1UZFE Wiring

[highiq]

Hi all,

Nowe I know this question may have been asked a few times in the past but I'm in urgent need to get the wiring data in a simple format to hook wire up a 1UZFE engine to the standard ECU wbut will have a Supra 5-speed behind it, not the auto.

Any help would be great, thanks all.

what car did it come from? the crown motor would be easiest since it had a separate ecu from the trans, but i think it's still possible to do it with others.

ps, i have a crown ecu if need be.

Came from a lexus fron cut

lexus what? sc400, or ls400? there are lots of variants of the 1uz

My wrong...came from a Soarer UZZ30 Coupe

Resurrecting a dead thread here but do you still have the pin out diagram for your crown ecu? I have a 1uz from an LS400 with a crown ecu i'm trying to splice together. Need the pin out diagram for the ecu and a wiring diagram for the ls400 (I think i've found a wiring diagram but it was from an 'unknown' engine so a bit iffy on it)

Also was told that a 7m had a similiar plug to use to splice the two together, which i've found out to be wrong, anyone know what plug I can readily find to use? is a 40p plug.

If anyone can help, that'd be great.

40 pin plug would be from a ~93-98 model. 2JZ's in turbo and non turbo have the same plug.
What sort of crown ecu are you trying to use? A mid 90's thing?

Yea, from a Crown Majesta. Time to raid a jza80 then, heh.

DONT DO IT!!!!!!

Find a loom and ecu that is complete.

The savings in $$ is NOT worth the headache of trying to do what you are planning.

[Quint]

You're most likely right, but, you got to try these things atleast once .

Just need the pin-out diagram for the ECU and then I'll be able to see if it's do-able. If anyone can help, cheers.

I'll let you know if things go tits up, CrUZida, so you can say 'told ya so'.

I'm in search for the subj.,too . Only could find a '90 aristo thing, but mine is from late-90's crown. Got the complete wiring, only need to power it properly.

[CrUZida]

What part number is the ECU and what is the pin configuration?

[George]

Will get to the car soon to check out the marking. The engine has no VVTi and no distributor either. ECU looks like 2JZ-GTE's one with 4 or 5 connectors, each having several rows of pins.

[George]

p/s The ECU is 89661-3A080, has 4 connectors: 34,22,16 and 28 pins
