OK, given:
(1) I'm tired and brain-fried after too many hours awake (& not enough asleep)... AND
(2) 98+ Wiring Diagram and
(3) I need to tap the signal from speed sensor (tranny output shaft pulse generator)... AND
(4) And it has three wires going to it -- black/white, orange/red, and pink... AND
(5) And I need to leech that pulse signal for my chain oiler to compute when to pump another drop out...
Now I know I need to tap either the pink or the orange/red wire, but I can't tell which. Anyone know?
PS - for the electro-tech-heads here, the OEM test procedure for the speed sensor might clue you in (but it didn't clarify it enough for my sleep addled brain):
Given the speed sensor, put a 10k Ohm resistor inline on the pink wire, then check the voltage on each side of the resistor to test the device -- if working correctly, it should pulse 0 to 12 volts (or whatever the battery voltage is) and back to zero each time it gets a hall-effect sense (i.e. - each time metal passes through the magnetic field of the sensor).
I'm guessing orange/red is the power feed to it, with black/white the common ground (because black/wire shows a common ground with the blinkers on the wiring diagram), leaving pink as the signal coming back -- but I might be backwards on those two. Either way, if I can't find an answer here, I guess I'll know tomorrow when I latch on a multimeter and see if orange/red is continuously hot... But maybe someone could save me the effort, and I'd be greatful.
I'm off to bed & maybe sleep if I'm lucky...
