    they didn't work on my high side...it would blow a 60 amp fuse. i have the 70 amp relay now and no problems...:yup: mine is wired through a ...
    on-off-on toggle, with the high side also wired to come on with the A/C.
    i also noticed a big diff. in the fan speed when i ran it on the 70 amp relay...

    ...:Handshake...

    What PGARFDS posted was for a two speed setup. From the link:

    [​IMG]

    [​IMG]

    The two diagrams above show how to build and wire an auto relay switched 2-speed FORD TAURUS fan.
    Parts needed......10 guage wire for the power circuit. 18 guage wire for the control cicuit.
    Three relays..... 1) High speed relay, Tyco VF7-12V,70amps
    2)Low speed relay and Aux relay, standard BOSCH relays
    Two switches,,,,.1)Low speed temp. switch- Adj. Flexilite, FLX-31147 from SUMMIT.
    2)High speed temp. switch from Standard Motor Products, TS-158 or TS-392.
    I put the adj. low speed switch and the three relays in seperate relay boxes and mounted them in the engine comp. The high speed temp switch I mounted where one of the heater hoses went. Est. cost of parts, less the fan, is $50.00 . 10 guage wire is used in the power circuit and 18 guage in the control circuit. The 12V switched control circuit can be connected to any live connection with ignition on.
    The control circuit shown is as follows..... When the temp. reaches your set low speed figure, let's say 190 deg.the low speed relay is energized thru pin 86, 85 connects to 87A of the AUX relay and pulls 30 of that relay, 87 of the low speed relay and 30 are closed sending power to the fan to run at low speed.
    When the temp. reaches your high speed switch figure, let's say 210 deg. pin 86 of the AUX. relay energizes thru 85 and 30 releases from 87A of the low speed relay and connects with 85 of the high speed relay which thru 87 of that relay powers the fan to run at high speed.
    ARE we confused yet?????
    When the temp falls below the high speed swich figure the AUX relay will switch back to the low speed relay.
    Therfore low and high speeds will never be on at the same time and you will have the following conditions...
    1) No fan on.
    2) Low speed on.
    3) High speed on.

    No problem with resurrecting a thread that still has relevance.

    Taurus fan is still working great.

    :yup:

    Good stuff in here. Still love my Escort fan, essentially the same thing. (No longer on a 30a fuse, but a 50a circuit breaker)

    My experience... The 30a fuse blew twice in three weeks, and the 50a circuit breaker has never tripped. So, usually less than 30 amps, probably much less, occasionally more on startup. But not more than 50.

    Yea, once they are up to speed, I don't think they draw a whole lot. But the current spikes sharply on start up.

    I used a...Volvo relay...it works off a...20 amp fuse...:thumbs2:
    it is for both speeds...
    you set the low side and the high side to come on at what temp you like. it has a sensor wire for both sides. the low comes on to get the fan moving then when it reaches the high side temp, it shuts the low off a second after the high comes on...
    I got some from...Pull-A-Part and also ordered a new one for...$55.
    here is a pic. of one w/plugs from Pull-A-Part....$8
