Mystefyer Posted May 18, 2019 Report Share Posted May 18, 2019 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 Quote Link to comment Share on other sites More sharing options...
Mystefyer Posted May 19, 2019 Author Report Share Posted May 19, 2019 Figured it out. On the G+ Link ECU the VC is the 5V+ :-) Quote Link to comment Share on other sites More sharing options...
Nathane39 Posted July 19, 2020 Report Share Posted July 19, 2020 Did you wire it to the expansion harness or the OEM harness ? Quote Link to comment Share on other sites More sharing options...
