Re: factory boost gauge wiring??

About 12 inches up from where the factory ECU is, there's a 10 pin plug referred to as C101. This is probably where you cut in your tach wiring.

In that plug there's a green circuit that goes to the boost gauge. It's a 0-5v gauge.

What map sensor does the LS use? A 12v ref or 5v ref?
