i have dona a 1G-GTE conversion and am having trouble locating the water temp gauge. i see the GTE ECU has a THW pin which is meant to be the water temp sensor. is this the same sensor as the one measure by the gauge or are there separator sensors?

The temp sensor for the gauge, is completely different to the one used by the engine. You will find the temp sensor you need for your gauge will come in on a plug that does NOT plug into the ECU (it would normally plug into the cars body loom).
It will be a yellow wire with a green stripe, both in your 1ggte loom and in the GZ10's body loom. (I'll be very surprised if it is otherwise!)
Cheers

SP1 is speed sensor 1 input
SP2 is speed sensor 2 input
FPR is Fuel Pump Relay
W is Check Engine Light
M-REL is Main Relay
NSW is Neutral Switch
P is the Auto Power Switch (Power/ECON)
B is +12v IGN
+B1 is +12v IGN
ACxx is usually AirCon related

L1, L2, L3, and ECT are all AutoECU related.
As for EGW, TILL, CCO, M, I am not sure.
CCO sounds like it could be the VSV output for the Charcoal Canister.
EGW may be something EGR related at a guess??
TILL could be Turbo Indicator Light or something??
M has me stumped though.

EGW - exhaust temp warning light
CCO - exhaust temp sensor
TILL - turbo light IIRC
M - no idea.

1. OX - oxygen sensor input to ecu
2. L2
3. L3
4. M-REL
5. FC - switched to earth output for circuit opening relay
6. SPD - speed sensor input
7. W - check engine light
8. THA - air intake temp sensor
9.
10. CCO - exhaust temp sensor
11. BAT - battery (permanent)
12. IGS/W - i think these are to the ignitor...
13. E2i
14. E1i
15. ECT
16. L1
17. AC
18.
19. EGW - exhaust temp warning light
20. STP
21.
22.
23. +B
24. +B1
Anything else i should know from this plug? is the SPD line the same on both cars? should i wire that?
Thanks
EDIT: My layout on the pins didn't work so it takes up heaps of room now sorry

i have wired everything but the temp and tacho. i only had one plug that the motor used to plug into the main loom. I WILL PUT MONEY ON I HAVE NO YELLOW WITH GREEN STRIPE! Anyone in the area feel free to come find it. if you do i will give you money. it definitely isn't there. failing that how does the temp sensor work. i know i have asked this elsewhere but does anyone have any ideas? is it resistance change Vs Temp?
Failing this how will i find the wire? or is it fairly hopeless?
Thanks

(I am assuming here you can't find the temp wire in the ENGINE loom)
Ok
Find the SINGLE WIRE PLUG near the thermostat.
Not either of the 2 wire ones, but the single wire one.
Unplug it, and put a multimeter on it.
Now go into glovebox plugs, and test which one it is.
Now, for the dash side of it, the MX73 uses a BLUE wire. The MA61 uses a YELLOW-GREEN like you have looked for.
You will most likely have the Y-G (I put MX73 there just incase)
Am I correct in assuming you are looking at the plug where the glove box goes?

yeah maybe i haven't explain properly. the engine loom has the yellow green. its the dash on i need. there is definitely no yellow green so maybe i will try the blue on. in that case i should be able to measure 12V's on the pin. put a variable resistor there to ground and make the gauge go up and down.
Thanks for the stuff CrUZsida. i will work it out eventually.

well i found it. and it ended up being the wire i suspected the whole time. it ended up being the BLUE wire with brown dots. thanks CrUZsida. And the wire was outputting 5V's i didn't realise how logarithmic the sensor was so i wasn't happy putting 100 ohms to ground incase i broke something. but yeah it all seems good now. yay. does anyone know if both gauges will be EXACTLY the same. (1G-GTE and 1G-GE) as i feel this gauge is running slightly cooler now, but i guess thats not a problem.

If it's anything like most Toyota ones of the same vintage it should be fine. Mine comes up to just under half way on the digital gauge and pretty much sits there the whole time, just like it did with the 1GEU.

Yeah, all guages are the same.
From about 1981 to at least 1997

your temp guage sender is simply an NTC thermister in a nice housing.
NTC = negative temperature co-efficient.
