Fan / Electrical connectors

Hi folks,

I have an 09 F4 312RR, and like many of you, am dealing with excessive heat on city streets and in high traffic areas.

I'm getting the MV "updated" impeller installed in a couple weeks, but would also like to install a manual override switch for the fans.

Rather than cut and splice, I'd like to build a Y connector, with the weatherproof connectors, and then just clip it inline. Basically, just disconnect the fan, put my extension inline, and connect that to the fan.

The problem is, I can't, for the life of me, identify those connectors, or where I can buy a few of them for this purpose.

Can anyone help me ID these, or know of a vendor that sells them in the US? (South SF Bay area ideally)

IMO Don't worry about the fan.
The original impeller doesn't flow much (read zip) when idling and switching fans on earlier makes no difference. Fit the new impeller - that will fix the circulation and the fan will cool things down no probs.
I find my 750 will cool down when the fans come on (while stationary) if I just increase the idle to about 3K - go figure.

I disagree. Switching the fans on with a manual switch makes all the difference in the world. 167F at idle. Just turn them on below 40 mph and it'll run at 180-185 all day long.

I've found the Tyco Superseal, that look an awful lot like the connectors on my bike. I think that I'll order a few sets and give it a go.

I'm nervous about carving up the factory harness, and also might add in a diode to protect the ECU.

Can anyone confirm if these Tyco Superseal are the right format connectors?

...and Lee, many thanks for all the work you've done in pioneering these fan hacks.

The best way to wire a switch is to run an independant circut from the battery. Not all that hard and avoids any contact/backfeed to the ecu.

That's what I'm planning, but I'm planning on connecting into the fan at the interconnect. This way, I don't have to cut or splice anything. The diode is to protect the ecu when the factory relay opens, and I have the manual override turned on.
