Wiring Specialties

I know about this place many years ago when I was looking into the idea of doing a engine swap on one of my previous vehicles. From what I can tell they have some really nice stuff. I would have loved to work with them. As of now I have a different vehicle that I was simply looking to do an electric fan conversion too.

I love working with Wiring Specialties! If you need help with your order, the sales team will guide you through the order process. They helped make sure I had everything I needed to get my 240 running and explained every sensor upgrade and why it’s worth it to upgrade. Thank you for the help!

Very helpful and show strong passion towards this! I will buy from them again! I will add pictures when my harness gets here!

It‘s a joke to call itself wiring specialties and deliver such a bad Harness for this price. After Month we fix it with help from local wiring company. In the end we spend more money during find the issues and solve them, then if we just made a new one from the s
