OlberJ's Wiring Thread

[OlberJ]

Thought this deserved it's own thread as it could be useful for future swaps and i can't see anything specifically on the forum for it.

I've used the wiring guide from the front page (cheers Paul) and i have everything marked up on the 4age loom side. Now there's 1 wire on there that is not the right colour but it is in the right place on the N1 connector pin-out.

It's a kinda beige colour on the guide but in reality it's white with a black stripe. It's number "21 - ground". Now a i say, it's on the right place on the 4age loom side of the plug but it's the wrong colour. Can i assume this is the correct wire due to pin location as opposed to colour?

On the Camry side of the connector i still have 6 wires to locate.

Now i think Paul said that the camry came with all sorts of colours of wires so i'm not too worried just now. I take it i have to get the pin out for the camry plug and then trace back from there. Or are the :

Water Temp Guage
Injector relay
Tacho
Charge Fuse 5amp
Fuel pump
Engine Main Relay Pin 4

not on the 4th ECU plug?

If they're not on there, where are they? Or is it just a case of it's on the 4th ecu it's just different colours to the ones in the guide?

Not sure if i've got the pinouts for the Camry. Anyone got them?


Your help is much appreciated,

[weegaz22]

with regards to the wire being different its probably something as simple as it being a different year car from the car paul used in the swap, different years have revisions made to the wiring, hence why if you look in a haynes manul you need to pick out your proper year and model for your car before looking at the diagrams

[OlberJ]

Dinnae have any haynes manuals, never liked them :mrgreen:

Will check out the 3VZ manual i've got.

didnt mean to be specific, but usually any manual will have multiple wiring diagrams in it for different models/revision/years

[OlberJ]

Here's the wiring from the manual. It looks like the 4th ECU plug is on the right.

[OlberJ]

The plot thickens...

None of the wires in the guide diagram are on the 4th ECU plug, is that right?

Found all of the correct coloured wires apart from :

Speed Sensor - Pink/Yellow
Fuel Pump - Blue/Black
Check Engine Light - Green/Orange

Anyone know/can spot where these are likely to be?

For these ones i have 2 or more wires of the same colour :

Ground - Black/White x 2
Charge Fuse 5amp - Yellow x 2
Coilpack - Black x 3or4
Engine Main Relay Pin4 - Red/White x 2
Injector Relay - Red/White x 2

When i have 2 or more of these same coloured ones on the Camry side of the loom is it ok to connect either of these to the corresponding wire on the 4age side of the loom?


Cheers,

[weegaz22]

looks to me like the 4th plug on the ecu diagram above is mostly to do with the car being an automatic

id go more with the pinouts on the ecu than the colour of the wires
sorry its not much help

[OlberJ]

Now am uber confused. Just found these pin outs :

http://www.twobrutal.co.uk/forum/images/recovered/2007/10/5.gif

Are these the right ones? Would make more sense as i can see more of the correct items here.

What the hell was i looking at before?

[weegaz22]

are they not the same? cant really make out the lettering in the pinouts on the 1st diagram

[OlberJ]

They are, just the table is less clear on what does what. Think i've got it now though.

[OlberJ]

Still can't see Fuel pump or Check engine light on there.

[weegaz22]

fuel pump is on the COR is it not? just had a look at pauls guide on the V6

[OlberJ]

Right, now i'm really confused again.

I've got the pinout from Paul's guide and have located all the wires on the 4age side of the N1 connector.

What i can't match up is the descriptions of the wires on the 4age side and the names they're given on the Camry side to connect to. So am going to write a list and if anyone could tell me what they are on the Camry side i'd be most greatful.

Check Engine Light = Stop Light (E10-14) ?
Oil Light = ?
Injector Relay = ?
Water Temp Guage = Engine Coolant Temp Snsor (E8-4) ?
EFI Main Relay = ?
Speed Sensor = Speed Sensor 1 (E10-8) ?
Engine Main Relay Pin4 = ?
Tachometer = ?
Charge Fuse 5 amp = ?
Fuel Pump = ?
Ground = Power Ground 1 or 2 (E7 -13 or 26) ?

Here's the 4 plug ECU pinout's, are all these wires on here to connect to the N1?

