I am in a pickle and can't get any solid answers. Here is my situation... My vehicle came with no power locks at all. I bought a kit, installed all the actuators (2 wire system), and everything with the keyless entry (Avital 2101L) works. However, for whatever reason, they did not add a wire in the harness to have a hard button inside the vehicle lock and unlock it. I have attached the diagram for the keyless entry system, and marked the two relay's wires with red and green dots. The second module allows me to use a button to trigger another relay to unlock or lock the system. I have attached that diagram as well. Will I be able to connect the outputs of the relays to each other (lock and lock, unlock and unlock) without any issues? or will I need to add diodes into it, to isolate the current from backfeeding the respective modules?
