MLA Module Help

[CaddieJapan 10+ year member]

I just purchased the MLA module for a Toyota vehicle. Question I have is regarding installation. Vehicle uses a Toyota Denso Alt with 4 pin connector. The pins are IGN (ignition), S Load Sensing (goes to voltage regulator in the alternator), L for lamp indicator, and FR which goes to the vehicle ECU. Which line do I need to tap into for this to work? Any info would certainly help, thanks all.
