Question Ele. fan install questions...

Ok so I've been researching on how to do the ele. fan swap. I'm buying the mark viii fan today/tomorrow. But I cant wait 4+ weeks for the DCControler to get here. So I'm gonna follow the instructions from this link on wiring it up:
http://www.dfwstangs.net/tech/markvi.../markviii.html

My questions:
-Do I need any inline fuses?

-Where can I tap into a 12v key-on source in the engine bay? (The link states they "spliced into the wiring harness near the mass air meter". But I dont have MAF. So I dont know where the link is talking about!?!)

-Also the link says to use an 30amp relay. But I've read that people use a bosch 75amp relay. So which relay should I use?

Thanx

Thanx

You can fun it on a toggle until you do get the relay in. I used a 40 amp circut breaker style fuse inline with it and no problems. I had a 30 amp but it kept tripping and finally burned out.

So are you saying I can just run a toggle switch with an inline fuse w/ no relay to run the fan?

Do you know which amp relay? I'm reading an 30 amp relay is fine, Then an 40 amp relay, Then I'm reading that those arent big enough. And I should run an 75 amp relay... Confusing as all hell..
