2004 envoy base I spliced the radio harness. Trying to hook up a aftermarket radio what's the color code and why is there two orange wires if the power is orange witch one is

This is why walmart and others sell a wiring kit that plugs one end into the stock wires and the other to your radio, One hot ware goes to always hot wire for clock and station presets, other goes to switched ignition so radio goes off with the key.

Alternator wire diagram

I'm afraid not. The alternators as well as the trucks are wired differently.
The black yellow wire on both models goes to the fuse box, but on the 2005 model with the extra wire, the gray orange and brown white wires goe to the engine computer which acts as the voltage regulator. The 2003 computer would not have provisions for those circuits.

How do you remove a transmission from a 1994 plymouth acclaim?

If this is front wheel drive (most likely is; will have drive axles in front leading toward engine and tranny).

1. Raise and secure the front of vehicle on stands, and drain tranny fluid into a pan or bucket.

2. Remove tire and tranny side drive axle.

3. Disconnect all components connected to transmission (shifter cable) and any sensors, wires or wiring harnesses.

4. With a jack secure the transmission from underneath. (do not jack up tranny, merely put a very slight pressure to hold in place)

5. take out all transmission bolts that securet the transmission to the block (engine). If there is enough room, slowly lower the jack (another person secures transmission from top (keeping it balanced), and pull the transmission out. Be careful that the torque converter does not fall - it is heavy and may come out with transmission. (usually bolted to flywheel, also known as flexplate). This will have fluid as well in it, and will need to be drained (most of it).

Installation is reverse; also, if no room to drop tranny, two people can easily lift it from the top. (Cherry picker recommended.)

Please let me know if you need further assistance.

are you getting codes for incorrect gear ratio and shift solenoids? if so then you are in need of a complete transmission overhaul.
However before you do that, check on the drivers side of the engine compartment under the battery tray is a wiring harness that runs next to the transmission, after a leaky battery and years of service, the pink wire that goes from the tranny control module, on the passengers fender, to the tranny gets corroded and brakes inside the insulation, check powers and grounds and if all is ok then bring it to a tranny shop, the sun gear brakes alot in those units, had the same problem on my cousins 3.3L and had to do an overhaul.
sorry to be the bearer of bad news.
