Usually Sony EQ's have a square, 4-pin connector on the back of them

If your looking at the back of the EQ, the upper left pin is +12V (power), the upper right is the Remote, the lower left it Ground, and the lower right is usually not used, but can sometimes be the Illumination circuit... but again, usually is not used.

4-prong to 3-prong Power Cord Conversion.

On a 4-prong power cord you have 2 hot wires, one neutral wire, and one ground wire. On a three prong cord, you have 2 hot wires and one neutral/ground wire. The difference is the on four prong the neutral wire goes to electrical neutral bus in the breaker panel and the ground wire goes to the ground bus in the breaker panel. Since the neutral and ground buses, although separate, both go to physical ground, on a three-wire setup, you are just putting the neutral and ground wire together, Most dryers actually have a place at the pigtail connection to do just that.

New house has three prong recpticle dryer cord has four prongs. Can I use a three prong cord and strap a wire to the fourth wire on back of dryer? If not got a solution?

If the new house has an existing three-wire outlet, the simplest solution is to install a 3-prong power cord on your dryer. The following link explains the differences between a 3-wire and 4-wire configuraiton:

So...if you need to install a 3 prong power cord, it should be wired as follows:

WHITE (NEUTRAL) 0 VAC to WHITE - a Ground wire needs to be connected to the Neutral lead at the terminal block and grounded to the dryer cabinet.

The other alternative would require you to install a 4-wire receptacle so you could still use your current power cord. A certified electrician is recommended for this job and may cost you some money. A replacement power cord, on the other hand, usually costs less than $20 and can be found ay any hardware store.

If you have any questions, please post back and let me know. I hope you find this information helpful.

How do i connect the wires on my GE dryer from a 3 prong to a 4 prong withour the gterminal block? My terminal block is missing.

The following link explains how to properly convert a 3-prong power cord to a 4-prong:

The main difference is how the Neutral and Ground wires are terminated. In a 4-wire configuration, the Ground and Neutral are INDEPENDENT of each and are NOT terminated together.

Match the correcsponding wire colors at the terminal block and make sure the grounding strap (if installed)on the Neutral (White) terminal is removed. The ground wire will be connected separately to a ground lug on the equipment cabinet.

NOTE: If the wires are not color coded, the outer two wires (left and right) are the HOT leads. The center conductor is Neutral.

If you have any questions, please post back and let me know. I hope this helps you.

I have a three prong plug in connected to my dryer and need to connect a four prong one but dont know which wire is which.

The following link explains step-by-step how to install a power cord to your appliance:

The main difference in these two configurations is how the Ground wire (GREEN or BARE COPPER) and Neutral (WHITE) wires are terminated at the terminal block on the back of the dryer. In a 3-wire configuration Ground and Neutral are connected together via strapping option. In a 4-wire configuration these two wires are independent of each other and are not terminated together.

Read through the link provided and let me know if you have any questions. I hope this helps you.

These two pictures illustrate the power wiring on a the terminal of an electric dryer. The one to the left here is the old-style three-wire configuration. Most people have this type in their homes. New code changes, though, require that dryers now have a four-wire cord, shown to the right. These are just just thumbnail pictures that you can click for a larger view. But I'll bet you already figured that out, didn't you?
Besides the number of wires in each cord, there are two important things to notice. First, in the four-wire configuration, notice that the dryer's grounding strap is folded back on itself. The whole point of the four-wire cord is to separate the ground from the neutral. The green wire (the "new" extra wire in the four-wire cord) is attached to the dryer cabinet. In the three-wire configuration, the grounding strap is left intact and the neutral and ground are tied together.

Sure hope this helps you find a resolution to your delimma! Best wishes.

Wrong power chord I need to change from 3 prong to 4 prong.

The following link describes how to convert from a 3-prong appliance cord to a 4-prong:

The difference is the way the Neutral (White wire) is configured. On a 4 wire configuration, the neutral is independent of the ground (Green) wire. Which means you DO NOT ground the white wire. Ground gets attached to the equipment cabinet or appropriate ground lug.

NOTE: This is for United States standard wire code. If you live outside the US, your wire color coding will differ. Please let me know if this is the case.

Let me know if you have any questions. I hope this helps you.

I had to change from a three prong to a four prong outlet. The green wire wont reach the gound bolt on the back of the dryer. I currently have it set on top of the white wire but there is also a copper...

You need to remove the grounding strap between the GROUND (Green) and NEUTRAL (White) wire if it still attached. A four prong configuration has a ground independent of the neutral wire. If the ground wire is too short to reach the terminal block, I suggest you install a longer wire of the same gauge, find an alternate location that you ground the wire to the case, or pig tail the exisiting ground to accomodate. The following link explains the 4-prong configuration:

Nearly all modern appliances require a 4 prong power cord now. If you have any questions about this repair, please let me know. I hope this helps you.

How do i turn on sub mode?

For one thing I hope you know you need an amp to even power subs at all.. The remote wire coming off the rca wiring that you hook your subs up with has to go on the prong 3-in on the top here is a rough diagram: the = signs are power and ground and the prongs are thicker the comma is you remote..
- - - - - - - , - =
- - - - - - - - - =

You need a wire coming out of that slot on the wiring harness.. it should be blue. and unless you have a power antenna(comes out when you turn your radio on) then you dont need the blue/blue&white power ant. wire you can just cut it and cap it. if your amp isn't coming on when you turn your ignition to acc then your remote wire isn't properly attached..
