I'm for sure a n00b when it comes to wiring, so I figured it'd be best for me to consult people who know before I mess things up.



First problem;

wiring e-fan to a relay and switch (switch is temporary)

The relay has 5 wires. According to the guy at Parts Express, black - ground, white + switch, blue + battery, red not connected, yellow - fan +.

The switch has 3 connections, one for ground, acc and power source.

the fan has negative and positive.



Like I said, I'm a n00b, but this seems to be pretty simple. After hours of messing with this, I gave up.



Second problem;

I just bought an Innovate LC-1 w/ DB gauge. Basically, I just don't fully understand how to connect everything. I've looked at some things on the forums but just about everyone has a 7th wire and that throws me off track. Also, I was confused as to whether to wires from the back of the gauge are to be spliced in with the wires from the o2 sensor... I'm stumped!



Third problem;

My friend wired up 3 gauges, the e-fan (before we bought the relay - has been removed), indiglo gauges (switched on with fan, which was kinda really stupid - will be wired differently) all spliced into the + and - of the cigarette lighter. Is this safe? If so, is it safe to tap power from this for the LC-1 or should I tap a different source?



Thanks for the help in advance.

Let me know if something doesn't make sense here and I'll do my best to clear it up.

1. look up how a relay works, its pretty simple, it lets you run low amp/voltage to the switch, so it doesnt get fried, and the thing you're switching gets a high amp/volt connection. basically when you flip the switch, it turns the relay on. switch isnt a good idea, you will forget it at some point



2. did you buy the gauge one? i have the lm1, it just plugs into the cigarette lighter....



3. gauges are fine on the cigarette lighter circuit, another good spot is the power wire for the radio. the Efan needs to get its main power somewhere under the hood.
