Can someone exactly tell me the best way to bring accessory level power into the front of the car???

What I mean by this is when I turn the car to accessory or on - I have a 12v live power to engine. With this said, I don't want a fan relay or a direct battery connection.

If someone knows and even better can identify the wire I can tap into I would greatly appreciate it!!!!!

thanks1

Nobody knows???

I don't know. Get a multimeter or a test light.

This is a tougher question than it initially seems, there are very few acc level wires in the engine bay, almost everything is ecu/relay activated.

I used the wiper motor connection, one of the few hardwired accessories under the hood. Not sure what pin, hopefully you can figure that one out

Appreciate your input. When I looked at the wiring diagrams I noticed everything seemed to be triggered by the cigarette lighter (weird).

I want to install an intercooler fan that comes on with the accessory. I don't believe it should be connected to the radiator fan as I believe the IC system has different requirements for when they should be cooled.

I am not really sure how relay's work, but when I used my multimeter they on the relay fuses they always had power.

Suggestions?

Thanks!

A relay is basically a gated switch. There's a constant power source that runs to it and the gate is either normally open or closed (depending on its function). When a second voltage source is applied to the relay, the gate will close (or open) and supply (or cut) voltage to whatever device. They're mainly used for high draw things like A/C compressors or cooling fans. If you're looking to do a fas thing for your IC, it would be a good idea to use a relay as using smaller gauge wires associated with acc. power might overheat those wires and cause a short.

beat me to it...and with a more tech explaination

Well, here is what I did:

Installed a push button start and eliminated the cig lighter. Fabed a plug for the cig lighter plug (two connections only one is hot) and ran a wire out the firewall hole.

So, yes your research on the wiring diagrams is the easiest.

Relays are simple little neat gadgets. 4 prongs, two are used to send a signal to it, when its triggered a connection is made and the other two prongs have continuity and are used to power something.

Say when you turn the key, the push button has power and when you push the button it trips the relay that makes the connection to the starter.

Sorry didn't mean for this to turn into a s2000 push button post...just easy to explain.

You might want to talk to Max Cooper as he has installed an intercooler fan. I'm pretty sure he has it set up so he controls exactly when it turns on and off.

cool thanks - want to come to Texas and help me find one...

I would still be perfectly happy with the IC fans on all the time as I see a smic heating up during idle (not good) and also really don't see the airflow ever exceeding what the fans will be able to apply given the small IC duct opening and such.

I suppose I could use a thermo relay and just turn down the trigger temperature to very cold so it is always on. - but those things are fairly expensive. That may be the best bet as I wouldn't need a trigger source I could just hot wire it and stick the thermo relay in the IC and be done - right???

Thanks!

So I found this... Problem is the low side for the adjustment is 180 degrees... I'd like it to come on at 80 or so. suggestions?
