love to help you but way too much kanji for me! you'll need someone who can read kanji and there are not too many foreigners with lots of kanji knowledge. just be patient :kiss:

will be beer baron :O really just after what a translation of what each wire is the stuff isnt that important

:kiss:

The bottom pic: (reading from the top)

White wire:AFM

Blue:Tacho

Green:Speedo

Orange:Fuel infection (trying to liven up a boring day)

Black:Non power

Red:POWER!!

The top pic doesn't really say anything. Just to plug the ECU connector cable into the engine computer wiring, which is what you are trying to do. And not to cut the engine computer's wires. And to check everything lots.

Sorry about the vagueness, it's a bit hard to know what's going on when you don't have the actual gear in front of you. If your not all sorted, then ask a few more questions/post a few more pics.

sorry to bring up an old thread but im about to install one of these, problem is the white wire is actually a double wire, that is split at the plug and goes to 2 different pins, can any one tell me what it says about it at the top of the wiring pic?

473 is about acceptable to me.

what are you on about mate? did I somehow offend you? I thought the sentence was pretty bloody simple. not many foreigners I know, even those that can speak japanese well and read and write kana, know many kanji. I honestly don't know what your problem is. half the time it seems to me you trawl the forum looking for an argument.

my point was this. not too many people, even amongst those studying japanese will know lots of kanji. he posted a thread for help, at that point in my study 2 years ago it was too much for me to read to help him. after one day he grew tired of waiting and bumped the thread. I simply pointed out that there are not huge reserves of people on the forum with the time and skill to read it for him and to just be patient (ie don't bump the thread every day). Not everyone reads the forum every day and for request like this sometimes it may take a few days for someone to respond.

now your japanese may be excellent and you may be a grand high master of kanji too but if you could not understand the simple message above I think perhaps your english comprehension skills are somewhat lacking.

Also consider the fact that this thread is over 18 months old.

sorry mate i wrote that pretty late, it came across a little differently to what i was wanting.

didnt mean to sound like an idiot. I have met a lot of people who are foreign and can read kanji very very well. Those people were all at the school I was in though.

i thought your generalization was about the world in general. not the forum. sorry about that.

you are right in saying on these forums though.

im guessing michael was, back then, in the same position i am in now, just got one and anxious to fit it.

I did pm michael to try and get some help with the remote for this dash and never got a reply so i dont want to hassle him any more.

A++ would read again.

this thread delivers :) even 3 years later.

w0rped did you ever get an answer about the double/white wire? maybe for gtr afms?

And is there are clearer requirement for orange? any injector pulse or something else?

my ecu is not on the instructions so I'm a bit stuck.

sorry I must mean something different. the unit came with a plug and about 7 wires. I don't know which wires I need to tap on the ECU, but the list above clarifies all except 1 - not sure what exactly I need to tap for the fuel?

Hey Duncan are you running the epson ej1 system too?

I see now, i think i did find out what it was for but i cant remember now and have lost all the wiring diagrams

    • Just had this happen to me too.  R32 GTR.   Also broke "just before going out onto the track" - someone up there is looking out for us... Very scary since I was about to do a narrow street course with zero run-off and curbs everywhere. Many people on here upgrading to billet uprights and R35 bearings?   Or buying new OEM knuckles?  I am not keen to replace with another s/h 30 year old fatigued part.
    • Top off with distilled water and see what happens. If you keep losing coolant then you know to start looking.
    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
