Awesome! I was looking at the SGI-8 as well... will get 'em both and I'll play with it.
By the way, would you consider rearranging your cluster like 2 big ones on the center and the small ones besides it... like typical Lexus/BMW cluster.. just a thought.
Appreciate your inputs guys

If your keeping your stock engine, you wont need the SGI-8. Only reason I had the SGI-8 was to translate tach signal from the LS1's 4-cyl output signal to something the stock 2JZ toyota cluster would read.
And I had originally planned to have the tach and speedo centered, but I liked having the tach in center to keep an eye on rpm's and the shift lights at the track.

Jeslet, I think Ali is saying that you can use an r154 cable sender, and then get the marlin crawler cable to electronic adapter. The problem is, both the cable, and the electronic w58/r154 type speed sensors rely on a gear to drive them. I'm not sure of a good way around this, so it seems like signal conversion is the only option.

yeah I dont think you can just plug up the 2 wire sensor to 2 of the 3 wires on the 3 wire. different signals wont trigger right. the sine wave goes both positive and neg voltage, the square wave on the 3 wire will just go from zero to postive is why you need a converter. if it does trigger it will be erratic to say the least.
Stockhatch is right in what I was saying, but I think he is right it wont work because those have a gear on the end, I guess the other ones don't? I haven't seen the solstice one but I thought most the toyota ones have the gear at the end. converter box should work no problem once it is wired up it will convert the sine wave to a square wave.

R514 has gears hence "speedometer driven gear". I guess the Dakota Digital will solve this as what turbodremz have explained.

And just to clarify I need to take the R109 completely off of the cuircuit board, correct?

Here's my 1997 VSS wiring on my wiring manual.
First, I connected RED (ground) and BLUE/RED (out) onto the 2 wires of the GM speed sensor and left the YELLOW wire capped. Speedometer is pulsing or jumping and there is some kind of interference when I click my turn blinkers... looks hilarious, like an analog stereo needle.
Then, I wired YELLOW AND BLUE/RED onto the GM speed sensor and grounded the RED wire on the chassis and no signal/movement at all.
Lastly, I joined RED and YELLOW on to one of the GM speed sensor wire and BLUE/RED onto another and it shorted my whole cluster, no lights at all. Good thing I found the 10A fuse on the driver side kick panel.
Continuation of the 3 wires on the next page...

Sorry for high jacking the tread but I have a question related to the diagram posted.
I was always told that the SC400/SC300 used VSS– ECM-Cluster and the supra was VSS–Cluster-ECM
The main reason I am asking, I was troubleshooting a speed sensor issue while doing a manual conversion in a SC400 a while back and I was told feeding the Hall Effect signal straight to the dash wouldn’t work. My original idea was to feed a signal wire directly into the cluster bypassing the ECM but I was told otherwise.
The diagram contradicts that info. Are those picture from a supra service manual or a SC?

Good question, this thread may have some info.
https://www.clublexus.com/forums/per...sors-help.html
seems like manuals have 1 and not sure the order. seems like auto harnesses have 2 and they are seperate one to ecu, one to meter. so if it is a sc400 it probably has wiring going seperate to both places.
they are saying 3 wire goes to combination meter and 2 wire goes to ecu, so you could do the hall effect to the wiring to the combination meter, and leave the ecu one disconnected. probably no speed cut as well.
what year SC did they put the wheel speed sensors on. maybe you guys can just get one of those install it and run the wires and call it a day instead of using the converter box. wont be a way to adjust for gearing though is main shortside I think.

Hey guys... i took out my 1997 cluster to find the R109 but i couldn't find it. However, i found the same looking resistor called R2.
Here is the R109 on the pre 97 SC cluster:
http://www.supraforums.com/forum/sho...-R109-Resistor
And here's mine and it says R2... maybe this is the one?
And this is the overall pic of the 1997 cluster
