Chassis Harness makes one of the best plug and play E36 replacement chassis wiring harnesses along with a very competitive price point. They were very helpful through the entire process of configuring my custom harness as well as assisting in the installation. Anyone that is looking to replace their chassis harness in their project car, Chassis Harness LLC is a great option!

Amazing communication and amazing product couldn’t be happier

One of the best customer services I have ever dealt with. Sean was amazing and answering all my questions. The kit was customized to my need with some twists to make abs functional. Installing was straightforward with the instructions that came with the kit. I would recommend chassis harness to anyone building a race car. Thank you guys for your amazing work

Amazing customer service from the start. And a product that surpassed my expectations. Customs built for application down to every single last lead. Absolute heat

Literally solve all of your wiring issues in one step! Amazing products made with quality and care. I have a custom chassis harness in my E46 wagon and I couldn’t be more happy with it. Took me 20 minutes to install the entire harness. 10/10 would recommend these products!!

Love my chassis harness! Plugged right in and worked perfectly!

Amazing company, with a really solid product, at a really solid price! Very easy to work with and very customizable. My S14 has a tube rear and rear firewall, so i had requested a bulk head connection for a easy disconnect from the rear section, and thats just what i got!. The loom and connectors just feel durable while holding them, and the force it takes to connect and disconnect the fresh connectors, you just know you wont have any issues. Lookin forwards to watching this company and product line grow throughout their future!

Could not recommend Chassis harness enough to anyone. when stripping my comp drift car my full harness was cut, when looking to start wiring my head was baffled. Came across these guys and what a product!!! Customer service is amazing from contacting them to talk about the product to aftercare. Simple to install everything's labelled high quality product.

If you need wiring speak to these guys you won't regret it.

Where do I begin? I have 31 year old s13, slowly chipping away with every bump I hit, an electrical problem or catastrophe bound to happen. Till I was introduced to Chassis Harness, TOP TIER customer service always answering in a timely manner. No hesitation to answer any question of the product and services they provide. Stop stressing about that 30+ wire do yourself the favor and get a new chassis harness.

I installed the 4 door window harness in my e36. I haven’t had power windows in my car for about 7-8 years the easiest install. I recommend this to anyone who has a race car and wants great quality products and the absolute best customer service!! Thanks again to the guys over at chassis harness !!

Awesome company to work with, answers any questions right away from the time you even ask about ordering a harness all the way to final install and beyond. The harness itself is beautifully done and lays out to all connections perfectly. Couldn’t recommend them more

Best customer service, I’ve ever dealt with.
Quality on products 10out of 10
Will definitely recommend to anyone with a e36/e46.

Amazing company to work with, that puts out an amazing product! Recently installed my chassis harness and window harness that I had ordered. Everything works flawlessly. Factory tumbler works, factory cluster works, and the best part is that they can pin out the factory X20 plug for your E36 engine harness! Again - very easy company to work with. Great customer service and even better product!!
