Wish I would’ve gotten this product sooner. Helps a lot with engine warm-up time and works perfectly. Install was a breeze thanks to the detailed instructions and video.

Pro: very easy to install, and the instructions were very easy to understand. Couldn't have asked for better instructions
Cons: the idle elevation level cannot be controlled. But that does not affect the kit. It still works exactly how it's supposed to.

Great investment

Kit comes with everything needed to install as well as a great install guide. Truck warms up a lot quicker and also keeps oil pressure up. Definitely recommend this product.

Great kit

Shipping was good. Simple install, just follow along with the YouTube video and you're golden! Works great on my 2003 duramax. Simple and effective. Great product

Definitely worth the price of admission!!

Came on time and did exactly as advertised. Instructions are spot on. Less than an hour of work and a 12 minute head start, you'll have a warm truck. Couldnt be happier with nu purchase

This kit was right on! It's a little funny to pay 20 for a wife and some zip ties but it is well worth it! The instructions are worth the 20 alone and the fact that I don't have an additional switch or extra holes in my dash is awesome. The hardest part was getting the grey retainer off of my ECM and back on- apparently it only goes on one way. Well done Merchant Auto!

Nice Kit/ Worth The Money

Install was not great but not bad. Took a little more time in my case because the ECM had been worked on before I had it. I didn't have the room to just pull the connector out in the open like in the video in my case. Just make sure you have a good connection with the blue connector! Over all in my case it was still well worth it in the end. I would buy it again!

Nice, simple, as advertised. So why didn't GM do it to begin with? Right?
