Help needed with 1UZ and ID missing parts

**PRIMRK** · 14-11-2010, 10:58 PM

Now I’ve had some real trouble finding any wiring diagrams so I figured ill post a pic of each plug/questionable bit that I have hanging off my 1UZ-FE, as well as how many pins, what pins are used and what colour wire each pin uses and just any other info that may be helpful to someone who knows 1UZ's.

As far as I know this engine is out of a 1993 soarer. (please correct me if you believe this is wrong.)

Well here we go…

Pic 00: ECU
The only plug I could figure where it went was the 40 40 40 plug to the ECU

Pic 14:
Location: Right front of engine, it’s a battery terminal, the longer of the 2, is this + or -? I believe its + as I can sort of trace it to the starter but not 100% sure

Pic 15:
Location: Right front of engine, it’s a battery terminal, the Shorter of the 2, is this + or -?

Pic 16:
Location: Right front of engine, I’m fairly sure it’s an igniter plug, any one have a part number for the igniter as I have only got the one that sits on the top.

Pic 8 - Fuel Supply is always the screw on line, return in the slip on one.

Pics 9 and 10 - ignitors

Pics 14 and 15 - whichever bolts to the block is negative

Pic 16 - coil lead

Pic 19 - ISCV (or TRC depending on where it is in the loom)

Pic 20 - Alternator

Pic 23 - Power cable extender

Pic 25 - waste of time

Pic 26 - ISCV is missing

Pic 28 - tensioner pulley

Use toyodiy.com to get part numbers

**CrUZida** · 15-11-2010, 12:06 AM

This wil also help

**CrUZida** · 15-11-2010, 12:08 AM

And these

http://conceptual.net.au/~peewee1/wi...FE-pinouts.pdf
http://conceptual.net.au/~peewee1/wi...FE-diagram.pdf

Use these, get the multimeter out, and go pinning.

**PRIMRK** · 15-11-2010, 07:38 AM

Thanks for that, managed to find these part numbers.
Pic 16: Part number for ignition pack is 19532-50010
Pic 27: Part number of water inlet 16321-50010
Pic 28: Tensioner pulley part number 16603-50010

I cant find the ISCV in the part diagrams, not too sure what it dose so i don't even know where i should be looking.

**Supra967** · 15-11-2010, 10:25 AM

Idle speed control valve - does as the name implies. From memory the valve part (bit thats missing)should be same from few different cars. If you can't find one local I have a few - pm me

**AndyTTR** · 18-11-2010, 10:30 PM

I've written up a pin-out list for all the plugs that come out of the engine loom and connect to the body loom (UZZ30 / UZZ31 Soarer). You can find it here:

http://www.v-eight.com/tech_forum/vi...hp?f=59&t=1254

It has diagrams of the plugs which will help identify some of those in your pictures.

**PRIMRK** · 19-11-2010, 08:45 PM

Thanks for that, i had previously found that but for some reason all the information is displayed as a load of dots...

**AndyTTR** · 21-11-2010, 03:22 PM

Yeah, there's a corrupted version of it getting around... I think the speed limiting on rapidshare (where I originally hosted the files) screws around with the PDF format...
