now and just ordered more parts :confused:

[Adam]

Just leave it then.
Its to the old engine loom.

[just vaux trev]

/\ sorry should have been more specific it was conected to the engine while it was in the nova i took the engine out to paint the bay/block and do gaskets and now the engine is back in i can't rem where it was from

[Adam]

Check around the top hose/thermostat area.
Sensor should be there.

i can't see nowt around the front by top hose and it wouldn't reach there
how much have i stuffed this one???
1st time this has happened but then it's my 1st 2.0 8v

[just vaux trev]

bttt

[Riggy]

the loom only runs 1 way lol so its got to be quite close to where it is on the loom

[just vaux trev]

still need help!!

[Lee]

are you getting any reading on the temp guage?

[just vaux trev]

tbh i am still waiting for parts to be delivered
to complete engine rebuild so havent tried
ign or crank

[Lee]

There should be a blue wite connected to the thermostat housing, although why its in a massive plug with an earth is an odd one.

[just vaux trev]

i brought the nova with the engine already in and i thin the wiring has been propper bodged i'v never seen wiring like it even the fuel pump wireoff the donar hasn't been used (blue red trace) it's a strange one this
im used to the loom just sitting in place most of the time it's obvious
where they go..
did you know lee every time i have a prob you always post i don't think there has been a time you haven't (cheeeeers)

[just vaux trev]

grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr

[Lee]

If its in the engine loom id make a guess its the signal for the temp guage on the standard car, but if your conversion was done properly the nova guage should be getting its signal from the nova car loom. its possible its not needed mate, dont get angry until something doesnt work lol

[just vaux trev]

/\ think im prob best put a new thread up when something doesn't work
when the engine is ready for 1st crank but would still like to know what wires/where and what sensors are needed to run a 2.0 8v in a nova ecomomically (spelling)
if anyone has or can do a muppets diagram would be appreaciated (spelling)
cheers once again lee

[Lee]

iirc from steves car, we used everything on the engine harness, there wasnt a spare plug anywhere bar a few small ones which fed auxillary stuff like the washer on the cavalier. Just needs a switched live, constant live and an earth to get it running. I honestly dont remember seeing the plug you put a pic up of, but a blue wire is water temp sensor on all vaux's of that age, so as i said, its either been bodged on or its not used.

Is the big 8 pin plug still on the engine harness feeding the starter / alternator etc..?

Is there a blue wire plugged into the thermostat housing?

[just vaux trev]

blue wire is plugged in just single wire' it's just one piece loom no breaks(8 pin)
sorry for asking this but of what you know what colours go where (engine starter ect)
as it loks like i have 3 wires going to the starter???

[Lee]

im pretty much convinced you dont need that plug then.

[Adam]

Look on the side of the head near the dizzy, see if theres a sensor there.
That plug is 100% a cts plug, tho it looks like its on a spi loom! Why a gsi would have a spi loom hanging about i have no idea lol

[just vaux trev]

/\ it's a lux>>> gsi looker (another)

[just vaux trev]

just waiting on roose pipes from chris astley then i'll just have to try it
and see what doesn't work

[gsiboy21]

is it for a knock senser

[just vaux trev]

are you sure where is it located:thumb:

[Steve]

Sorry to go off topic but I didnt know they did the pipes for the 2.0 8v conversion? I know they do it for the 16v as everyone seems to have a 16v nova lol

[Adam]

/\ it's a lux>>> gsi looker (another)
That explains it then.
Its the old spi engine loom :thumb:
Not needed, leave it undone.
