95 ra does anyone know anything about this ecu ..it has wrote on it lap information ..caution for competition use only
7k ....22611ac710...a18-000 d22 .lap serial number 1281 any imformation would be great
also there is a metal box about 6x4 inches looks like a small ecu under the dash on the drivers side ..it has on it stia 32520aa000 fuji heavy industries ltd
ku11100101 robin tech ....9510100561 made in japan ...any imformation would be great ...thanks
also i have looked at the threads on here for wiring diagrams and cant seem to find one that covers my car ..its a 95 ra does anyone know where i can get one from ...thanks again

I would guess that the smaller ECU is a diff controller and your car is an STI RA. The factory engine ECU is the one in the passenger footwell. What exactly do you want to know?

great i was hoping you would say that about the diff controller now i just need to know how to wire it up ...thanks
i wanted to know if that was a trick ecu or is just a standerd one ..i was told when i got it that it was a trick one

hazy

sorry the ecu also has wrote on it ....caution for competition use only

ZEN Performance

so does it have a DCCD centre diff? I will check my own DCCD diff ECU. What needs wiring up?

hazy

the car is an sti ra 95 with a dccd ..we are turning it into a rally car and have took out the wiring for hand brake .i have since found out that when you pull the handbrake on it cuts out the diff so you can do handbrake turns ..if this is wright i need to know how to put them back as the guy who took them out didnt take any notice

ZEN Performance

okay well that explains that. The handbrake does unlock the diff, but you may also consider doing some other changes like making the diff lock with with brake pedal. I wired in my own DCCD into a non-dccd car, so should be able to dig out some info.

hazy

that sounds great ...anything you got on it would be much appreciated ...thanks very much

old post but does anyone have any info on the pinouts of the dccd controller so i know what to chop and splice into on my sti loom?

iv got the clocks etc

i dont know what gos where on the wiring loom front though and its annoying

or can anyone offer any advice on what wires i need to use and where to connect them to in a colour coded fashion

any help would be much appreciated

cheers

The early diff controller are very easy to wire up, if you still have most of the origianl car loom then you just need to add the handbrake wire in to get it back to standard. Handbrake is pin 8 on the larger of the 2 plugs

Or if you have no wiring at all for it make up a small loom for the diff ecu, all you need is power and ground, thuumbwheel, handbrake and a pair of wires for the diff coil.

I did this in my V2 sti when i went to RA runnning gear.

If you are building a competition car then budget for a diff controller and wire it up properly. So many people dont bother but it makes so much difference

iv got the whole car and loom but i want to cut out the dccd part of the loom so i can run it in any shell with ease

i want to wire the clocks thumbwheel and dccd ecu in

there are 2 plugs on the dccd controller are you saying one is redundant?

il get info and wire colours on it soon and put up what ivb got and then if you are up on the ecelctronics then that would be a good help

if not im gonna have to cut the loom to pieces to see what gos where and try and sort it out

im really struggling to determine the lives and earths etc as wire chop and splice into eachother in about four or five places

il confirm what wires do this when im nearer the car

early controllers are 2 plug, later ones are single plug.

You can pull out all the diff wiring from an OEM loom, just take your time and follow it through. You dont need to connect to the clocks to make it work

Easiest way is to make up a loom to be honest. In fact, i have my one that i could sell you?

PM me if you are interested,

i want the lights to work though as iv got everything there to do it

iv just done a drawing off the pin outs on the dccd controller and just need a few things clearing up

if i could upload pictures it would be a hel but here gos:-

with the writing on the dccd controller on top and the plugs in front of you i have labeleebd the pins on the left 20 pin plug 1-10 along the top and then 11-20 along the bottom

1 - blue
2 - blue with orange/brown stripe
3 - red with blue stripe
4 - pale green with yellow stripe
5 -
6 -
7 -
8 -
9 -
10 - white with blue stripe (to thumb wheel)
11 - pale pink
12 - blue with white stripe
13 - yellow with blue stripe
14 - blue with black stripe
15 -
16 -
17 -
18 - red with orange stripe (to hand brake)
19 - green (to thumb wheel)
20 - white with green stripe (to thumb wheel)

here is the pin outs of the right hand plug labelled in the same way from 1-8 on the top though and 9-16 on the bottom

spaces indicate a blank pin/no wire output

1 - black (earth)
2 - black (earth)
3 -
4 -
5 -
6 - black (earth)
7 - black (earth)
8 - dark green (to diff/gearbox)
9 - pale green with white stripe (to fuse box by drivers kick plate)
10 - pale green with white stripe (spliced into pin 9)
11 -
12 -
13 -
14 - red (to diff/gearbox)
15 - red (to diff/gearbox)
16 - red with white stripe

i need a few wires identifying colour wise so i know what they are to from the green pug that goes on the clocks

i think im pretty close to sorting it though now

got one pae green wire that gos the the fusebox...iv got an open pin in the fusebox on the other car so il push it in and see if it works when i get closer to fitting the wiring!

d.kenny

a few of them wires are wrong iv just double checked

iv got a pink connector that gos to a round electrical component to

iv dentified all the wires except for one which is a red wire

the remaining ones go back to the dccd controller

can anyone shed any light as to what this may be?

cheers
