anybody have any info on wiring schematics and or info regarding wire up? I can't find anything regarding what type of sensor it has. I know it's off a soarer 1jz with three wires (red, blue/red and yellow).

thank you

2 speed sensors on a supra
1 in the tach mechanical to ecu signal there.
1 in the trans for ABS(Man & Auto) & ECT computer (automatics)
The ECT can run off of one only if it looses one of them.

Soarers use 100% electronic speedos, intstead of 50/50 for the gauge (mechanical) & ecu(electrical)

You may want to switch to mechanical.

I know the SC & soarer speed gauges suck the led wires in the needles break and they light up intermittently.
Unless using the soarer digital gauge.

I'm using a haltech e11v2 stand alone. I can manipulate any signal to achieve my pulse needed to achieve speed. By wiring this in i achieve speed depedent and gear boost setting in open and closed loop and ati-lag without having to engage my clutch or any other action.

I need to know what the rear speed sensor output wires are (3 wires). yes this trans has only 100% digital out puts.

rear speed sensor wire colors are: yellow, red, blue/red and another sensor with two wires which is my reverse trigger for back up lights.

There is a difference in sensors
I am not sure of your ECU input types.
But,

3 wire sensors are HALL effect sensors
2 wire sensors are Reluctor sensors

You might need to use the two wire types?
Someone to confirm this for this ECU & tranny maybe of a better help

Hmmm.. it could be a hall that would explain the three wires. but, then again i believe the rear sensor also works as a abs output sensor and one wire could be for the abs unit. I'm guessing. but so far, your response is the best i've heard so far. Do you think a toyo dealer would know?

You will know more then them how many of them work on a soarer R154 in the US?

VRT Variable Reluctance Transducers AKA Reluctor sensors have 2 wires
One wire is ground the other is a signal wire. Generates a sign wave when the trigger passes.
In rare casses some have 3 wires if it is shielded to keep EMI out --> 1JZ CAM CRANK sensors for example have shields on them tranny sensors usually wont.

Digital Hall Effect & Optical Sensor are different all together.
Because they need a power supply to generate a signal
These sensors always have 3 or more wires in rare cases 4 or more depending on additional grounds and shielding.
The three wire minimum is because,
One wire is ground the other is VCC positive supply and one is a signal output.

What I recommend is get your car running first.
The while your car is moving or on a dyno tap the signal with a meter & scope
you will find a steady 5 or 12 volt DC for sure with the meter on a hall effect and you could get your reading per mph from the sensor output to set up with your ECU like pulse with sign wave rpm per mph etc and set up the selectivity and sensitivity.

Hey I found the answer
It is hall effect or optic sensor..
It is speed sensor #1
Yellow wire is +12 VDC (goes to 10A Gauge fuse)
Red wire is ground (goes to gauge cluster ground)
Blue/Red is the digital pulse output (goes to speedo, ect, cruise, PPS, AC Amp etc this is the wire you use to drive you hal tech ecu however be warned you may need the gauge cluster because the odometer reads the blue/red wire signal and at the odemeter chip produces a pink wire output that goes to ecu etc so you may need the odometer from a soarer or mkiv supra to amplify the blue red signal so your ecu can read it form the pink wire output.

All this is found from the cuzin MKIV schematic which haves the same layout speed sensing circuit and you can find the mkiv schematic all day long!

wow, Amazing. You drilled that question down. thank you very much. It seems like you made it a mission. Again, very thankful for all your help. Happy holidays.

I'll let you know in about a week or so the outcome. I'm currently returning my e11v2 and switching for a haltech p2000.

im actually having a bit of the same problem. I got the Marlin crawler cable to electric speedo senor.. any ways its three wires also.. i wired it up and it dosent work.. i wired yellow to 12v key on, blue/red to my AEM v2 ems and speedo imput for the cluster (240sx), and red to a ecu ground? should i change the yellow to 5v senor reference? sorry to tread jack a bit but its on the same topic

According with MKIV TRSM if you look at the cluster
yellow is +12vdc
red is instrument cluster ground
blue/red goes to the odometer chip where it will read the speed sensor signal then convert it to an output the normal computers read at the pink wire this goes to ABS ECT ECU PPS Cruise control, etc...

At the blue/red I dont know how many pulses per mph it generates or the peak to peak voltage if it is digital square wave saw tooth milli volts sign wave ? etc.. so it is unlikely that most ecu's will be able to read the blue/red but the pink wire that comes out of the odometer chip the gauge cluster will most likely put out a clean 0-5VDC square wave any ecu can read for sure.

You will have to grab an Oscope and measure the signals to try and get your ecus to read them and check with your mfg. to see what the selectivity or sensativity would be needed to read these signal wires if not wire only the odometer chip and get it off the pink wire output.

norcaldrifter keep me posted on your outcome. I'm doing a 240sx too. I'm running a haltech sport 2000. What i've read it's able to manipulate any signal from 0 to 50,000 hrts, so i should see mph but i won't know until i get it on the dyno and start plugging numbers in.
