After reading zunny's posts I agree with you @pwuser153247015751 . There are two things unclear here for new learners:
The brake switch #3 where in the MICU/Fusebox to connect? As far as i know it is Ignition switched battery voltage only, Im not sure what that "yelllow wire near the red wire" is for. But yes, please clarify if we tap on yellow wire (i think Connector E #28 is it?)
WHAT SIZE pins and HOW to remove dust cap to INSERT into ECU/PCM connector A 39 (and/or 41)? There seem to be rubbers there on the pin holes--i checked and confirmed that we should remove them)
Moreover, where can you source the pins @zunny? I had a hard time inserting similar (but not the same) pins. Hope it works. Still waiting for the 4 pin brake switch.
Thanks.
