I'm trying to install a remote start?

Here is some general guidance on wiring the Ultra Start U1172-XR Pro 2 remote start system and the Directed 555G-W Passkey 3 Immobilizer bypass module in your 2000 Buick LeSabre. You should always consult the specific wiring diagrams and manuals for your vehicle and the devices you're installing. However, I can offer some general advice on how to wire the two devices together:

Compatibility:
The Ultra Start U1172-XR Pro 2 remote start system and the Directed 555G-W Passkey 3 Immobilizer bypass module should be compatible, as the Directed 555G-W is designed to bypass the GM Passkey 3 immobilizer systems found in many Buick vehicles, including the 2000 LeSabre.

Wiring Connections:
Here are some of the general connections you'll need to make between the two devices:

Connect the remote start's main power wire (usually red) to the vehicle's battery.
Connect the ground wire (usually black) from the remote start system to a solid chassis ground.
Connect the ignition wires from the remote start system to the vehicle's ignition wiring harness. This typically includes the ignition, accessory, and starter wires.
Connect the remote start's tachometer wire (often green) to a tachometer reference wire in the vehicle, if available, or follow the instructions provided to set up tachless operation.
Connect the parking light wire (usually white) from the remote start system to the vehicle's parking light wire.
Connect the brake shutdown wire (usually brown) from the remote start system to the vehicle's brake switch wire.
Connect the hood pin shutdown wire (usually gray) from the remote start system to a hood pin switch, if available.
For the Directed 555G-W bypass module:

Connect the 555G-W's main power wire (red) to the remote start's main power source (same as the battery connection for the remote start).
Connect the ground wire (black) from the bypass module to a solid chassis ground.
Connect the blue wire from the bypass module to the remote start's ground-when-running output wire.
Connect the violet wire from the bypass module to the vehicle's Passkey 3 data wire.
Follow the instructions provided with the 555G-W for programming the module and learning the vehicle's key information.
Note that these are general guidelines, and specific colors and connections may vary between models and years. Always refer to the installation manuals for your specific devices and consult a professional installer if you're unsure about any of the connections.

Disclaimer: Working with automotive electrical systems can be dangerous and may result in damage to your vehicle, devices, or personal injury if done incorrectly. If you are not confident in your ability to safely install these devices, consult with a professional installer.
