Help Finishing The Wiring On 4age Into Ae86

[Nebuchernezzer]

While dad is busy painting his AE86 i'm finishing off the wiring for him.

The conversion is AE82 bigport 4AGE into oz AE86.

The engine loom is JDM AE86 but the ECU is from a oz spec AE82 (as far as i know any 16V ECU will do, just the maps differ).

What we have working so far:

Alternator

Starter motor

Ignition (get a nice beefy spark when turned over!)

Fuel pump

 

Having a few problems wiring up the injectors. Checking at the ECU pins the injectors have no power.

I'm thinking that this yellow wire in this picture (the wire in the middle of the plug) is supposed to be connected to the ignition switch. With it connected to power i get the required voltage at the injector pins on the ECU with the ignition at ON. The voltage measured at the ECU on the injector wires falls off slowly when the ignition is turned off instead of just dropping to 0 instantly, seems odd but i don't know if it's good or bad.

This is the ECU side of the plug by the way (JDM end).

And this is the oz side of the plug as you can see the yellow and black and orange wires don't exist on this side (two empty holes).

Anyways thats as far as i've managed to get. I guess my next course of action is to check the wires from the crank angle sensor to the ECU (2 wires).

Also i would really like to know what the top wire in these photos is (black and orange wire), it's present on the JDM loom but not on the oz spec loom, do i need it for somthing?

Also this is the location of the plug in the engine bay by the way, at the back there.

JDM side to the right of the photo, oz side to the left.

Also one final thing, the ECU plug is OEM on two of the plugs however the plug that connects to interior things like the dash etc has been left off, only the constant power, and the two main relays have been connected on it, am i missing anything there?

There are a few pins which i'm unsure as to what they do. According to a post i made on toymods someone else had just the pins i have wired up here done on his car and it worked fine. However i'd like to confirm if possible.

They are:

Variable resistor (possibly for the fuel pump? i've wired the fuel pump up separately from the OEM setup.

Fail safe relay.

Circuit opening relay

Warning lamp (check engine light?)

Thanks

This might be handy, Part of the info I compiled on the FAQ - http://www.rollaclub.com/faq/

 

ECU Pinouts

 

AE82 Corolla 4AGE - (Largeport / TVIS / MAP)

 

Toyota Part Number: 89661-12080

 

Nippon Denso Part Number: 175700-0561

On the 14 pin Connector I'd say you would use the 4 on the end (battery power and water temp)..

Thanks.

I found some info on club 4AG this morning that might help me somewhat to.

Got to go sit down with the diagrams and the car and see what i can sus out, i'm sure i'm only missing one or two wires to get it running.

Your injectors are ground switched, so it's a little strange for there to be power there. I did this loom conversion with a mate 2 weeks ago. We just added a switched 12V feed for the TVIS and the injectors. Is the injector fuse still present? It plugs into a random 2 prong round plug behind the head. Also make sure the resistor pack for the injectors is still there too.

 

Hope this helps a bit.

where is the resistor pack located? i will be using a standard ECU and loom in the next month. I don't remember seeing them amongst my wiring spaghetti.

I can remember that it had a right angle 2 prong blue plug. Somwhere near the dizzy section of the wiring. I think that's it anyhow, efi don't need ballasts on the coil.

Where is the resistor pack located?

I've not managed to fine any plug in fuse, i found one on a spare AE82 loom but i'm unable to locate anything similar on the AE86 loom.

Thanks
