OK. So I'm getting ready to purchase these. I plan on replacing the stock gauge with the DM-100. I'm just wondering if I'll have to purchase the PLX Vac/Boost sensor or if I'll be able to somehow connect to the already existing line that's connected to the stock gauge. I don't know if that makes sense. Anyways, if anyone could help me out.

 

Ur stock guage is ran off ur ecm isnt it?
If so u might have to get the sensor

 

See that's what I thought, but then I thought I read somewhere that the DM-100 can read peripherals from your ECM.
