grrrr...1jz tach issue...
I seem to be running into every unknown problem out there....
97 SC300 w/ 1JZ swap. at the point to wire up the tach properly, only thing is that resistor R109 does not exist on my circuit board. Yes i've searched around and yes i've seen the video, and everyone's is different from my tach. The only resistor that resembles R109 is resistor R2. Can anyone confirm a tach fix for the 97+ SCs?

So...here I go
Have 94 SC300 with 1jz swap
same problem tach does not work,
I saw the video, but I dont have r109 in that place, I have it elsewhere,
Also did not find R2 resistor.
Any ideas?

As you can see there is no R109 resistor in needed place.

you need to jump R73 thats above the center connector. my 95 board matches the part number on yours. They must have started using the new PCB boards at the end of 94
here you can see the matching part number
you can see the jumpered R73 above the center connector
a closer pic of the jumpered R73
