Yes I know this, as I stated before Dr. Tweak (now with Phoenix Tuning) did the harness's for Tech2. They say the problem and corrected it, they stopped having hem make or touch any harness's and this is where I came in. Yes we have made improvements on our products especially in the harness department, there is a night and day difference in the quality of the harness's compared to who we used to use.
As for the kits you are referring too, a swap kit? or the harness's? The only change we have made with our kits is going from 1500* paint to powder coating them. We still use 10ga mild steel that is laser cut and MIG welded. The Driveshaft is 100% brand new and nothing nothing reused.
I agree with you on how crappy the harness work was before, this was a major problem with our kits. I have come to this business with my professional expertise and now our harness's are 2nd to none, we still are cheaper than anyone else and all extra safety precautions and devices (fuel safety shutoff device $50, diodes, relays etc) are included with every harness for free. I only charge my cost for parts that have to be replaced and never a labor charge for replacing connectors/wiring.
Again as I stated very early on in this post, I'm sorry for anyone who had a bad harness from us, We have corrected that mistake of using another person. I only pursued you to find out what we had done or are doing wrong, this is the company I work for and I strive make everything we do top notch and professional.
