Wiring Diagram EP91

You should be able to use most of the origonal wiring in the corolla loom for the starting and charging circuits, you might only need to swap plugs over to suit.
All the other sensor wires you will need for the fte engine come from the big plug in the photos above, thats what you need to splice in.

I dont know about the corolla ecu, but if you open the fte ecu, the pins are labelled inside. You will probably need to splice the instrument cluster warning lights and other wires into the fte loom. Leave all the other wiring as is.

Once you start its not that difficult. Label each wire either side before you cut it and you wont loose track of where you have been.

same for the rolla ecu weeJohn

oh ya, havent been on in a while.corolla isn't labelled inside ECU...and the big connector(26pin) in the above pics is on my corolla, but not the glanza...(corolla is 26 and 16 pin connectors, glanza is 26, 16 and 12 pin!!!)

all toyota ecus are labeled on the pcb, so your rolla ecu is too.

putting a 3 plug ecu in a 2 plug car is not that difficult.
this is an adapter piece I made for a friend:

adapter loom :)

hey sagittariusman, whats the "pcb" you're on about, opened up the old 'rolla ECU I have and theres nothing labelled inside...


hey do you know any site where they have the ECU pinouts for the corolla 1995 4e-fe engine???personally havent had any luck since...




or if theres cash coming your way, could you make me an adapter loom ;-)





and do I need to use the glanza fusebox, as my corolla doesn't have 2 things-the "st coil" (so its badged on top of the fusebox) and the "EFI Pitcher" (also as on fusebox cover)

Hi,
the pcb is the main prinetd circuit board,
it looks like this including their descriptions:

I do have some 4e-fe pinouts but they're not all the same. it's best to have a look at your pcb again.

or if theres cash coming your way, could you make me an adapter loom ;-)
No problem but then I need to know the pinout of your 4e-fe too ;)
And you will have to cover the postage costs as I live in the netherlands :cool:

nope not neccessary.
If you want I can also adapt your rolla loom to the 4e-fte loom.
In that case I will need both ecu's and both looms to match eachother. The result would be something similar to what I've posted before (pics).

Saggi,

Just on the topic of being inside the ECU.. Have you ever opened an auto ECU and compared it with a manual?

1. ok, wil have a look at the "PCB" again and post you a pic :D


2. pinout???26pin and 16pin, if thats what you mean??
no probs as to postage ;-)


3. adapting the loom sounds good, although I have the 2 looms and have slightly started on the cutting...and have little bit of extra wiring for thr HKS Programmable Fuel Control....
do you need just the looms(engine loom, going from interior loom to fusebox only) and ECU's...?

Saggi,

yes I have :) even the manual glanza ecus have "auto" markings inside them like L, 1, 2, etc.
I have all ecus here (3 types manual, 2 types auto for GT and auto+manual for glanza)

that's how I made the original ecu pinouts as I have posted on the old forums (from where andrew/toyotasera.co.uk made another document with the same info but also with sera pinouts).

1) okay :)

2) pinout means the names of the pins. for example pin 1 of the small 16 pin plug is called +B1 which is 12V switched power.
almost all pins are labeled. pins that are not labeled are not used.

3) how bad is the damage? :p
repairing the loom is not a problem but keep in mind I do not make looms free of charge.
My asking price for a complete working loom is 25gbp per hour work with a maximum of 10 hours. Every hour more spent is my problem lol.
Also you have to pay for shipping the looms to me, and back from me to you.

- all wires that are soldered are protected with heatshrink.
- the solder used is high quality solder...not that cray you can buy at the D.I.Y. shop.
- loom will be taped and wrapped with that plastic ribbon stuff.

let me know what you think :)

yes, i know that no-one does anything out of the goodness of their hearts these days lol :p
the "damage isn't bad, I know exactly what goes where, so can put it back to the way it was before for you ;-)

If you want I'll send some solder (with high part flux) to you too, and some black insulation tape....?

nah that's not neccessary... I've got loads of that stuff lol

ok, PM me the adress i'l be sending stuff to...


the 2 engine loom's and ECU's.
wil I send the fuseboxes??

sagittarius, can I just ask you when you make the loom, do I need to trace back wires for the interior loom or fusebox to work???

I only need the following:
- 4e-fe engine loom
- 4e-fte engine loom
- 4e-fe ecu
- 4e-fte ecu
that's all :)
no fuseboxes are needed.
No wires need to be traced back as your original 4e-fe loom will be used as base-loom. The 4e-fte parts that are needed will be soldered into this loom.

I have all ecus here (3 types manual, 2 types auto for GT and auto+manual for glanza)

So the manual glanza ecus only have the markings, or can they actually run an autobox?

(It's difficult to find performance ecus for autos you see)

well I also followed the copper prints on the circuit board... and they seem to be running dead where normally should be some SMD resistors (smd stands for surface mounted devices which are very small. mostly these devices are around 1-2mm)
I don't think they are interchangable.
However I have seen some remapped automatic ecus on the yahoo auctions before.

Bugger, guess it's piggyback time then :haha:

Cheers for the firsthand, reliable info dude. Can't get this stuff anywhere else!

no need to put in everything from the starlet into your corolla.
just merge yourstarlet engine loom with the corolla loom. easy as that.
this way you do not have to match any interior plugs etc.
It's an old post but maybe someone can help. I have a 1998 Corolla E11 with a 4efe and I need to swap to a ep 91 4efte with AC. I am looking for a complete diagram with pictures of the connectors for the ECU loom connectors and for the fuse box loom connectors. I don't know how to merge them I think that the 4efte will need its loom and the extra loose connectors on the Corolla will need to be added later. I really need help to avoid mistakes. The ECU loom line from the Starlet ep91 is different than the Corolla E11 4efe. The distances under the hood are different. The ECU loom around the engine is easy besides a few connectors I don't recognize. I am worried about the Starlet fuse box loom with its connections to the engine. Is it going to be long as the Corolla loom and be easy to connect around the car? Who knows I found a ep82 connectors diagram with pictures form @alanmears. I'd need confirmation it works for the ep91 and I would need to find it for the Corolla. Hope you can help!
