Crown UZS131 Wiring Diagram

The 1UZFE EGR Delete Kit is available for sale here.
hey elsupra

what types of plugs does the loom have

an old crown has 2 plugs and a 3rd goes to dash area

an ls400 ecu has 3 plugs and 4th goes to dash area


i have a spare ls400 ecu for sale if thats the one your after
im not sure if later model crowns used an ecu similar to ls400
like a majesta

i just wired up a late model 1uz think is was a celsior same plugs as a soarer 1uz

i know above it sounds like an easy job

this was into a 90 model hilux bloody thing took me 8 hrs from start to finish

alot of people think its only 5 or so wires

gettin engine running is only 1/3 the task
i can have most engines running in an hr

just gettin all the other externals to work is the time consuming part
 
Sideshow-
Thanks, I have the LS400 harness. Was actually able to find a used LS400 ECU locally. Your right getting it running was pretty easy. I still have not finish wiring all the externals yet. Havn't even started on the AC yet. But it running and pretty smooth. Posted a copy of the first dyno over on the Exhaust Clarification thread. The only real issue I have to work out now is the idle. I think the TPS needs adjusting or the ISC is going out since its starting to idle @1100 - 1300 and sometimes surges between 800 and 1300.
Thanks for all your help
 
Can someone reupload these diagrams or send me them?

the URLs have now been changed so the diagrams should load.
I changed ISPs so my old account and web address was shut down.

I can make the thread sticky if people think it is appropriate?

where is the Classicrown website?

GT,

The blue 6pin plug belongs to a steering shaft speed sensor. (See earlier post this section) If you look on the rear of your indicator/wiper control switch assembly you will find this sensor, it just looks like a black disc screwed to the rear of the assembly. The SSC wire also goes to this sensor. (Maybe you can trace this wire too) Mine has a 6pin plug, but only 5 wires. I need to connect my engine harness back up to see if the black and orange wires are a powered or receive a signal from the vehicle speed sensor.

It may send a signal to the power steering control unit which is located under the dash.

I think I have worked out the speed sensor problems with my conversion. Look on Classicrown in the electrical section for the post by Kuchie. I have found a speedo with a speed sensor built-in and found some more diagrams and I think this system should work.

Cheers,
Shane.


Look on Classicrown in the electrical section for the post by Kuchie? Is this a website? Sounds like it ewill have some useful info if we know where it is?

LS 400 engine and gearbox transplant wiring info req'd

I'm just wiring up the first of the LS400 engines into my Cobra replica and am wondering if there is an simple guide available for wiring up the the combined ECU and ECT used on the LS400.

The information on the Crown is very useful but a few pointers on the wiring used from guys who have transplanted the LS400 and its auto box into other vehicles would be very helpful and save me from a headache or two.

Any help gratefully received.

Cheers,

Tony

Hello,
The wiring diagrams for the Crown UZS131 Roayal Saloon can be found here. There are pinout diagrams and the schematic diagrams for the engine ECU and the transmission ECT. I cannot gaurantee they are 100% correct.

Hope this helps with your conversions.

Cheers

make sure all wires between engine ecu and auto ecu are connected

plus u need a converter for the either one of the speed signals

on a crown no speed signal goes directly to the ecu like the isngle ecu 1uzs
u need to do something

i really wanted to say pissssoff cause i offered them to bring it to my shop
