Yes, trying to track down how/what/where/why the "start module" did is what spawned my "egad!" comment. I still haven't figured it out (ok, ok... nor wasted more time on it).

I'll look into "does fuse 6 subsequently power fuse XX?" ... that's in the "power distribution" section of 8W. ... i'm going to guess that it doesn't ... they normally don't cascade small fuses.
(?? by "next to it", do you mean in the diagram, or in the fuse box??)
The diagram's Fuse 9 (on the left) is from "always powered", whereas Fuse 6 is powered from the ignition switch. Those are not cascaded.

I think i figured out the "meaning" of those "sideways arrows to nowhere" ...

They mean that that Fuse in Block 1 (FB1) connects via internal copper bars (or wires) to other components that are also a part of FB1.

Here's page 8w-10-21 ... where the "bottom" of fuse 6 connects to the wiper system and also (via pin2 on C3) off-board:

8w-10-21-Fuse-6.png

Fuse 9 is totally separate from Fuse 6 ... the feed into Fuse 6 comes from the ignition switch.

I came to basically the same conclusion, but that doesn't help the fact that they aren't at all labelled, and that where the arrows go does matter when attempting to follow/troubleshoot using the schematics.

Another revelation for those who haven't figured it out.

The "Wiper/Turn Signal/Engine Start Control Module" label isn't a specific reference.

Wiper/Turn Signal/Engine Start Control Module = Fuse Box #1 aka FB#1.
The FB#1 module includes all of those functions listed.

The power from Fuse #6 is just one of the power feeds within the module. The power inputs don't all necessarily relate to starting or ALL functions. Some are specific to one of the sections/circuits.

Then again. I'm also still learning so FWIW.

OK, I think i understand what was happening. My hazard/flashers/e-lights switch would turn on the turnsignals, when I had fuse 6 pulled, because the blinkers are are powered through 9, and able to be activate by the hazard light switch independently. Normally however, they are activated by the multi fuction switch when the ignition is keyed on, through fuse 6 (even though this is called wipers, only). I think.

My confusion arose when my turn signals operated with the hazard lights switch activated but not the turn signal when fuse 6 was removed. If Im not mistaken above, this makes sense now.
