Wiring a 2 speed Taurus fan

Not sure how much info I'll get here but I figured I would give it a chance. I got a taurus fan off of a 3.8 on ebay last night how did you guys wire yours up? The high speed takes a lot of amps, I've never really messed with anything that high before so what do I need to use. The power wire to the high speed will be 10 gauge, low speed will be 14. Any info will be great.

Do you have a two-speed fan switch you're using?

I think he's using the a/c as the trigger for high speed. low speed is pretty adequate for keeping the engine cool. Also when it's hot enough where the low speed may not cut it, the a/c is probably on. The high speed can definitely handle the a/c and engine heat.

Have you seen the prices on those? I can wire up my own for 1/2 the cost.

Exactly, I'm doing it basically the same as yours I just wanted to see what other people did as well. I don't know if anyone else is running one on here though.

No worries, i bet some people are using different setups. I just prefer overkill on somethings. 10ga wire, 100% soldered/heat shrink connections, 50a breaker for the high side, 70a relays, etc, etc.

You can go with lighter duty stuff im sure, but longevity and pesky voltage drop issues that aren't obvious will give you grief one day.

Oh yeah I'm with you I would rather make it stronger than needed. So you did go with a 50 amp breaker, your how-to thread on RPS says 30 amp. I was wondering why you did that lol, makes sense now. I think I'm just going to go ahead and do it the same way you did, should work fine. Oh random question, what program did you use to create the wiring diagram in that thread?

well the maxi fuse i had was 30 or 40a at the time of that post. however it was a junkyard maxi-fuse holder...that actually melted the plastic, and blew the 40a fuse. So to get around that, i bought a 50a breaker (that i can just reset), that is wired with two bulky ring-eyes on studs. No loose connections, no wimpy plastic, no digging for a 40a maxi-fuse if for some reason it spikes and pops it.

Awesome I was going to ask you what kind of breaker you used but that answers it. I'm going to go ahead and order everything then, thanks! Now just have to order my pullies and I can get installing all this junk.
