Re: Hotwire kit differences
I worked on a Sy that had this harness. The two wires in the weather pack plug were backwards. Not only did it not run, but the fuel level sender got fried too because it was fed with +12 Volts. I had to replace the sender unit. I was surprised that A: The vendor for the harness made such a stupid mistake and didn't catch it. B: Whoever installed it didn't notice that the grey and purple wires didn't match up to each other, and check it out further. Would have taken like 30 seconds to de-pin and switch them.
I just make my own harnesses. Why pay 5X what it costs to make yourself, and perhaps a lot more if they make a stupid mistake that costs you time and a new sending unit to boot?
