Looks like I'm going with US Shift controller and harness. They make a TPS adapter to split and isolate the TPS signal from the Holley Sniper. Then I've got to buy a Speedhut "speedbox" to provide a signal to my cable-driven speedometer. A lot of $$$. But if I had done this 3 700r4's ago it would have saved me money, and a lot of aggravation.

I have a 1990 V2500 Suburban and I am running the US Shift for my 4L80E. I am using the sensor on the transfer case for my speed input. I have an electronic speedometer in my suburban.
I have over 75,000 miles using this controller and it has been great.
