Battery dies in a few hours 1 time, might last days the next time. Replaced battery, failed load test. Replaced starter, excessive draw while cranking.Replaced radio, had a internal short causing it to stay powered up on occasion. I have isolated it to the rear fuse box under the seat by the battery.

The car has remote start so there is a brake in the wires that come from switch on the hood latch. It gives me hood open all the time therefor I can never put the alarm on. I have replaced the hood latch assy to no avail. I need to know where the 3 wires go so I can replace them. A wirering diagram would be helpful.
