ok if anybody is still watching this I am down to one wire. its the yel/wht wire the starts at the coolant temp sensor on the 2001 and runs to my temp gauge. The 04 it starts at the computer and runs to the temp gauge and isn't even hooked up at the sensor. the 01 computer doesn't have the pin out for it. any suggestions?

BTW this thing goes like hell with the 2.7!!!!
05 ECM C51-3 2 (ORN/BLK) goes to Engine Coolant Temp sensor.  The GRY/YEL wire from ECT goes to a splice with other computer grnding wires and connects to C51-3 25.

ECM E61 25 YEL/WHT goes to Auto AC controller G52 26 and Dash CPU G11 5

So ECT sensor goes to ECM C51-3 2 ORN/BLK  then your YEL/WHT wire from ECM E61 25 goes to Dash CPU plug G11 5

Good to hear that it is running (even with minor issues.

Why not just run the 01 cluster?  The temp gauge is analog and the voltage will vary with the temperature.

i might end up scrounging a ecu from a 2.7l that ran the same instrument cluster or just ignore it and install an aftermarket.

I'm using the 01 ecu, the 01 sensor, and the 04 instrument cluster the temp on the cluster was controlled by  C51-3-19 YEL/WHT ECT sensor signal for combination
meter. the 01 temp gauge in the cluster  ran directly off the off the center wire on the (yel/wht) i will check what the voltage is off the sensor and post that. but i know its not pulsed.
04 ecu output of c51-3-19 (the * means its a pulse) (see fsm 99500-65d20-01e page 6-1-47 for 04.)
✱0 – 0.6 V
↑↓
4 – 6 V
(Repeated
indicator)
Ignition switch turned ON
(Output signal is 1 Hz active low duty
pulse. Duty ratio varies depending on
ECT.)
ECT 40°C = 45% ON duty
ECT 120°C = 85% ON duty

Are you running the '01 cluster with the '04 ECU?  Do you have the '04 cluster?

I'm not familiar with the '04 but on the '01 the temp sensor is a dual sensor - it has two separate sections, one for the gauge and one for the ECU - one possible option is to use the '01 sensor as designed.

Almost there! actually got to take it for a drive today! I'm still having some issues with the shift lock and some of the a/c wiring. but running good only one code (po450)
I got back from the test drive and my blinkers stopped working along with my backup lights and auto daytime running lights. oh well back to the diagrams lol

3xl7sofar, thanks for the reply.  I went back to the shop that had the 2.7 deal, but after running a carfax on the vin it appears the 2.7 has at least 200k miles, so I'm back to doing a timing chain kit on my 2.5.  I'll be watching here to see how the swap turns out.

hey tortis I'm still working on mine it is a huge amount of study to figure out what wires do what and go where as it seems suzuki changed the pinout of there ecu almost every model
and even the fsm doesn't  cover all the wires you may find (i still have 3 unidentified) as for the long block swap the 2.5 intake manifold would need to be changed over to the new block along with any other manifolds and sensors that don't match. I will post my results and all changes I made when I am done with my swap.

I've been following this thread very closely, as I have a 99 GV with very noisy chains.

After investing a lot of time and money into modifications, I've decided to fix the noisy timing chain.  I recently witnessed the tear down of a 2.5 that had granuals of chain guides throughout the block and heads, requiring a total overhaul.

Two days ago, I was at a local shop that had a wrecked 2.7 GV 4x4 sitting out back that they are making me a great deal on.  I was able to start it up and the engine is very quiet.  I have to go back and get the vin# to get more serious about the possibilities of a swap.  After reading this thread and the 2005 thread from stuntpilot, I have a few questions: 

Does anyone on this forum have first hand experience performing the "long block swap" (option 1) that Eric mentioned?
If so, what did they do for the MAF sensor?  (change intake? or, rewire new MAF sensor? 
Any other mods required to do this option?

Currently am leaning towards doing the wiring changes (option 3), since I have a running donor vehicle that is 4x4 with all the wiring, but I don't want to dive in and find it is too fiddly.  Any info would be appreciated very much.

Thanks!

YES!!! thank you FordEM that was my missing puzzle piece I now have the relevant diagrams for the 2001 and the 2003/4. I will start reviewing the tonight (like thats not what I've been doing all week) As far as I can tell I just have to figure out the 2 plug e-61 and c-52 and I'm good to go. thank guys I will keep you posted

i have almost all the suzuki fsm 1998-2006 but it seems i am missing the wiring manual for the dec. 2003 (should i just call it a 2004?) the number i have for it is 99512-52D10-015 anyone have it? I'm going to web search for it tonight but don't hold out much hope. this is the last piece of the puzzle and i can start moving pins
In case any of you have a diagram that matches
my pin outs for the 12/2003 2004? c-52 are as follows
1. -
2. blu/yel
3. blu
4. lt blu
5. grn
6. yel/grn
7. orn/blu
8. orn/grn
9. orn/grn
10. blk
11. blu/blk
12. red
13. orn/blk
14. red
15. pnk
16. blk/red
17. -
18. grn/orn
19. blk/yel
20. blk/red
21. yel/wht

update i have the diagrams for e-61 for both the 2001 and the 2003. i have the diagrams for the 2001 that show the wires for c-52.  I can't seem to find the diagrams that match the 12/2003 for c-52 getting very close im 5 wires away on c-52  most of the wire colors match. but id like to read the diagrams to make sure the same colors do the same thing

thanks for the diagrams they are close to the 2001 2.7l i found the diagram for the 2003 2.5 for e-61 going through the fsm trying to figure out c-52
the problem is the 01/2001 2.7 js3tx92v1141xxxx3 I cant figure out which fsm it is. the vin lookup in the manuals starts at js3tx92v-2xxxxxxxxx I think I have all the fsm manuals from 1998 to 2006. BTW im in western washington
