I got my efans and a controller. I have not upgraded my alternator yet..
Anyway...was wondering if anyone who has done this or (not) has some pics of their wiring.
I know I need to wire to battery, and ignition on, and a/c. I want to see how others have done this, so I can get an idea of where I can go with the wires. I want to do it right the first time, and not have to worry about it. Pics would be ideal.
thx for any help.

pics anyone? Would like to see how you guys wire up under 'da hood.

I don't have any pics, but I did several upgrades at one time, serpentine setup, 100 amp alternator, headlight relays, electric fans wired with relays. I don't have a controller for my fans yet, they're just wired to come on with the ignition.

i ran a 3 position switch, on off on . one wire from ign unfused to the middle post on my switch. i used 2 relays (40 amp bosch style) one on wire to one relay, and another on wire to another relay. i ran a big 8 or 10 gage wire from the battery to a junction block. when 1 relay is powered up it runs the motors full speed with about 10.5 volts draw. i run the other relay through an old ballast resistor that drops the voltage to the motor to about 4.5 volts for the low speed setting. i used 4 giant sized zip ties (police hogties) through the fins on my radiator to hold up the fans i have. my fans are either audi or beemer and they really pull when theyre powered up vtblazer has a detailed post with pics in the 69-72 blazer section. if you see my post there are links to his post in it. my pics are not all that good because i took mine after i finished.
