the heater bypass is quite simple, if you look at the firewall you will see two medium sized coolant lines, remove them from the firewall and link them together using a proper sized tube, you can purchase a kit at a parts store quite cheaply

the wire on the door latch make sure they are plugged in or unplug it and the light should go out if it does not then it's not that door
