Has anyone Ls swapped their digital dash cars and had the digital dash still work with the swap. Everything I'm searching on the internet makes it sound like a wiring nightmare to try and keep it working if you Ls swap it. I got a great deal on a 6.0 lq4 engine but don't want a dead dash board just to use the 6.0. Might have to stick with the TPI because of this ,anyone have any insight into this?

 

Gauges aren't some magical thing that needs the factory ECM to make work. The factory digital gauges are largely the same as the analog gauges. There is no "wiring nightmare", it the same as analog gauges. Get a FSM for your year and start doing your homework
Speedo is easy if it doesn't work, Dakota digital has the answer. If the tach doesn't work, Dakota digital has the answer. That leaves the temp and oil pressure, bot are easily worked with some thread adapters.
