Have you ever considered reading the @#$@#$@#$@ manual?
You can download them from the stickies in this forum or the 2nd gen forum.

I don't know FCs so can't be of any help beyond that.

You may want to post more information about your car, such as year, and turbo or non-turbo. If you just happen to have an 86 or 87 non turbo, I'm pulling my UIM off on Saturday if you can wait til then.

Why did you take off the injector clips in the first place?

its usually not the cars fault. but the person working on it.

ever consider labeling wires when removing them? and if the harness is layed on the motor correctly. the length of the wires should fit perfect to each injector. pretty basic stuff... sell your car before you contribute to the "rotarys suck, they always blow" stereo type, because you broke the car from misuse and bad mechanics.

Think before you take stuff apart and ALWAYS label. If that fails, give as much info as possible on your 7club post.

Definitely be more specific as far as what your working on, from your previous posts it says you have an 88 t2 (swap?). Also the wiring harness you're trying to put on this t2, is it an n/a wiring harness? follow the manuals (haynes and fsm) and look for pictures online. I'm taking the intake on my 88 t2 (stock though) today so i can let you know for sure, maybe take a pic or sumthin, take your time and be patient.

^ Is it even possible to run an N/A harness for a TII swap?

The manual should actually be of great help. Contained within it are full wiring diagrams. The FSM is a little daunting, so start with the diagrams in the back of the Haynes manual. They show you wire colours, which you can correspond with the colours in the harness. EM is the emissions harness, or the one that connects to the injectors. E is the engine harness, or the one that connects to the starter and CAS. F is the front harness, or the harness that runs along the drivers firewall.

Using the diagrams, you can figure out where each plug goes based on wire colours. And then next time, you will know to make notes or at least label wires before you remove them.

If this is the first time you have worked on a car, you need to take a deep breath and stand back for a few minutes. You'll find similar situations with all fuel injected vehicles: all injector connectors will be the same and the only way you will be able to put them back is via labels or the diagrams in the service manual.

Aaron has some good info. Ignore the unhelpful ones. No need to get riled up. Its a free user forum afterall.


Anytime you swap a different motor setup into a car, you will have to deal with the wiring issues and general electrical control issues.

If you think the TII to NA swap is hard, don't try swapping in a WRX motor into a Subie, or a V8 into the FC chassis is even worse - lots more wires there.

Why is the NA harness being taken out and replaced by a TII harness? You're just introducing a wiring headache. The NA harness will easily convert to work with the TII ECU, but the TII harness will need re-pining to work correctly with the rest of the NA wiring. Click the link in my sig, and pay close attention to the wiring and ECU pin info I put in there.

Just curious, how much wiring is involved with the v8 swap over a TII from a N/A.

Also, the issues you are dealing with are not rotary specific. You would encounter these difficulties with any other type of car, if you were doing this kind of swap on them.

Get ahold of yourself man! You can rant if you want to, and give everyone a bad opinion of you, but it really comes down to the fact that you entered into a project without the necessary knowledge and preparation.

If you want to extract useful information from the members of this forum, then you might try treating the subject, and the members, with a tad more respect and courtesy.

There are years worth of information already stored on this site, and if you take a little time to do some searching, I'm sure you will find that you are not the first person to run into these issues. I know for a fact that there are many people who have already done exactly what you are attempting, and several of them have taken the time to create very nice writeups on the task.

But when you come into any forum, spouting anger and frustration like you have, and (frankly) asking to be spoon fed rather than doing your homework, those who do have the knoweldge you seek may not be even willing to help you.

Really, take some deep breaths, crack a cold beer, and run a couple of searches. You might be surprised at what you find. Best of luck to you, and your project...

ok, let me say this before i read the rest of your posts.
im not new at mechanics. ive been a 240 kind of guy and ive had over 10 of them and i thought id try something new. ive always liked the fc but never really the motor, but i wanted something new and decided to give it a shot. i BOUGHT the car WITH the motor swapped. ive done some crazy motor swaps. if i would have been showed to rx7s when i first got into 240s it would be a different story. i was 15 when i bought my first s13 and swapped in a sr. did my first sr build at 16. im not a ******* noob at mechanics nor engines nor anything about cars except for rotarys.

If someone would just post a picture of a TII with the UIM OFF i think id be fine.

PS i was told to buy a TII harness and it would work...thats it.


RotaryRocket: i dont do words, i need pictures.

but whatever, i guess ill always be one of those people who are against rotarys.

MODS, please delete thread

Be nice guys. Help him if you can. He is new and this is the newbie section.

If anyone has a pic of the setup in question, please post it.



huntingcorn - while pics might be helpful, do spend some time in the manual. And take Kentetsu's advice. It is Friday. Grab yourself a brew and come back to the project with a clearer head tomorrow.

Huntingcorn, you ignored my question. I pointed out a HUGE way to save yourself some time and headaches, but if you want to ignore it, that's fine by me. A lot of people think they NEED a TII harness, but they're flat out wrong. I can't tell you how many times I've posted the same thing over and over again. If this little issue is giving you a heart attack, just want until you have to repin the harness where it meets the front harness plug.


If you insist on continuing to use a TII EM harness, the pictures you need are called wiring diagrams & they're free to download. Each injector has different colored wires, which will make telling them apart easy. A picture with the UIM off isn't going to tell you much if the harness is out of place on your end. You can't see the wire colors in a picture like that, since they'll be wrapped up.

Injector wire colors @ ECU:
Front primary: LG
Rear primary: LG/B
Rear secondary: LG/R
Front secondary: LG/W

This may be the noob section, but the forum rules still apply.

Please clean up your posts quickly, or you'll get a one-way ticket out of here...... then you won't have to worry about 'rotorys.'

thanks

i apologize to everyone for being a #$%^
I had friend look at it today and he said the wirign for the ignition coils was wrong sicne its a 88 base with a S4 TII swap.
anywhere i can get the wiring diagram/directions?
also i looked at the injector plug wires and there like all the same colors. kind of off white base with the same color stripe (black, something, black, same, black, same, etc.) there all the same. a picture will help a lot. also the only thing that i could plug the wiring harness into was the alternator/injectors/TPS. something wrong wit hthat? shouldnt the harness plug into more things?


FOR the injectors what i was talking about ealrier, its the actual plugs themselves i cant figure out which one goes where?
not where it plugs into the ecu

You can find the Factory Service Manual in the 2nd gen FAQ thread stickied in this forum:

The diagrams and such should be in there.

The ignition coil wiring between the NA and TII is exactly the same. As the coils are plugged into the body harness, this does not get changed during a swap.

As for the injector colours, light green is front primary, light green/black is rear primary, light green/white is front secondary, and light green/red is rear secondary. These colours are carried all the way from the ECU to the injector plugs.