It's pickling my noodle right now. Please help :freak3:

[weegaz22]

stop light isnt going to be check light, thats probably going to be the signal wire leading to the auto tranny so you can select drive when you have your foot on the brake, could be possibly e10-4?

[OlberJ]

I thought E10-4 would be the hazard light?

[weegaz22]

I thought E10-4 would be the hazard light?


why would the hazard lights be wired into the ecu?

[OlberJ]

Incase the ECU brakes down lol

Just what i thought, probably completely wrong. Electrics are not my forté.

[weegaz22]

dont quote me on this but i dont think the oil light will be on ecu either, same for fuel pump,
havent done an V6 conversion but just going on what ive known from working on cars for years, but each manufacturer has their own ways of doing things

[OlberJ]

right, so there's more pin-outs which i need for the other plugs.

Would make sense. Cheers.

[OlberJ]

Are SFI and EFI the same thing?

[weegaz22]

SFI usually means sequential fuel injection, EFI is electronic fuel injection, they are injection systems so with regards to your swap id say yes,(but again dont quote me on that lol) its just they inject fuel in different ways, sequential will fire injectors seperatly, where as EFI would probably fire them all at same time

[OlberJ]

Looking at JB's it's maybe a bit more complicated than i thought :

[weegaz22]

just go over it one wire at a time, if you look at it like in the pic you will just get confused and fucked off with it and never get it done

[OlberJ]

No, the problem is i don't know where to find these wires, not there's a lot of them.

Need someone in here who's dunnit already. Your help is appreciated though Gaz, ta.

[Paff]

Would love to help altho my brain was completly fried when we done mine so with the mk2 V6 guide, coupled with the mk1 in outs and Paul on the phone we (well Podge) worked mine out.

What COR you using, mk1 or camry as that will make a small difference as well.

[OlberJ]

Sticking to the mk1, Camry's been binned.

Is there pinouts on the mk2 guide? WIll have to read that.

[OlberJ]

Big thanks to Murf for his sparky skills.

Got the whole of the N1 connector wired up and tested. Just the 4 wires on the fusebox to sort and the battery cable to route.

2 things though :

On the original guide it has 2 engine fuses listed on the left side.

Engine Fuse 10amp
AM2 Fuse 7.5Amp

These don't get fixed to anything on the Camry side of the loom do they?

And what about these other wires on the COR?

http://www.twobrutal.co.uk/forum/images/recovered/2007/11/28.jpg

Do they have to be connected somehwere?


Cheers,

[Paul Woods]

they most certainly do young man....

http://www.twobrutal.co.uk/forum/images/recovered/2007/11/29.jpg

[OlberJ]

Cheers Sensai.

I'll add it to Murf's "to do" list. lol

[Murf]

Nice one Paul, i figured out the ground connection but had no idea for the rest!!

[Paul Woods]

also make sure the AFM W/B earth wire has continuity to ground,if it doesnt then ground it.

Oh and i cant see if the blue wire is connected up in that pic,if not then join it to the blue wire on the N1 connector :thumbsup:

[Murf]

yep,the blue wire is already done!

[OlberJ]

Ressurecting this thread jus to check some things.

I don't have the OPS on the engine yet and when i turn on the ignition the pressure shoots straight up to max, is this right?

I'm also only getting one red light in the middle of the bottom of the dash (!) < that one.

Any ideas?

[Paul Woods]

first off.... wtf is the OPS?

have you wired the alternator circuit up? sounds to me like its not wired properly on the alt side.

Unplug the alt 3 pin plug,switch igntion on and you should have 12v ish at all three terminals. :thumbsup:

[Paul Woods]

ah oil pressure sender....just worked it out,no i dont think thats normal,have you fitted the mk1 OPS?

[Gary Symons]

I seem to remember having a similar problem with the alt wiring on mine, after checking the wiring and fitting a different alternator it turned out that the alt plug on the wiring loom was knackered.

[hot-chili]

Why didn´t you use the MR2 COR it is no problem to use the old MR2 system.

[OlberJ]

Hi Chilli, yes i did use the mk1 COR as the Camry one got taken away with the shell.
