Great deal.

As always, if you're savvy, search your vehicle on iDatalink's page [idatalink.com] to find harness, compatibility, and wiring details. Once the results pop up, the DC3 column is what we're using in this bundle. In the "Required Accessories" row, you'll see harness info. HRN-DC3 is a hardwire kit. Each wire will be connected by hand via splice. ADS-THR-XX## is a T-harness. Most wires will be connected via OE connectors. Pick one. T-Harness is always preferred, but not available for all vehicles.

If you want to go deeper, then click the picture of the DC3. Then click Download Guide. This will give you the install guide, for both hardwire and T-Harness installations. So DC3 is flashed to your make/model vehicle, wires are installed, DC3 is programmed to your specific exact vehicle, keyfobs are paired, tach is learned, that's about it!

What if my car doesn't pull up? I don't see the DC3 column? Your car likely isn't compatible. BMW, Mercedes, Audi, VW, I'm looking at you. But talk to your local installer. Remote start options are out there for almost every car.

Had it installed on 2 cars. Never failed. The 1 way version was on sale this past weekend (this 2 way was regular price), so I got that installed. Typical wait time used to be weeks.. this time, was able to get an appointment in 2 days.

Installation seems $169.98 for me. Toyota sienna hybrid. What I am missing?

Got this for $240 pre-covid. Just ordered another for my daughter's car. Was waiting for this one to go on sale. Be sure you add on the installation for $150 or so. It comes off during checkout.

Only thing I don't get is it's including a Viper door lock something and charging me $10. Since it's not a Viper system, I have no idea why it's doing that. I'll just take it up with them at the store.
