I am looking to buy a replacement lug to connect radio to existing wiring in car where can i get one

Good clamps are available from NAPA, Autozone, O'Reilly's, Pep Boys, Car Quest, and other suppliers. Check to see if the existing wire terminates in a crimped lug. If not you need to look at the new clamps to see whether they are designed for attaching directly to the wire strands or if they require the wires to be gathered and crimped into a lug to go under a single screw. Fasteners to clamp large wire under a screw are similar to photo here.

Just buy a multiplug connection block for this vehicle from existing wires to new radio its easier than messing aroung or use a multimeter and small 9v battery to determine what wires do what if the end has been cut off leaving just the wires

Most radios are fitter with an ISO connector. A universal connector that will alow any aftermartket radio to be easily connected to your cars wiring loom. I.e. you unplug your existing radio and simply connect the new one.

However, quite often you'll need to buy ISO adaptor to interface between the new radio and your car. Unless you fancy cutting and stripping the cables and attempting to manually connect the wires together, but you'll need to know what wire does what and all cars are different...unfortunatley...

You'll need the specific ISO adaptor for your cars, so seek out a specialist car audio dealer for this.

Do you still have the stock connector(s) in the dash?

As I understand you, you have a 4-wire receptacle in the wall and have just acquired a used dryer, that has an older, 3-wire cord attached. You need to change the dryer cord to connect to the existing 4-wire receptacle in the wall. (Dryers sold new, retail do not come with a cord attached so I assume that this must be a used dryer with an existing cord).

If this dryer has a 3-wire cord attached, it MUST be replaced with a newer 4-wire cord, per the National Electrical Code, as you have a 4-wire receptacle. (However I see no reason that you could not use your existing 4-wire cord from your soon-to-be-replaced dryer, if it's still in good shape).

In older dryers, wired with an existing 3-wire cord, there is usually a metal link provided between the center lug (the neutral lug) and a ground connection on the metal chassis. If it's present, this link MUST BE REMOVED WHEN CONNECTING A 4-WIRE CORD. This is very, very, very important.
The reason is, under a fault condition, current could be carried by the neutral conductor (in a 220-volt circuit, the white wire carries the neutral or unbalanced current. There is no neutral in a 120-volt circuit, even though some people think there is).
The presence of this current can be shunted onto the metal frame of the dryer, making it hot to earth ground (until the circuit breaker pops) and providing a possible shock hazard to a person touching the dryer). Removing this link, removes this potential hazard.

When wiring a 4-wire cord, the white wire in connected to the center lug, the two black conductors (could be a black and a red) are connected to either of the lugs on either side of the center lug, and the green conductor is connected to the metal cabinet. (Once you have the metal junction box cover removed from the dryer, you will see a screw driven into the metal cabinet provided to connect the green wire).

Again, when using a 4-wire cord, there must be no connection between the metal cabinet and the neutral connection through the use of a metal link. It must be removed and discarded.

If you look on crutchfield.com or ebay you can find adapters to give your radio a GM plug. You can also buy used GM radios on ebay and at auto recycling yards. Most recyclers have mountains of used radios in their office.

Your new cord has 4 wires. Black, red, white , green.
The dryer has 3 lugs to connect to. Connect the white and green to the center lug, connect the red to left lug and the black to the right lug. You are all set to use dryer.

best buy or most stores that sell new car radios sell wiring adapter kits that simply plug in to your existing harness. It is the easiest way to install an aftermarket radio

look for the thickness of the wires ,or better still buy a ready made connector block that connects to the existing factory wiring
