4l80e speedo wiring

If there's any site out there that can help,it's you guys!! Im a new guy here, so if this is posted in the wrong area im sorry. I've got a 92 350/4l80e with a 16147060 ECM. I bought an aftermarket speedo and took a shot at wiring it up. My question is which wire do I hook signal to? I've got it hooked to the vssb (C15 lt blue/black) speedo signal. I looked on autometer's site and they show it hooked to the speed sensor. I checked the wires and their not shorted or broke and I have a new speed sensor. So my question is does it hook to (C12) or (C7) or do I have another problem? Thanks in advance for the replies:thumbsup:

VSSB is a buffered signal to dash speedometer, cruise control and ABS or? I think... that speedo you have wants direct VSS connection? 4l80E has TIS and TOS Input Speed and Ouput Speed too...

Check this thread for some good wiring diagrams.

yeah you probably need to figure out if your gauge needs a direct pulsed ac signal to it. If so, you'll need to tap off the speed sensor off the back of the transfercase somewhere.

is this a 2wd or 4wd?

I am tuning my own 7060' You plan on tuning yours?

I porbably have the same speedo in my Camaro, I can check and see which wire I hooked up to it.
