you should splice the yellow and red wire together and touch that to the positive and the black to the negative.

Alrighty, I'mma go blow myself up. I'll update this if I still have fingers. :P

I was going to suggest you hook it up to speakers as well, but I realized you don't need speakers to see if you have an E20 error message. I guess that'* why I try not to give audio advice.

I thought the exact same thing when hooking it up to a battery was first suggested, so no worries.

I'm curious about this, though: I don't disconnect the wire harness from my car when I remove the radio. Does this mean I need to disconnect my battery, crawl in the to dash and remove my harness?

I don't have a spare, although I was looking into buying a new one earlier. Think I should and use that to test, then place it in the car if it proves the radio works?

The wires just came in and wouldn't you know it, they don't fit.

I quit. I'll listen to the radio.

i have a 1999 camaro z28 radio has a error in the cd payer will not pay anything

Fix for error code E20

Error code E20 occurs when the CD'* laser can't focus due to a dirty lens.

My 2002 Pontiac Firebird Trans Am'* Monsoon CD would only play commercially made CDs. It used to play CDs I made at home with my desktop but suddenly stopped playing them altogether and an error code E20 would be displayed before ejecting the CD. This is because CD players have a harder time reading privately made CDs, and my CD'* lens hadn't been cleaned since I bought the car 11 years ago in 2002 .

I removed the Monsoon from the dashboard, removed the case, motherboard, control board and last of all the CD player. Once removed, access to the CD'* lens was easy. I cleaned it with isopropyl alcohol (rubbing, NOT drinking, alcohol) and a cotton swab, or Q-tip. After reassembling everything, the Monsoon plays any audio CD once again and no error codes.

pro - $500 savings to replace, or do without privately made CD'*
con - 2 hours to do
