Wiring Specs for Push Button Ignition Switch?

SEC-126 shows pin 4 of connector M50 is for the start switch contact and pins 5-7 are for the ON/ACC/LOCK lights. As far as I can tell pins 2 and 3 are not connected. Pins 1 is ground. Pin 8 is battery power from fuse #9 (10A) in the Fuse Block (J/B).

If you just need a signal, you should be able to use pin 6 for ACC and pin 7 for ON (see pinout on page SEC-132 for colors), but they weren't designed to power anything. If you need ACC/ON power, I still think you should get it from the Fuse Block (J/B).

Are you sure the HKS unit will work with pushbutton ignition? The description for the harnesses for that unit says they won't work with pb ignition - maybe that's just the harnesses.
