Sam Posted October 15, 2018 Share Posted October 15, 2018 Don’t know wiring pin out, but you can probably find the wiring diagrams and figure it out. Otherwise there are a few people that are making kits which are plug and play. PCM will be looking for a 0-5v signal I believe. Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted October 15, 2018 Share Posted October 15, 2018 We have 3 writeups depending on what you want to know about. Pinout is in the dual map discussion thread. Voltage is 0-1.66v however some late model FGs accept up to 3.8v You can use a voltage divider (two resistors) to step the voltage down from 5v to 1.66v Quote Link to comment Share on other sites More sharing options...
