Aftermarket Radiator Fans

[smithcg]

When i bought my FD, certain parts were removed, reducing price as was going to upgrade them anyway

Replaced the radiator, but the fans that came with the new radiator have to leads, im guessing + and - however the standard FD wiring harness has 4

Ive looked at a wiring diagram to little avail lol, i must be missing something >.<

Bassically if someone could inform me what wires of the standard wiring are + and - and what the otheres are for future reference

Thankss

The standard radiator fans have 3 speed settings, low, medium and high. There are 4 fan relays. Both fan motors share 2 of the 4 relays. The remaining 2 relays, one goes to one motor only and the other goes only to the other motor. Therefore each fan motor has 4 wires, one is a ground wire, 2 wires go to the 2 shared relays and the remaining wire goes to its own relay.

Basically the black wire on each fan connector is a ground wire, so they can be wired up to each respective negative wire on your aftermarket fans.

The remaining 3 wires on each fan connector can be wired up to each positive wire on your new fans. So 3 wires connected to one positive wire.

I\'ve made a circuit (along with my electrician genius... ) to better control aftermaket fan, having them working with "stock" configuration (3 speed) or go manually...
