I'm in the midst of cleaing out all the unused wiring since I've got a carb'd 13B and no emissions. Car is an 85 GSL.

Well I've started rewiring the emission harness and have got the water temp and oil temp completed, now I'm somwhat stuck on the alternator. On the back of the alternator is the female connector containg the WB/BW wires, whilst I've sorted the WB wire out and got it replaced I can't figure out the BW one.


With the loom pulled off the car and tape removed I found that the BW wire becomes many:


I'm reasonably certain that the BW wire out of the female connector is the one all the other wires are leaching off off and I think that's the only one I need.

Finally the single wire splits again and this is the bit that has me stumped.


The top BW wires is what looks like the same wire from the female connector and the bottom one leaches off of it.


Now with that outta the way, my question is which one do I need to save? Top, bottom, or are both needed? I'd assume the top one is the only one I'd need but I can't make sense of it, lol. I've got the 85 FSM open in another window and I've just gotten myself even more lost. I've searched and perhaps I'm not using the correct key words but I've yet to find anything with my wiring harness. Found Jezzus's thread but his was different. Thanks guys and gals.

Bw wire splits before going through that plug. Two Bw wires splice back together after going through that plug. I guess Mazda wanted to be sure.

Ah, so it goes back to one wire after the loom ennters the firewall? I've pulled it out as far as I ca get it but haven't found that join.

Update:

Since I've had a hard time figuring out this lil bit I decided to make up my own lil harness and see what does what. Basically I've copied what Mazda did with the stock harness but apparently I've overlooked somethings.

This is what I mocked up for the BW wire coming off the female plug. Wire with the black zip tie is the top wire in the plug:

WB wire is ran as Mazda desinged to the pin on the smaller of the two harness plugs.

As Mazda did with theirs I jumped the single wire into two with the vampire clip problem is now is it won't kill the car through the ignition switch. With the ignition switch in the OFF position: Pull the top one apart, still runs. Pull the bottom off, still runs. Disconnect both, car dies. I know I'm missing something obvious here but I've been studying the FSM for so long that I can't make since of it.



EDIT: Actually I think it just clicked. Gonna try it out and see what happens.
