[pwuser151220154381]

first i thank for your endless support !! hats off !!
plus its good to investigate stuff in open forum so it could help anyone !!

and here is a open view of my current ecu !! ill write down the pins and share in a while !!

[Hassan1991]

no problem bhai.
now it will be easy. just follow this denotation of pinouts.
and trace the wiring. modify it if you need to.

here are the pins thats visible on my board

[Hassan1991]

20 - CF means A/C pressure relay switch
9 - NE- camshaft position
21 - NE camshaft/crankshaft position
6 - IGT ignition coils
7 - IGF signal

[Hassan1991]

what is the abbreviation of NC?

[pwuser151220154381]

so how to wire up it to my coil packs ?

i already have these pins connected

on ignition coil 1,4

brown wire is common ground
blue / yellow goes to pin 8 on connector 1
yellow goes to pin 6 on connector 1
black white is positive +12

On ignition coil 2,3

brown wire is common ground
blue / yellow goes to pin 8 on connector 1 (same as coild pack 1,4)
red/blue goes to pin 19 on connector 1
black white is positive +12

[pwuser151220154381]

bro i think the ecu pin outs are different in each model !!

[Hassan1991]

yes as i told before
pin 8 is for fan

[pwuser151220154381]

yes as i told beforepin 8 is for fan

what is FAN ?

[Hassan1991]

where 7 pin is connected?

[Hassan1991]

it's connected to radiator fan i think so. use to increase the rpm

[pwuser151220154381]

so my wiring doesnt match my ecu pins !! so what ECU will mathc my wiring harness !! time to scratch heads !!

[pwuser151220154381]

where 7 pin is connected?

the pin 7 is empty in my connector A

[Hassan1991]

Its the Ignition signal wire

[Hassan1991]

Connect 8 no pin to 7 and quote me what happens.

[Hassan1991]

Both coil one wire should be feed back which is IGF.

[pwuser151220154381]

bro it fired !! the engine started !! but i bought the ecu from the dealer !!

89661-10190 was the ecu that i had !! but didnt work !!

and i bout

89661 - 10170 it worked for me

still having some minor issues !! the engine is at high rpm at idle !!

[Hassan1991]

Great.
Now you got matching wiring.
Check the error, do the following
switch on the Ignition (don't start the car)
Short TE1 pinout with ground
Check light turns of and then blinks if there's any error code.

[pwuser151220154381]

bro please can you explain it a bit further i dont have a check engine light originally

[pwuser151220154381]

and bro the 5efe ECU will also fit the distributor less ignition engine !! good that i got the experience !!
