Merry Christmas to you & yours.
If memory serves me right, there are 2 or 3 Blue wires that went to the "old carb". Any one of those will work for the choke power, as it just needs switched power from the ignition switch.
For the fan. Try a jumper wire from the plug for the thermoswitch to Battery -, Fan should come on, key must be "on". If it works that way, check for a short length of wire from the top crossbrace of the radiator to the radiator support. That is a bonding wire to ground the radiator, you need that...
If that doesn't work, posiblity of fan being bad. You can unplug it and run jumper wires from it's connector to the battery. Polarity doesn't really matter as you're just testing the motor.

I'd be happy to help with questions on this.
On mine, other than getting the linkage/cable alignment right, there was no issues with it being 180* from norm. Took me some time getting things right so I had both proper idle and full WOT of the carb.
Weber to intake matching is not the best, either way you sit the carb. It would be better if the carb was more centered over the intake, but that would require a custom built intake.
I had that same intake/carb setup on 3 different BRAT engines, and used it on another EA81 in the '88 GL10 Wagon I had on the road for a short time. That car had wiring issues so we couldn't run the stock SPFI.
