"Service was amazing, response time was quick and product was 100% perfect and made my life a bit easier adding in the stereo to my 2017 Silverado"

— Brandon I. (5/5)

Must have!

"I have a 2018 Silverado Custom and easily added an amp and subwoofer with this harness. It took me longer to tune the system than it did to install this harness. The quality of the harness is unbelievable. It looks OEM, you would never guess otherwise. Excellent craftsmanship!! Thank you!"

— David W. (5/5)

Harness

"Great product, couldn't have asked for a better plug and play. No splicing into wiring keeps everything stuck."

— Jose Z. (5/5)

Awesome

"I ordered a harness for my 2018 Silverado and it was so easy to install. I had it installed in like 5 min. I love it cause I can install my amp and sub woofer in my truck using the factory stereo and no tapping into factory wire harness. Love it. Awesome product guys. Will definitely refer you to friends and co-workers."

— Ruthanne T. (5/5)

Perfect for work truck model.

"Perfect for a 2018 Silverado 1500 W/T with 7in screen. Can't get any easier than a plug and play harness! Great quality product!"

— Dustin D. (5/5)

Best plug and play on the market!

"If your wondering on buying a t-harness I’d highly suggest going with LLJ customs! Extremely high quality have won me as a customer for any vehicles I’ll own in the future a fact! Only thing I have to say is lead time on website is just about on point for me took 2.5 weeks instead of 2 other then that I’d say for sure it’s worth the wait! What are you waiting for! Go buy one now!"

— Gustavo I. (5/5)
