Re-wiring Fans
I noticed that the fan loom on my cars is starting to look a bit shabby so before the and after reading a artical stu wrote for fast ford ive decided its time to get the soldering iron out and do something about it,
What im after is advice on what i need (ie relays) and suggestions on how i go about doing it,
I notice in stus artical he suggests using a relay per fan, has any1 else done this?
any suggestions welcome ta

I've found that life I needed.. It's HERE!!
When you are using normal 30A or 40A relays it's a good ida to use one relay per fan.
Fan's draw a lot of current and the connectors and relay's can become very hot.
I always use high amps relays from Bosch: 0 332 002 156. With such a relay you only need one. It may seem to be overkill, but this relay will work forever.
It's a good idea to use the thermo switch in the radiator parallel with a switch and/or control from the ecu. It's also a good idea to power the relay directly from the battery, so it can cool the radiator even when the ignition is turned off.
