vss wiring 4l80
Ok, I just completed my build and the only thing that doesn't work( with the exception of nss and reverse lights) Is the speedo.
I'm using a fast ez tcu, everything on the controller is reading and working fine so far! i have the speedo output wired into the ecm ( pin 71 vss high side, gray with black stripe) does it get wired into the ecm or does it get wired as if the signal is coming out of the ecm? I have it wired the latter of the two ways.

not being familiar with the fast setup I know that most setups have to go through the ecu to convert the signal. With my harness from Pcmofnc it only reads one sensor and taps into the main ecu which gives speedo reading. Do you have a link or can show how they want to route everything so I can see what they reccomend?

There is the link for the instructions. I'm guessing I will have to wire it going into the ecm... I'll try this and report back! Aside from that everything works great on it! Will have more info on it after my tune

Ok so the speedo now works, go figure I had it wired right the first time....
It gets wired going INTO the ecm on pin 71. The issue was my wheel speed wasn't up high enough to read.
