Q:I bought a bathroom fan timer and tried to install it. It has four wires and the wall switch circuit has only 3 wires. What do I do?

3 Wire Switch

Q:I have a bathroom exhaust fan with a light and heater function. The Heater has a red and white wire and the fan and lights have a black, a blue and two whites. There is a three switch outlet on the wall in the bathroom controlling these functions. In the attic there are 3 different wires going to the exhaust fan that I can't find out how to connect. There are 3 blacks, 3 whites and 3 grounds. How should I hook the switch to the exhaust fan wires? Please help

Blue, black, and red are all hot wires. Just attach each hot wire and its corresponding white wire to each switches black hot wire and white wire. When finished each switch will turn on the heater, light, or fan.

Q:How do I tell which wire is positive and which wire is negative on the door speakers and the rear speakers?

The one with stripe is negative.

Q:has black wires.

Two black wires in the box would be a hot from the supply and a switched hot to the load. If the timer has only two wires then it should be pretty easy to just connect them. If they are marked line and load then you would have to hook the wire for line to the wire in the box that is always hot from the supply and the other to the wire marked load. If you are still unsure then it really is not a job for you alone, enlist the help of someone with a bit more experience or even an electrician.

Q:need to know how to properly wire this amp in a truck

wow I have never heard of this amp until u mentioned it. the ratings seem good. ur best option would be to call sonic electronics have them send you a manual on how to wire this amp. they sell this amp. I mean u ask how to properly wire it. wire it to get power ? or to the woofers ? red wire + goes to your battery. black wire - goes to your ground (not your battery) to the frame of ur vehicle. then u need a blue wire, your remote this wire goes to ur stereo's remote wire it should be the same color or it will be marked. but if u do not know how to hook up an amplifier u should go to a professional shop due to the fact if u improperly hook ur amp up YOU CAN START A FIRE IN YOUR CAR.

Q:I have a 2000 Subaru Outback, and I can get the thing working, but it does not save any of my settings. i know its my accessory wire because the radio will not turn on from any other wire.. soo help please

There are two wires that you must hook up. One is for continuous power so that the settings are saved, the other is for power to the radio. If you had purchased your equipment from Crutchfield, you would have gotten free installation instructions and a wiring harness that would hook directly to your Subaru wiring - saving you a great deal of time and trouble.

Q:wiring diagrams

In the uk the best place to fit a power pump is in the cupboard with the emersion heater. Simply fit another spur fed from the existing one the conections are the same as a 3pin plug brown =live blue=neutral and green/yellow=earth the pump has an internal switch that only operates when you turn on the shower

Q:remote 2 wires for power black - white also 3 wires to goto fan/light ? white - black - red

Q:Like I hear people say If you have good Wires you will have good bass. What is good wiring. What is the best wires I can get. Help me I'm new at this. Post some links or Something. 5 stars for best. Thanks!

Mainly you don't want to use wires that are too small. 14 gauge is a good size to use. Using too thin wires makes the resistance too high and causes it to not work right. With small wiring on the power side the amp can't get enough power to work right and on the speaker side the speakers won't sound like they should. Going with thicker wires is a waste of money if you don't specifically need it.

Q:I just purchased a Pyle Audio aftermarket radio. The wiring is very different actually. It only has 2 single speaker wires (1for each side). So do I hook up multiple wires to one wire or what? I was thinking that I hook up the left front and rear speakers to the left speaker wire and vice versa for the other side. Need some advice.

Wow. I haven't seen a car stereo with that style of wiring in 20 years. Their is no manual online so I am going to assume that it is setup the same as stereos made in the 1980's. You are correct, both left speaker positives go to the left channel wire and the same for the right side. All four speaker negatives go to the ground wire. That means a total of six wires being connected together ( ground from stereo, ground from car, four speaker negatives ).and the red goes to full time battery power. The pics I have seen do not show a yellow memory wire, so you will have to remember to turn the stereo off when you get out of the car. Or it will play til it runs the battery down. Also, you didn't say what kind of car you have, but if it's a modern car with fuel injection and a ECM, I would bet you are going to have ignition noise problems. It's one of the many reasons people stopped using common ground car stereos.
