My J&S is identical to this one
For your info, my JR EMS is grounded to one of the ECU monting bolt (per JR instructions if I remember correctly). I cut the cigarette lighter 12V supply and ground wires and I'm using those for the J&S, my J&S audible alarm and my APEX'i a/f ratio meter (auto meter). My JR EMS is also using this 12V power supply.
Deep switches are as follow, 1-up, 2-up, 3-up, 4-up, 5 down.
Only switches #1 (up=20deg, down=10deg, max) & #2 (up=retard all, down=retard individual) can be set up or down. Since I want maximum protection and don't care about loosing power (not racing), both are up.
Switches 3, 4 and 5 must be as mentionned (for hondas) per J&S instructions.
