found something in the service manual,
How about the Injector no.1 Pin 23 r/b
DC voltage is 11-14V Pulse cycle signal
The raptor shift light can run from 1,2,3,4,6,8,10,12 cylinders

Its about halfway down the page (GReddy e-manage RPM Signal Extraction Adapter #1). I am not completely positive it will work, but I think it is at least worth the try.

I did some research in the service manual, And found that the crankshaft position sensor runs 1.4V signal, and the coil pack signal is 0.1-0.4V
The shift light unit runs 5 or 12 volt tach signal operation (ECM or coil)
I found that the Injectors battery voltage is 11-14V and pulse cycle like the coil pack. Would this work instead of the Coil pack signal wire?

The crank shaft wire is 0 - 12vdc, you are reading your service manual wrong. If you look up by the 1.4v or whatever you will see there is a star, that star means that the voltage listed is the AVERAGE voltage, not the peak voltage. If you look at the o'scope screen you can see that the signal is in fact a 12vdc square wave.
My shift light is hooked up to my crank angel wire (actually, the shielded crank angle wire from my APS TT) and it works fine.
My shift light used to be hooked up to my fuel injector signal and that worked well too. You shouldn't need a tach adapter of any kind. ALL the signals in the Z are at least 5vdc peak.
I would try a fuel injector if the crank angle didn't work. I'm not sure if I would go with the ignition wire, as I have never scoped it, and they tend to be kinda noisey (in other cars that I have scoped)

out of curiousity, why in the world does the Z not have a tach signal and where is the Tach in the cockpit getting it's signal from then???? Why can't one simply splice into that?

CAN bus owns all.....
The Z does have a tach signal, its called the crank angle sensor. This wire is read by the ECU and sent to the cluster via CAN I believe (I would have to doublecheck). The crank angle signal pulses x amount of times per second based on how fast the crankshaft is spinning.
Since the Z doesn't have a distributor or any shared coils the amount of tach signals is less then most cars. Despite missing a distributor, the Z still has the crank angle, the cam angles, the fuel injectors, and individual coils wires. Thats a total of 15 wires that should all be usable for a tach or a shift light.

Im going to try the fuel injector since the other ones did not work. I also emailed Raptor perfromance, part of the service manual and came up with fuel injector as well. The raptor needs a min 5v signal to 12v to work.
Ill have to wait tell the weekend to do this again, but will keep you all informed.

The fuel injector signal is identical to the crank angle, but the frequency is MUCH lower. Maybe the raptor will work better with a slower signal, but its strange to me that it won't work with the crank angle...

Ok guys, for those who have the Raptor shift light, you will want to use the Fuel Injector signal No.1 at Pin23 Red/Black wire. I connected it lastnight and it works.
I tried the crank angle, coil pack signal wires and they did not work. It was an easy install. Ill take pictures tonight to show were i mounted it. I mounted it on the display housing on the upper left side were the fuel gauge is. Used 3M double sided tape and is holding up.
Im happy now that it works.

what are your setting on the raptior shift light. ive hooked it up to the pin 23 fuel injector on the ecu but the light doesnt work!! i hooked up my volt meter. while warming up the wire output 14.xx it fluctuated constantly! This i think is fine so what could be my problem?

I just installed the Raptor shift light. I hooked up the tach to the tach signal on my racelogic traction control since it was easier to reach than going to the ecu (it' s connected to the negative side of a coil) but no go...
I guess Injector 1 is my next try.
What is the cyl1nder setting that you set it to 1 or 6?

ok, this is getting really frustrating.
I went to the ecu and first of all this makes me miss my celica...it was sooo easy to find pins and splice into them due to the easy location on the celi...
What a mess...I got the harness disconnected and there is no Red/Black wire...I did find the wire going into pin 23 which is white....actually a vast majority of the wires are white.
I spliced into that but no luck getting the raptor light to react.
I changed the cylinder setting to 1 and set the shift light to come on at 3500 rpm to test but nada...
I hooked up a volt meter and since I was alone I couldn't try while hitting the throttle but I got a 0.15 volts on idle...not sure if that is accurate or not.
I had bought the greddy can tach adapter when brainstorm had troubl
Anyone have any thoughts?
Could I maybe have a bad raptor light?
is the .15 volt correct at idle ?
Is it possible that the 05 has a different voltage output?
