GM Passlock Bypass Tip (no wire cutting)
I just bypassed my Passlock II. I read all the instructions on the
net and they all involve cutting the yellow wire. I HATE to cut wires, especially when that cut wire can leave you stranded. From what I understand there are 2 types of Passlock II. The type in my vehicle has a lock cylinder that does not supply the resistor code when the cylinder is moved from OFF to RUN. Rather the resistor code is supplied when the cylinder is move to CRANK, and the resistor code continues to be supplied when the cylinder is released back to RUN (the code will finally disappear when the cylinder is moved back to OFF). In this situation, you can connect your bypass resistor/relay circuit directly from the yellow to black wire without having to cut them. When the remote starter activates, it will switch-in the bypass resister and since the lock cylinder is open-circuit, the lock cylinder will not interfere with the bypass resistor. Likewise, when you get in the car, put in your key and rotate the cylinder to RUN, as noted above, the lock cylinder is still open circuit and does not interfere with the bypass resistor. Of course, when you are not using the remote starter, all of the original factory wiring is in-place and things work as normal. NO CUTTING. |
