Our verdict

The THAR-GM7 is the T-harness in our EVO-GMT7 kit, for the key-start GM models in the vehicle list on this page, mostly 2010 to 2023. It works with the Fortin EVO-ALL and the EVO-ONE. If you don't have a Fortin module yet, get the EVO-GMT7 kit instead: the module and this harness together, with the module programmed for your vehicle before it ships. Buy the harness on its own when you already have the module, or to replace a damaged one.

Jeff BatesOwner, Lockdown Security · Installing since 2003

A T-harness plugs into your vehicle's own connectors and into the Fortin module, so there's far less wiring than a hardwired install. It needs a Fortin module to work: see which ones below, or get the kit with both.

  • Plugs into your vehicle's own connectors
  • Needs a Fortin module (not included)
  • Or get the kit: module and harness together
  • Lifetime installation warranty when we install it
  • Free shipping on orders over $200

Installing it

Buy it from us and we can install it for you, or you can do it yourself.

At our shop or at your place

Drop it off or wait at our Markham shop, or we come to you in the GTA. Most installs can be done on-site; a few need the shop.

Lifetime installation warranty

Every install we do comes with our lifetime installation warranty.

Before it ships

Module programmed for your vehicle

Buying the module or the kit from us? Tell us your year, make and model at checkout and we program it before it ships. A vehicle marked DECRYPTOR finishes its programming at the vehicle, with a FLASHLINK if you install it yourself.

Installing it yourself?

Plenty of our customers do. A T-harness plugs into the vehicle's own connectors, but expect to make a few connections too. Check the install difficulty for your vehicle in the list above before you start, and text us your year, make and model with any questions.

Testimonials

  • Exceptionally Helpful

    They were exceptionally helpful despite me going down the DIY route having never installed a remote starter before. There was no T harness kit available for my vehicle which led to a few questions which they thankfully were very helpful with. Mission remote start was successful and I'm super pleased.

  • 10 out of 10

    I would recommend Lockdown security 10 out of 10 times. Leo and his team were professional, fast acting and provided excellent service. I am very happy with my remote starter.

    Jay
    Enjoying a warm vehicle!

  • Responsive, Easy to Use

    Have been using Lockdown Security for years. Just ordered the fifth remote starter from them and installed myself. Their website is easy to use and intuitive. They are responsive and more than willing to answer questions for the DIY customers. Would strongly recommend to anyone looking to purchase a remote starter.

Common questions

Will it fit my vehicle?

Find your vehicle in the vehicle list on this page: it's every vehicle we list this harness's kit for, with a link to that vehicle's page. Not listed? Search by vehicle, or text us your year, make and model.

Is the remote starter included?

No. This is the T-harness only: it connects a Fortin module to your vehicle. The compatibility section shows which Fortin modules take it, and the kit that has both in one box.

Should I buy the kit or the harness on its own?

If you don't have the Fortin module yet, get the kit: the module and this harness together, with the module programmed for your vehicle before it ships. The harness on its own is for when you already have the module, or need to replace a harness.

Which Fortin modules does it work with?

It's on this page under What it works with. Fortin's THAR-ONE harnesses are made for the EVO-ONE only. Fortin's other THAR harnesses work with the EVO-ALL and the EVO-ONE.

Do you install it?

Yes, at our Markham shop or on-site in the GTA, with our lifetime installation warranty. Book an install.

Do you ship across Canada?

Yes. Shipping is free on orders over $200, and $10 under that.

Not sure it fits?

Text us your year, make and model and we'll confirm the right harness before you order.
