wiring 1jz help needed please

[wilbo666]

so far i have wired up EFI RELAY, start relay, fuel pump, computer, alternator, alt sensing wire.

thanks again

You need to be more specific mate. Wiring up the 'computer' doesn't tell me much

sorry by wiring up computer i man i plugged the thin in! lol

the engine loom has not been touched AT ALL.

All i have one is grabbed the 2 plugs that went to the soarer fuese box that operated strtr and efi relay and wired those 2 relays up.

so now i think my main issue is power for ignition (am1 fusible link) and injector fuse) both of these have contant positive coming in on side but i dont know where the wires go o the other side as i wrote above they go under dash on drivers side somewhere

[wilbo666]

To be honest mate you seem to be a bit out of your depth.

The plugs near the engine ECU have a number of important things on them that need to be wired up correctly, such as power to the injectors, power to the coils, water temp output to the dash, etc.

nah if someone else can do it, then i can too, ive never let anything beat me before.
i know i dont need all those plugs, because i remember i just had 2 or 3 just hanging in the breeze under there in my commodore.

ill figure it out on my own as i have before, cheers for the help up until now.

[88cameron88]

the 4 plugs i have left come down with the computer plugs.
2 grey, one white and one orange.
i dont car about water temp to dash or any shit like that, i just want the car to start.


trying to get the computer at work to load pics of them

[wilbo666]

If you have a multimeter you can trace back from the engine to the engine loom plugs

I.e.
-you know the injectors need power
-you can put one of the mulitmeter leads on the injector plug (one pin will go to the engine ecu directly and one will be supplied with power)
-you can test each of the pins on the body loom plugs until you find one that has continuity (zero ohms resistance, or most multimeters have a dedicated continuity mode these days)


From memory tho, injector power comes out on the squarish gery plug under the dash, the two larger middle pins from memory (It's on more than one pin, 3 cyls for each pin ).

this is the best pic i can get to load, thse are th 4 plugs i have left on the loom. on the soarer they plug in in the passenger footwell left hand side

[88cameron88]

thanks wilbo, yes i have been doing that with the multimeter.
i have found the 2 inj pins you speak of, just give them constant power?
what other ones do you think i will need, for ignitor etc.....

thanks again

I'd suggest reading my wiki...

This pin is connected to Ground inside the ECU as required to turn the fuel injector ON. The fuel injector should be wired with one side of the solenoid connected to battery voltage (Ignition switched) and one side of the fuel injector connected to this ECU pin.

And also looking at this wiring diagram would show you similar

I'd maybe suggest the following plan of attack for you...
-Find JZZ30 engine ECU pinout (google )
-Make a list of the pins you think you need to connect after reading what each pin does - I'd suggest my wiki should be able to tell you what most of the pins do (the 2JZGTE has most (all?) of the pins JZZ30 does ) wilbo666 / 2JZ-GTE JZS147 Aristo Engine Wiring
-Trace the pins you need to connect to where they come out on the body loom plugs and connect them as required


What do you think?

now you have confused me with these 2 ecu pins... above you told me they needed power...

"".e.
-you know the injectors need power
-you can put one of the mulitmeter leads on the injector plug (one pin will go to the engine ecu directly and one will be supplied with power)
-you can test each of the pins on the body loom plugs until you find one that has continuity (zero ohms resistance, or most multimeters have a dedicated continuity mode these days)

i allready have an ecu pinout, what i think i need is a pinout for the body loom plugs.... i found one during my searching but its not right...

so.. do these 2 injector pins on the body loom need to go to power or earth???

[88cameron88]

ive just looked through your pinouts and info on each wire on your wiki..

so the injectors earth inside the ecu, so the 2 thick wires for the injectors you have been speaking of do go to ignition switched positive.??????

i need a pinout for those 4 body loom plugs..

here is the ecu pinout i have..

Google Images

on the above link where there are highlights black and red, should i be cutting these wires after they exit the ecu and running them to positive and negative as says??

[88cameron88]

ok ive managed to find a decent pinout for the body loom plugs.
on the IJ1 plug i have a red wire (fuel) green wire (fuel) red/green wire (fuel) and black/red wire (fuel main)...
what do i run these to?????

[BLK_20v]

Sort out m-relay, injector power, bat, +bat , ignitor power, coil power and the car will start...

Guessing will blow transistors on the ecu

can you try explaining that in a little bit simpler terms???
and whats with your "guessing" comment???

can you tell me what wires i need to send to positive????

as in what wires on those 4 body loom plugs to i need to send to positive for the car to start???
also what i need to earth if any...
what is the "m" relay?

[wilbo666]

ok, here is where im at.
using the ecu pinout i linked in my thread i have found what needs to be earthed off the ecu also where to run
battery wire.
ign wire
the +b and +b1 wire (to main relay)

now the main relay... is this different to the efi relay???

if it is, how do i wire up the main relay?

I think you will find that all of the earths for the engine ECU will already be terminated back to the intake manifold etc, as long as you ground the engine block the engine ECU should have its grounds connected


The wiring diagram I have only shows the one relay related to the engine ECU and that is the Main EFI Relay. The Main EFI Relay is triggered by the engine ECU M-REL pin. Again see my below link...
