Hi All, I hope someone can clarify something for me. I have a full kit ready to be built in my 91 St185, but have some confusion about connecting the Link 4 Bar map sensor. I think I should swap it with the factory one but... the factory has 2 sensor outputs and a ground (Brown) input, 1 sensor wire goes to ECU PIM pin & Boost Gauge in dash (Red-White), the other to ECU VC pin & AFM and Throttle sensor (Pink-Blue). The explanations for VC and PIM are pretty much the same: - VC: Turbo charging pressure sensor signal - PIM: Signal from the turbo sensor, also drives the boost gauge So if I can replace directly, is the VC the +5V? Or do I disconnect the factory MAP and need the expansion loom to make this work? Hop someone can clear my confusion :s With kind regards, Mystefyer
