Attempting the Swap from 03-05 to 06-09</b>
**Update 7/5/2021** After taking out the 2007 cluster out of my car and putting in original, I started the car and idle was extremely low, under 500rpm for a cold start. Went for a drive to mechanic for other reasons and car stalled out twice when I came to a stop. Most likely some of the pins shorted something but since then the car has been running fine.
Alright Everybody, the moment we've been waiting for. Received the Cluster in the mail today and got right to it.

First thing I did was compare the two Clusters together to see any visual differences. The 2004 cluster has a different faceplate I put on from an SR5 but the internals are all 2004.

Nothing noticeable until I took off the rear cover and saw all of the on board electronics on the rear of the 2007 motherboard. housings are very similar, White shroud has a different clip on the side that is not seen because it was broken off upon removal from the junkyard I assume.
I decided to take them apart further to see visual differences. It seems with the mid generation upgrade they switched all of the main components from being on the same side as the LED's to the reverse side. This was most likely to allow easier LED swaps for the 4runner enthusiasts obviously XD.

So after visual inspection, I went into my 04' and tried installing it. I took a video to show the result. The mileage would need to be changed which is an easy process but that is the least of the problems

I took note of all of the differences such as indicators not working etc and this is what I found (note all of the functions still work, however the light indicators malfunction or do not work):
- Cruise Control Light Works
- DAC Light Does NOT Work
- Headlight/Fog light/High Beams Do NOT Work
- Turn Signals in Cluster Do NOT Work, However work in 04' Shroud still
- E-Brake Light is on when E-Brake is not engaged, does not change if I Engage E-Brake
- MAINT Light On, even with Car Running
- 4WD High/Lo Light Works
- Seat Belt Indicator Does NOT Work
I wanted to make sure there were no faults with the cluster and that everything was working right so I tried it on my fathers 2006 SR5 4Runner to see any discrepancies

This can all be explained pretty easily. I took the clusters apart further to compare the faceplates and it started to make sense. As i stated earlier the face plate on my 2004 extra cluster isn't a sport edition but it will work for the comparison.

Every Light Indicator that is having an issue was relocated from the 03-05 models to a new location on the 06-09 models. See Below:
- Cruise Control Light Located in the same spot
- DAC Light Has a different location, not pictured
- Headlight/Fog light/High Beams relocated from Left Side to Right Side
- Turn Signals Obvious because the wiring is external to the shroud on 03-05
- E-Brake Light relocated from Right Side to Left Side
- MAINT relocated down about an Inch on Left Side
- 4WD High/Lo Light In same location
- Seat Belt Indicator relocated down to bottom of Left Side
The Turn signals are self explanatory as they are wired into a separate connection on the 03-05 models. The connection has 5 wires, and it goes to the turn signals as well as the ODO/TRIP & RESET buttons which were relocated to inside the 06-09 cluster. 3 Wires go to the ODO/TRIP & RESET buttons one of which is a ground shared by the Turn signals. I'm fairly sure these 2 wires (3 minus the ground wire), can be ignored because of the upgrade to have those buttons integrated into the 06-09 cluster, everything seemed to work fine.
The other two wires are two positive wires, one going to left signal and the other to the right signal and they share a ground, to be able to find which pin triggers that if I wanted to do a swap would be a guessing game but I'm sure would be possible.
I also took pictures of the connections with the cluster out to see if i could spot any differences. The only noticeable difference was the wire on the 04 model for the ODO/TRIP & RESET & Turn Signals

I'm fairly certain some of the pins are left blank in the 04 and are filled in on the 06 wiring, making this actually seem possible. All that would be needed is to switch the wires accordingly based off color and see. But of course, I could be wrong. It would be more logical to see if the wires could be switched in the connectors than to solder cables on the board and jump connections to make it work. My goal is to make this mod possible for everyone not just those who are skilled in soldering.
Please let me know if anyone has any more findings, this is as far as I am going for this week as I will be out of town and don't have the time to look at the connections more closely, but this is not the end for this project.
PS: I believe the cluster I received is faulty as the MAINT and Low Tire pressure indicators are on when I tested it on the 2006 4Runner and they were not on with the original cluster. Updated electronics could also make it so the cluster can carry codes now on the board and they would have to be cleared, I will continue to look into it.
