Cooling fan sub harness

OK well during the rebuild of my G, the wiring harness for the fans ( and other bits ) was smashed.... So I have a bit of a *concern* and need help.
I got new ( er ) sub harnesses with my fan assy,
I got chunks for the engine bay harness from another member here. and used that to " freshen " it all up..
But I remember something was a bit off ( like some colors didn't match )...

The car doesn't overheat... BUT the A/C on REALLY hot days.. has a problem kicking on till I get moving...
The shop manual ( EC-470~476 ) shows point to point wiring with no sub harness shown...

So I'm looking for actual pictures for the 2 fan connectors and or wiring detail.

If I remember correctly I had to guess on a couple of things down there...

Now I know each fan has 2 speeds 1-2 are the power feeds ( blues & red )

3-4 are the grounds...pin 3's are hard ground ( Black ) pin 4's are switched ( Yellow's ).

The fan connector
(tab) ( Twds firewall ) on Fan Assy
2 | 1
-------
4 | 3


So there are a few conditional states... which are a bit confusing.. and I can see a potential of 1 fan being in low , when high is needed.

So any additional info would be great~

Thanks
Mike

Ok I found this

On the pass side fan the Black & yellow are flipped..

and on both connectors the High & low speed are flipped

CHHRRRIISSSTTTTTT

So I have wonky fans and no PROPER depinning tool...
the upshot is when I call for MAX COOLING it's there
and durning low cooling 1 is on high and 1 is on low

OK


(tab) ( Twds firewall ) on Fan Assy
2 | 1 ( hot )
-------
4 | 3 ( ground )


So conditions
1 ( power ) 4 ( ground ) runs ( low speed )
2-3 runs ( low speed )
1-3 runs ( low speed )

NOW
1-2 HOT
3-4 Ground
Runs HIGHER speed ~ 200-300 rpm more

Tested on bench W stock 03 Drivers side fan motor no blades...
