Mitsubishi Pajero Mini Junior AISIN MR195407 MR195408 and MR246350 Daihatsu 89530-87507 Transmission Control Unit Pinouts, There may be others but these are the ones I see often.<\/p>\n

This Page May be a mess till fully updated<\/strong>..<\/p>\n

This is a Work in Progress, If anyone has the missing information let me know. (Do you need Your Pajero TCU Serviced Click Here For Info<\/a>)<\/p>\n

Need to do,
\nSolenoid Activation Per Gear?
\nEngine Pulse Type Magnetic, Hall, other.\u00a0 Info for Shift Points and Pulse Data.
\nSpeed Pulse Info For Shift Points Is Sensor Inductive or Hall Effect?
\nFigure out Pin 12<\/p>\n
