5m-e to 2jz-ge wiring help.

[wilbo666]

Ok so basically this is what I need to do?

Pretty well...but it would also help if you had an idea why you were doing things, as opposed to just blindly following info.

I noticed that in this guide for the 5m-ge he calls the connectors

IK1 and IK2.. are they the same as II1 and IJ2?

I noticed in that thread that he is talking about a GS300 2JZGE, not a JZA80 one Note how the plugs look very different - they aren't the same

Also, I have no idea what the iscv is and this is the first ive heard of it..

The ISCV is the Idle Speed Control Valve, and believe it or not it's used to control the engine idle speed.

You want it to work.

To make it work you need to use the engine ECU output M-REL to trigger a relay that provides relay switched power to the ISCV and engine ECU (connect the M-REL switched power to the pin/s marked +B). Again read the link I posted.

Also, sorry I also forgot to mention that the +B connection is on pin 3 of the 3 pin black plug in the engine bay.

Edit: Also, my engine is running a MAP sensor instead of an AFM

Yes I know, you've mentioned this about a thousand times already.

Once I do these II1 and IJ1 wiring, will the car start? or am I also suppose to wire up the (B) ecu plug to the 5m-e harness

which would be these 4 wires.

Terminal 1 is ignition switch power
Terminal 24 gets wired to pin 8 on the 8 pin under the bonnet. (main relay coil) or is it wired back through the ecu and can be left out?
Terminal 31 and 32 are also for the EFI main relay, so, do they need to be wired up the 8 pin plug aswell? as it says on the diagram (Needs battery voltage, so id assume so.. right?)
Terminal 33 is BATT, and needs to be wired to constant?

Yes once you wire it up, it should start...

You also need to learn how to use a multimeter A multimeter can be used to 'trace' wires and see where they go.

If you traced the wires from the 40pin engine ECU plug you would find the following

B-1 (IGSW) connects to the plug II1-13, so when you connect up the II1 plug you connect this
B-24 (M-REL) connects to EA1-8
B-31&B-32 connect to EA3-3
B33 connects to EA1-4

EA1 = 8 pin engine bay plug
EA3 = 3 pin engine bay plug

Sorry for all the probably dumb questions, but I'm an 18 year old noob doing his first swap ever lol........

We all start somewhere But it's poor form to get angry at the internets because it isn't serving you everything you need on a platter eh.


FYI, the easiest way to get the engine wired in, is to have both sides of the II1, IJ1, EA1, EA3 plugs, that way if you need to remove the engine at a later date you just unplug the engine to body loom plugs (as you would if the engine was still in a JZA80).

I hope this makes sense, please search and then ask what isn't clear.

Cheers

Ive been at the thing with a multimeter all morning and this is how I have it wired right now

It wont start like this.

II1 Connector:
II1-pin 7: I don't have a pin 7.
II1- pin 13: Have supplied with ignition switched power

II1 Connector:
IJ1-1: have supplied with ignition switched power.
IJ1-4: Just bridged the connection under the bonnet so it runs while the ignition is on.
IJ1-9: have supplied with ignition switched power.


8 pin Connector
Pin 4: Have wired pin for to battery terminal POSITIVE, used fusible link
Pin 8: Dont know what to wire this to in the engine side.


2jz-ecu plug B connector

Pin 1: Wired to ignition switched power
pin 24: wired to ignition switched power
pin 31: wired to 8 pin plug pin 4 (constant power)
pin 33: Have wired to 8 pin plug 4 (constant power)

From here to get it running, what things do I need to supply with constant power, ignition switched, or turn over power (Power when engine is cranking over)

Thank you for your help so far man, You are literally saving my life right now haha

[wilbo666]

So, apparently it runs now

All thanks to you Willbo, Really really helped me out man.


I'm going over my wiring now and redoing all the connections properly now.

Thanks again Will

[CELICASUPRA7M]

congrats on the first start
You got kicked out of mcdonalds, just in case you forgot lol.

[Shane~182]

Haha yeah I remember, unfortunately lol.. I should probably clean my youtube account

[wilbo666]

I've finished my JZA80 2JZ-GE engine wiring wiki, might be useful for others and future reference. By all means there might be some mistakes so let me know if you come across any.

Looks good Wilbo

I rewired allt he stuff today, and did everything with heat shrink soldering and proper fuses.

Also, I made up that little COR trigger for the FPC pin on the ecu, so I will wire that in tomorrow or something

i fucking WISH this thread was about a 1JZGTE.

so awesome

[midnight_purple_GA70]

i fucking WISH this thread was about a 1JZGTE.

so awesome

in principle its mostly the same for getting it up and running...
its pretty suprising really how many things dont "need" to be connected for the motor to run...

