I have moved and I will have to change my 3 wire pigtail to a 4 wire pigtail. The connector block has three terminals with the following colored wires: LH side Blue and brown; center has a white with a ground strap; the RH side has a black and yellow wire.
To what terminals do I connect the red, white and black 4 wire pigtail? Also, what do I do with the grounding strap?

Re: How to connect a four wire pigtail
The white wire goes to the middle terminal post on the dryer.
The red and black wires go to the outside terminal posts.Doesn't matter which.
The green ground wire needs to be attached to the outside metal case...anywhere. The easiest way is to put the eyelet on the screw that attaches the terminal cover plate when you put it back on. Sandwich it between the screw head, the plate and the case.
Hope that helps. Let me know if you need more info

Its on the side of the block firewall side ... REMOVAL Numbers in text in parenthesis correspond to numbered components in image. Disconnect the wiring harness (1) from the Crankshaft Position (CKP) sensor pigtail. Securely attach a scrap piece of wire about 36 inches long to the CKP sensor pigtail. Later, this piece will be used as a pull wire to guide the new sensor pigtail back through the same routing. Raise and support the vehicle. Remove the oil filter and capture any lost engine oil in a container. Loosen the oil cooler lines at the engine block. Back out the fittings far enough in order to gain sufficient clearance for the sensor pigtail connector to pass between the oil cooler lines and the side of the engine block. Remove the fastening bolt for the CKP sensor (1). Remove the CKP sensor and the O-ring seal from the engine block. Remove the CKP sensor pigtail. Observe the routing of the pigtail. Gently pull the CKP sensor pigtail down through the routing path and out. Guide the pigtail connector along the top of the oil cooler lines around to the side of the engine block. Pass the connector between the lines and the block at the point of the widest gap. Stop when the pull wire is exposed at both ends of the routing path. Disconnect the sensor from the pull wire. INSTALLATION Securely attach the CKP sensor pigtail to the lower end of the pull wire. Pass the pigtail connector between the oil cooler lines and the engine block. Using the pull wire as a guide, pull the sensor pigtail along the top of the oil cooler lines and around to the rear of the engine. Use the pull wire to pull the pigtail into position. Disconnect the pull wire from the sensor pigtail. Connect the sensor pigtail to the harness connector. Thoroughly clean the mating surfaces of the CKP sensor and the engine block. Install the CKP sensor with a new O-ring seal into the engine block. Install the fastening bolt (1) for the CKP sensor. Check the harness for proper routing. Make sure that the wiring cannot come in contact with the exhaust manifold. Tighten the oil cooler lines at the engine block. Install the oil filter. Lower the vehicle. Recheck the engine oil level.
Yes, you surely can! Here's how. When you open up the back of the machine where the electric cord attaches, you will see a row of 3 screws/bolts. Your 4 wire cord has the black wire going to one of those screw/bolts. That is a HOT connection. Your cord also has a red wire attached to a screw/bolt. It too is HOT. These two hot connections are the outside two of the row of three screws/bolts. The one in the middle is a ground wire, and is white. The other, the fourth wire, usually blue or green, it is attached directly to the sheet metal of the dryer itself. It too is ground..
Now, the 3 wire cord is not color coded, it is "position" coded. The two outside wires go to the outside (in the row of 3) screw/bolts of the dryer. the middle wire is hooked to the middle ground screw. It doesn't matter whether the outside wires go to the right screw or the left screw, but never to the middle screw. By the same token, never hook the middle wire to an outside screw/bolt. You will have no fourth wire going to the sheet metal. Be blessed.
Connect the three-prong wire you have the way the same wires (Line 1, Neutral, and Line 2) of the four-prong wires are connected to the terminal block then connect the integrated grounding strap to the Neutral (center) terminal.
To change from a three to a four wire cord you will need to remove the ground wire/strap that is currently connected to the center connection at the back of the dryer. This ground wire is going to look like a flat piece of either copper or aluminum that connects to the center peg and is screwed to the dyer cabinet right next to the cord terminal block SAVE THE SCREW. Doing this separates the electrical neutral and the cabinet ground.
Now when connecting the four wire cord, put the red and black wires on the outer connection posts (does not matter which goes on which side) and the white neutral wire connects to the center connector. The green or sometimes green with yellow stripe wire from the cord will connect to the cabinet where the ground strap you removed used to connect use the same screw that you removed earlier.
The wires on a flat 3 prong pigtail go on just as they are. The center wire goes on the center post. The outer wires go on the outer posts. The wires do NOT crossover at all and it doesn't matter with the outer wires. Just as long as the center wire is on the center post. You *must* put a ground strap from the center post to the case. It should have been removed or disconnected when the 4 wire pigtail installed. If you have a round 3 wire pigtail, the White wire goes to the center post. Red or black to either outer post.
WHy are you switching the cord from a 3 to a 4? If the dryer came with a 3 prong cord and its a 3 prong terminal block, then i dont think you can change it to a 4 becuase you will short circuit. DOes the terminal block where your cord was hooked up have 4 terminals. Each termial can only have one lead/wire to it. check your circiut breaker panel? Is the circiut breaker tripped?
to put it kindly depending on way you connected wires unit could be damaged,replace pigtail with three wire and outlet to original.outlet wires should be black,red and white. turn breaker off attach white to middle and red,black to sides,"either side is fine".Attach dryer pigtail in same manner with white on white and if plug in and turn breaker on.If there is no operation at this point dryer possibly damaged from previous wiring.Just remember be safe when working with electrical and ask before trying to change things that aren't the same.
get another electrician, he doesn't know what he is doing, this is not easy to figure out without diagrams of the connector that shows exact wire colors and where they go or went in prev installation..
A three wire pigtail is connected thusly. The two outer wires go to the two outer terminals on the dryer, the center lead goes to the center of the dryer terminal block. If its a four wire pigtail, the outer leads go to the two outer terminals on the dryer, the white goes to the center terminal. The jumper strap on the center is removed and the green goes to chassis ground.
