Taurus efan wiring

[88turboii]

I've got a build thread that has gotten overwhelmingly bogged down by my own noobishness. I figured it would be more helpful to create a thread specific to this so that others can learn more easily from what I have done wrong and right.

I don't mind putting my mistakes out there. I do many things well, but I'm learning when it comes to cars, rotaries, and electronics. That being said, there is no shame in learning, but there is shame in repeating the same mistakes.... and if anyone else can learn from what I've done wrong and right then world is a better place where money grows on trees, we fart roses, etc etc.

With my rebuild I added a Taurus efan sourced from a junkyard trip.

Here is the diagram I used for wiring my efan.


I used 10ga all around for wiring.
85 - to Check Connector
30 - grounded to battery
87 - fan(-), fan(+) with circuit breaker (40a) to battery(+)
I haven't wired in idle up yet.

What happened wrong is that I ran 85 to Check Connector under my battery tray which then (unknown to me) got pinched. Pressure and vibration eventually wore down the insulation and was creating a sporadic short and blowing my EGI fuse.

What I'm wondering is if there is a better way to wire in my efan than what I am doing?

I've gotten some advice to draw power from the starter. I assume that means the fused power directly to the fan. But I don't understand how that is better/different than simply taking it off the battery?

Is there a better source for my 12V IGN source?

Also is there a better way than what I have done to protect the spade terminal wiring coming off my relay. I have the relay mounted behind the bumper with the other OEM relays. What I did to protect the spadeterminals on the relay from the elements is to inject silicon caulk. I taped them up to create a "mold", injected the caulk into it, let it harden and removed the tape. It worked but is ugly, and the terminals are now a permanent fixture. With replacing the 85 to 12V IGN I now have to either create a butt crimp, solder two wires together, or replace the whole relay. What can I do better/different?
