Anyone out there has manual ECU with three rows of pins like mine? Mine is out of 98 T100 2wd manual.
What are the wiring layout? Especially on E4 connector.

 

Why are you using that ECU?

:wabbit2:

 

I have manual trans. the ECU number checked out as a manual one from the dealer 98 T100 2wd manual.

 

Did TIS not have the EWD's for that year??

 

All the manuals that I've seen so far has two rows of pins for the connectors for 5spd ECU. Maybe they're the same?

my ECU number is 89661-34350

 

Why are you using a 2WD ECU? I'm missing something.

:wabbit2:

 

Do I really need 4WD ECU? Is it just for the 4wd light?
The engine came from 2wd auto T100.

 

I think you are fine with the 2x4 ECM.

Have you checked TIS like hamish asked?

 

what's TIS? I'm not familiar with it

 

Should have al the information you need. Pay like $15 for a couple of days and you can download all the diagrams you can for you vehicle and motor.

Won't he have codes with a 2WD ECU Jason?

:wabbit2:

 

he shouldn't. The ecu just won't know that there is 4wd. btw does anybody know why the ecu needs to know when the a/c is on, 4wd, or CC?? I have always been curious about this. Does it change the fuel map or something? I am pretty sure it doesn't supply the power for those items.

 

I think when you turn on the AC, the idle is higher. I'm guessing that the ECU control the idle speed.
Dunno about 4wd.

I've already have the 96 T100 manual and it shows the 5spd ECU as a two rows not 3 rows. Does the site allow you to search by the ECU part no.? I'm afraid that it only goes by the year of the vehicle. That won't help me.

 

I am willing to bet that your ecu is 98 or newer

 

for the ac, the 3.0 used vacum for the idle up. And the 3.4 is computer controlled. I have no idea why it needs to know when its in 4x4 or cc... I'll figure it out someday.

 

word!
