New Wiring Harness

[DoubleL]

I was wondering if any of you had purchased this or any other harness products from this place before:

My fuel gauge just had a melt down (literally) It looks like the damage was contained to the plug and upper part of gauge harness. I then noticed the PO had a jury rigged wire in the fuse block for the sending unit. I disconnected and removed it and cleaned up the burnt plug/wires on my cluster.
I will be replacing the sending unit with a new wire set and I have wanted to put full gauges in my truck so I think to be safe and do it the right way I am going to replace the whole dash harness.
I can't afford to rewire the whole truck and it's my daily driver so I am going to do it one harness at a time as I can pay cash.
Any one used their electrical products?
Thank You!!!
