MPH GAGE and power loss to stereo

Recently we purchased a 2004 Jeep Liberty 4x4. The check engine light came on and we diconnected the positive on the battery it went away. Right after we plugged it back up we tried to install a jvc radio which we decided when it wasn't working maybe we needed to also get some other connectors for it mind you we lifted ebrake to do this as well. When plugging stock radio back up none of the radio parts work and neither does my rear defrost. After all of this the next day I noticed my mph gage stopped working. Can anyone tell us what we need to get and how to fix this my husband and I usually try to fix things on our own unless too complicated then we take it to the shop. Thanks in advance !

2004 Jeep

Hi, ERCJCC; It is very possible that you've blown a fuse. Check any fuses under the dash and the main power box under the hood. Otherwise, sounds like you've disturbed a connection while swapping stereos?
Good luck.

Fuses

Thanks Loren, we tried checking fuses but I think it may be more of a ground wire problem just can't seem to figure out how to fix it. I appreciate you taking the time to help us figure it out.

Fuses

Hi, ERCJCC; Not sure how you are 'checking' the fuses. I like to use a 12V test light by touching both sides of the fuse. Some fuses are only 'hot' with the ignition on. You should have power to both sides of the fuse. If only one side is hot, then you've either a blown fuse or a problem with that particular circuit. (Keep in mind that some will have no power on either side unless that circuit is in use, like headlight circuit). Most public libraries have wiring diagrams that you can print out that will also show ground points. I'm really suspecting that something in the dash was disturbed. Check the connection (wiring plug) going the back of the instrument cluster, as well as any other plugs.
