Nope. The lower hose. Just like the factory does.
And you basically have to put the switch in for the time being, unless you're going to play sparky mcsparkler, and hot plug and unplug a jumper each and every time you shut the car down.
Might as well just splice a switch in the jumper wire, it's like 3minutes more labor and gonna make your life way better for the duration of this hack. Having the switch there will make the ghetto job of popping the hood every time you need to get on the road a lot easier vs fiddling w jumpers sometimes in the dark and possibly in the rain. Just get a couple crimp spades connectors to fit your relay connectors, some electrical tape, and a quality switch, can probably find a place to just zip tie it in place for now.
Be sure to put a nice fuse in line right up close near where you tap the power though. Don't want to burn the car down after all this effort.

oh, for some reason i was thinking that 12v wasn't live unless the key was past position 2, and once i shut the car down it'd shut down too, whoops.
in that case i might do a signal wire tap into something which is hot past pos 2, since i got the 195FH harness which is relay based anyway.
actually.....with the aux fan unplugged those connections are nice and available..hmmmmMMMmm

going by this it's just a matter of using the blue wire specifically

Put down the "wiring color codes for other chassis and engines" and slowly step away son.
according to this:
https://www.newtis.info/tisv2/a/en/e...ic-fan/wuCN5aU
You would think you want the BLACK (SW = Schwartz) wire for the power at the aux fan. The aux fan is PWM ground switched via the BLUE wire, which would be great if you could use both black and blue to turn your relay on, but your plainjane telegraph era technology relay won't live long trying to PWM switch! and, the black wire is powered by a "terminal 30" fuse which is permanent power, not switched, so , that's no good as your emergency override supply.
With some work, you might be able to get inside the aux fan and tap it's driver circuit, and basically drive the new aux fan w same sweet DME integrated circuit as the aux fan , but, that seems like it's prob out of your comfort zone and more work than you want to do roadside mid trip.
So you're back to needing power from "something" under the hood for your manual relay switch. You know what I'd try? Fog lights. Then you can use the fog lights as the manual fan switch from the cockpit. Of course you'll be drivin w your lights on all the time but hell just pretend you're a fan of DRLs.

i had thought of headlights, but forgot that the fogs can be turned on whenever as long as the lights are in auto mode even during the day, not to mention it's an easy top of the bay tap.

Why don't you just get 12 volts from the top post on bank 2 valve cover?
indeed, skip the need for a manual switch, i still have some of those posi-tap connectors which i used for the trailer harness wiring, and i think i love them now.

They suck. But you're not a man of fine distinctions, so they seem about right, and I'm sure they'll work to do the job for the duration.
Keep in mind the fogs WILL go off when you hit the highbeams, but that should be manageable. Remember the fan is doing nothing over 30-40... How often are highbeams required below 40? At least in a stopgap / finish the trip situation like this....

OH ABSOLUTELY - I wasn't meaning to say they'd be OK for the main power, just for his 'turn on' workaround. (they still suck tho).
For that he needs BIG ASS proper connections with no hinky stuff. That should be done only with a really quality big butt splice and well taped up, or, soldering and heat shrink etc.
For the "always on" power he SHOULD be able to use the Black Wire for the factory Aux fan. That would be a tidy way to keep wires tidy and away from the engine, leverage the factory fusing, no extra ugly wires, etc. I'd probably try to do that...
But for a temp solution, given the current 'situation', and the understandable desire to get back on the damn road, the jumpstart terminal would be OK if that seems faster.

considering the crimps came with the spal kit they'll suffice for now
but man that fan just sucks heat like a vacuum, i cant get the temps above 97 on this triple digit day in Mesa, although that's without the trailer

Nothing wrong with it at 97C, actually that very good.
Just wait until you get the Aux fan replaced, you'll be cranking that AC down to 60 F with no worries.
It's 101 here today, but only 12% humidity, still hot.

The aux fan pushes air thru the condenser and radiator, your new fan pulls the air thru from the back side, they help each other out.
Just got caught up on your instagram, taking HWY17 from watsonville in to the bay?

the answer to the miata question is it's stored in a car storage warehouse back in MA and i will be shipping it to SF once i have more permanent residence, i'm in (very nice) corporate housing for 30 days which gives me time to apartment shop.
i only check this thread like once a day, usually less, i've been kinda busy if you haven't noticed.
once things settle down i'll do a post-trip debrief with performance and gas mileage etc

Well, well, well; How did the trip unfold?
You guys could have reminded our friend to mount a dash-cam for the trip.
That was a really great undertaking!!
{sigh}
Check his instagram as explained exactly above. He posted a zillion great pix of the trip. I didn't follow all the details and posts, only popped in every few days, but there are a million pix and narrative of his trip, he actually did pretty good exhaustive job of telling his trip story.
Good victory for the ol' E39T tho'! No major issues really, since you can't count the bunny-blast as a mech failure.

Actually all the Instagram images are phone pictures. I took a great deal more pictures using my dash cam which has a picture taking feature as well as a feature to manually record several minutes. The bunny strike video was from that.
