MS2 Brown Wire

[STOICH]

Need a refresher please:

I am swapping my MS2 from my old sandrail back to a baja bug. I have found a Brown wire that I had cut short, about the same length as the wires for the fuel pump, and 12V wires that were going to relays. According to the MS2 wire schematic, it shows a brown wire, however, it doesn't really list a function, am I reading that correctly that it runs through a 3 amp fuse and simply to a switched 12V? The wire itself has either lost any written labeling over the years or never had it- I say that as the MS2 diagram doesn't have it labeled either, or at least not that I can see. Without the wire being labeled, and my being used to Brown being ground, I figured I'd run for help first, rather than last. Thanks for the help!

Sorry If that is considered a dumb question, I'm finding a few different schematics that contradict each other. I'm starting to wonder if that was possibly my signal wire to the MSD. Well, I'll keep at it.

There are no dumb questions! In this case its just that some times additional understanding(s) needs to be clarified.

It looks to be a power point off the battery, through a couple of relays, that hooks into a distribution point but prior to that a tap for a hall sensor can be made... if necessary. That's my reading of the wiring diagram anyway... for what it is worth.

I appreciate that Lee I've let the smoke out of this thing before, and the kind people at DIYautotune were nice enough to save me that time- I'm a little gunshy on it now. I know it is a MS2, but the wiring from the MS3 schematic is more how I remember it- I think it was firing the MSD. That came to me this morning however, maybe it will make more sense when I am looking at it again.

It does look like a 3 amp circuit breaker so as the old saying goes: if the foo $#its wear it . Double check things first though.

Solved. thanks, you haven't heard the last of me!