[wilbo666]

i fucking WISH this thread was about a 1JZGTE.

so awesome

midnight_purple_GA70 is pretty well right

Have you read through my wiki where I detail what all the engine ECU pins do?! Have a look at them, and then have a look at the pinout of the 1jzgte you have (what flavor 1jz do you have?) and then work out how to connect them given the information in my wiki

...I also recall Shane~182 saying he was going to do a write up tho!

Cheers

My 1JZ is from JZA70R (same one from my Z20)
ECU / Dash wiring is pretty straight forward seeing as speedo is controlled by cable and tacho is obvious + tacho adapter.

Its mainly the circuit open relay to control fuel and then the fusebox area in the engine bay.

I had a lookie at the wiki (using link u posted on the last page)
Makes total sense.
So if i find my 1JZGTE ECU pinouts i can adjust my loom in a similar way to the 2JZGte loom mentioned in your wiki ?

Wonder if it makes any difference that i have a powerFC... hrrmm

[Admiral coFF33]

Also i have R154 and no Hydrogayfan and no aircon, so no need to consider any of that wiring,
I found this also :

http://www.1jz.com/tech/docs/wiring/EA21989.pdf

Shows the plug i believe is the one next to the ignitor big fat roundish grey one ?

Pins : 1, 2 and 5 need 12v+ ?
Pins : 7 is ground ?
Pins: The rest i dont know ?????
Then :

http://www.1jz.com/tech/docs/wiring/IG1w-MT(1989+).pdf

Instead of connecting to : "MA71 M1 Male"
Splices into this guy from page one of this thread :

http://bambizoku.files.wordpress.com...cu-pinouts.png



Only info i cant find at all is info on what this plug is for:

http://www.1jz.com/tech/docs/wiring/IH1(90-92).pdf
http://www.1jz.com/tech/docs/wiring/IH2w-MT(1989+).pdf


It seems that its only for ABS / TEMS/ CRUISE CONTROL etc ...

which i dont have in the MA61.

[midnight_purple_GA70]

first with the fuse box wiring do you have both sides to the IG1 plug from the jza70?

next you need to locate the MA61 version of the MA71 connector C1
shown in this link http://www.1jz.com/tech/docs/wiring/EA21989.pdf

cut the jza70 IG1 wiring off about 15cm after the plug on the fuse box side
Join pin 1 B-Y to the correstponding ma61 B-Y (note this might not be the right colour you need an ma61 wiring diagram to decipher what does what)
join pin 2 B-O to the correstponding ma61 B-Y (note this might not be the right colour you need an ma61 wiring diagram to decipher what does what)
join pin 5 B-O to the correstponding ma61 B-Y (note this might not be the right colour you need an ma61 wiring diagram to decipher what does what)

make sure that the jza70 alternator wiring runs through to the alternator via the engine loom
if it does proceed to join the following
pin 10 to the pin 2 (check with an ma61 alt pinout) this should go to your ma61 dash batt light
pin 11 to the pin 1 (check with an ma61 alt pinout) this should be going into the fuse box and with a battery connected should read 12v at all times
pin 12 to the pin 3 (check with an ma61 alt pinout) which should get 12v with ignition on and 0v with ignition off...

then you need to go to under the dash and get the jza70 IH1 plug and find the equivalent version from the ma61

then you can start connecting up those bits... the big thick B-W wire should go to your starter motor and the big thick B-O should go to injectors coils ecu ignitor etc etc
thats all i have time for at this point but its not too difficult

should be fine working with the PFC as the ecu plug "shouldnt" need to be touched and its my understanding that the PFC just piggybacks on a patch loom or completely replaces the stock ecu? could be wrong on that as i havent played with one

Follow my main wiki link in my signature - I added info on COR the other day

Correct, the main problem is that I don't know of any decent jza70 body loom pinouts, however if you have the engine ECU pinouts and the engine loom / engine in front of you then you can use a multimeter to trace the body loom pinouts...

Near the fuse box you pretty well just need constant battery and the M-REL +B output (I suggest changing the trigger for the existing MA61 main EFI relay from Ignition to M-REL) off the top of my head...

Re Alternator wiring the MA61 stuff should just plug in


I also suggested in a PM that you buy the JDM JZA70 wiring book so we can make a proper / decent guide, something to think about

Wonder if it makes any difference that i have a powerFC... hrrmm

It shouldn't as power FC are plug and play.
