Hi XXXXXX,
No need to chop any wires,It sounds more like you have a faulty sensor on the overheat side of things, if the alarm keeps sounding disconnect he brown/tan wire this will cut out the alarm,
You need to be a little cautious when adding oil to the fuel and keeping the oil system connected, the reason being is that you will be putting double oil through the system which can do damage as it causes a weak fuel mix which can cause piston damage. I would disconnect the main oil line into the engine leave about 3" protruding and use a suitable sized bolt and jubilee clip to block the line off, then add 50:1 oil straight to the tank. But again you need to ascertain that the engine is not actually overheating, when the engine is running put your hand on the cylinder head(use caution there are moving parts that are not forgiving) it should be just about bearable heat and not so hot that it will scald, can be worth splashing droplets of water on the head if they bubble and boil its way too hot.
