Electrical Load usually indicates a short circuit. Also, know that if your ECU's temp sensor isn't connected, your car will not start. Realize that there are 2 temp sensors: one for your gauge and one for your ECU. The bananna plug is the gauge sensor. If that's screwed, your car will operate fine, but your temp will always read zero. The temp sensor for the ECU actually has a plastic connector, and it's located in the same area (LH side of the head) but just below and towards the front of the car. If THAT's screwed, the ECU won't start your car.
