Just wanted to make sure I know what I'm doing so I thought I would ask for clarification on two topics. 1.) I believe I just tee into C2 pin 25 lt. grn, map sensor signal for the input for a future sunbird turbo tach installation? is that correct? I assume its a voltage signal which goes to ground via the turbo gauge? is that also correct? 2.) What is the typical source of +12v when wiring in the VSS interface circuit on a 3800SC swap. I am probably going to install near C203 and I believe I should use pin F ( ECM fused). Is that correct? if not what do people with experience recommend. Curtis
