what an ubber useless thread

[napalm_27]

well thats helpful

[burgo]

well read what you put!!!! i ent a fooking mind reader, how do i know which car, engine, loom and so on it is???

[napalm_27]

orite sorry
its a 1.2 spi nova engine not sure what one but iv just literally cut away all the engine wires and ecu wires and left the main car loom now

[burgo]

and what are you planning to put in it?

[napalm_27]

c20ne mk3 astra loom
at the moment im just cutting down the nova loom
and hopefully going to make it into a plug and play loom

[Sloth]

jesus, right.....

get the glove box out, undo the ecu, and cut ALL the wires to the 2 ecu plugs. unwrap the loom that goes through the bulkhead ( remove the tape) and do the same in the bay. pull the wires INDIVIDUALLY (one at a time) until no more come out. you will be left with the dash feeds and the fule pump wire, and a few permanent lives and switched lives. now drill a hole at the top of the bulkhead at the drivers side, feed your astra loom through. pull the spare wires through from the bay under the glove box and back across the dash to the fuse box. connect em to the 3 small plugs and make sure to connect the fuel pump also. if the wires dont reach take the dash out, untape the dash loom, pull the wire across and retape it all. use the switcheds and permanents to feed the new loom. easy peasy. remember to tape it ALL up!
if this seems a bit complex then id stay with a 1.2 tbh, and build your skills, as the spi's are harder to do, and for a novice impossible....... its the ONLY way to do it.

iv got the loom in my living room lol
iv cut all the wires away already i was just asking just in case there was something there that shouldnt be cut thats all thanks for the little walk though tho may come in handy when i start fixing the looms together

[Sloth]

ha ha i did mine in car took 20 mins but i knew what i was doing, just trim the stuff to the ecu apart from the clock feeds. if ya aint got a haynes, get it and read it. otherwise you will fook it up!

[napalm_27]

clock feeds on which loom the astra or the nova loom?

[Sloth]

nova as they go from the ecu across the dash tom the clocks,and 3 iirc go from the engine to the clocks.alt, oil, and coolant iirc

[napalm_27]

orite well iv chopped them but i have a digi dash in my nova with the wires already cut on the plug so im just going to join them all back up to that

[Sloth]

oooops fail lol oh and you use the nova starting and charging loom.

[napalm_27]

iv only chopped the plug off so nothing that cant be reversed
and i was going to use the nova starting and charging loom
because its all there and its easier then messing abput trying to fit the astra one

[Sloth]

good good. if ya put the starting and charging loom on the lump when its out its easy, oh and take the alt off before it goes in mate. easier. done 5 of these now......

[napalm_27]

ok mate i usually do take them off when there coming out anyway you talking about the nova s/c loom on the engine before it goes in the nova so less fafing about once its in?

[Sloth]

yeah, makes it easy tbh. i leave the 2.0 main engine loom on aswell. manifold etc off, drop it in without the oil filter and bottom pulley on and it clears the leg. drop it in box down a t a 45 ish deg angle then push as far to the n/s and drop it down into the hole.

[napalm_27]

yer mate always do that it goes in easier
but iv never taken the oil filter and bottom pully off when doing it before may try it this time see if it makes a difference

On your engine loom, what plugs have you got that are left over?

ie do you have 1 plug in the engine bay or 3 coloured plugs near the ECU (like my guide I wrote).

[napalm_27]

i have one plug empty just were the loom comes through the bulk head is that what you mean?
but il go check quick

[The Simps]

what colour wires are on it?

[napalm_27]

brown and red/blue i think mate and my ecu has just got the 1 big plug on it cant find 3 small blocks around it but im taking out the dash tomorrow to get the loom out so il check then

[The Simps]

I'm more interested in whats on the engine loom as thats what needs connecting up!

If you can get pics then that would be great!
