Electric fan install help.

I agree on using good parts, however, I've even heard sketchy things about Griffins having "bonding failures". They might be better quality, sure, but unless you're using the universal ones, the price is a bit eye opening. So, I figured I'd "chance it" on the champion which is all welded, and honestly, could be repaired/recored later if needed. The quality isn't phenomenal, but no functional issues.

I've been advocating the used OEM Bosch fans vs the dorman ones if you can because of my experience with other dorman parts (all imported), and their seriously sketchy quality, you need to look only at the trans pan on my dad's 4L60E where you cannot use a copper washer because the drain plug surface is not anywhere near flat. Yes, I used the dorman resistor/diode pack...BUT the failure mode on that doesn't disable high speed. I'm also pretty sure you cannot buy it from ford at this point.

Wiring: solder and heat shrink if at all possible for splices. Or, use the right tool/ends for everything else.
