well picked up a cluster at a probably stolen price and it came with the housing and buttons and even the pigtail for the harness... so begins the conversion from 05-06 G35 to 07+ G37

12/21/2010 - got the 08 G37 cluster in and pined it out. got power to it only to realize it was going to be more work than I planned on. it seems they off loaded the unified meter and a/c amp to a separate unit. It used to reside partially on the gauge cluster and in the ac/compass display.

12/22/2010 - found the unified meter and a/c amp so I ordered it, waiting for it to come in so I can get more done. In the mean time I worked on mapping out the wires. It seems I'll be pulling wires from the 2006 ac/compass display, and the existing cluster harness to go to both the new cluster and the new unified meter and amp, and from there back to the cluster. I just hope there isn't any other surprise computers in the way of my conversion.

12/23/2010 - spare 05 cluster came in, I'll probably end up using it for parts for the conversion. the bases are completely different so mounting will be an issue, but that was expected.

12/24/2010 - damn the unified meter came in today so I went to work quick... I furiously (but carefully) tore it apart, pin'd it out and wired it up. IT WORKS! now I just hope the meter knows how to read all the signals from the sensors in my car but besides that it should be cake.

01/01/2011 - Spent around 6 hours building a wiring harness from parts of the extra 05 cluster and the pigtail from the 08 cluster and the 08 unified meter. it's a mess, probably soldered/spliced/cut/heat shrinked 70 wires. Not to mention all the time I spent mapping out the wires from the service manuals. It was long and frustrating and it made me realize that not everything matched up perfectly like I had hoped.

01/02/2011 - did some more work on the adapter harness and I figured I should go try it to see if any of it functions.
Good News:
- It powers up, corresponds correctly with the key as far as power, accessory, ignition, and start.
- It shows fuel level and 'miles to go on tank'
- the lcd shows which door is open, and when the trunk is open with the image of the car (pretty cool)
- R/L Blinkers work, also shows high beams

Couldn't check:
- Tachometer
- Speedometer
- Temp
- Manual Mode

Bad News:
- Car doesn't start, I'm thinking its because of the Start Relay wire I wasn't able to pair up with anything on the new cluster, It tells the car it can start if it's in P or N, and not anything else, including open circuit.
- Can't find matches for 4 other wires, don't know how important they are (security and passenger seatbelt on new cluster) (start relay, stop lamp, neutral ECM on old cluster)
- Slip, VDC, ABS, Brake lights are all on, I can't find a place to put those wires on the new cluster

01/9/2011 - Spent another 4 hours today, tracing out circuits... no dice.

still can't start the car, I did find a couple more pins that match but I fear that the CAN communication of the older G35 parts (ECM, TCM, ABS) are not communicating with the G37 parts (Cluster and Unified meter)

head hurts, I'm gonna chill for a bit and think this through. I'm hitting a wall and its pissing me off.

Got it to power up!


started messing with colors


got the 05 cluster in so I powered it up too.


now it shows mileage till empty


and it keeps time!


the mess thus far...

 

Oh snap!
Gl with it
Sub'd

 

Lookin forward to see how this project comes along.

 

Oh hellz yeah man!

Do your thang kid!! I can't wait to see this!

 

sick

 

speechless. envy.

 

wow.... I'm definitely interested in this!!!

 

Just went from six to midnight.

 

wow man, This will be so freaking **** if you get it working.

 

This is gonna be crazy sick if you get it to work. Subscribed!

 

Oh man

I want!!

 

That is going to look sick if it works out, goodluck.

 

POST PROGRESS PICS!

how much did you pay?

 

aweesoome, really the only thing I dislike about the G is all the orange lights, reminds me of an old bmw, yuck.
