So i went to replace a head unit on my 2002 crv, and i connected the negative cable to the battery and then the positive.

Now the odometer doesnt display a number unless the car is on (was this standard operation or did i screw something up), and the light is very dim. Also in the shift lights, D is no longer illuminated.

Do i need new bulbs or is there another solution?

Try this procedure from an older Service News article:

Erratic Gauges or Odd Odometer Display? Reset the Gauge Control
Module


If the gauge needles are bouncing around or the odometer display is blank or displays nonsense, try resetting the gauge
control module. Here’s how:
1. Make sure you have the anti-theft code for the audio unit and the navigation system (if equipped), then write down
your customer’s audio unit presets.
2. Disconnect the battery cables, starting with the negative cable.
3. Touch the battery cable ends together for about 1 minute.
4. Reconnect the battery cables, starting with the positive cable.
5. Start the engine, and watch the gauge assembly.
• If the gauges or odometer still don’t work right, shut off the engine, and do the self-diagnostic procedure in
the applicable electronic service manual. Then go to step 6.
• If the gauges and odometer work OK, shut off the engine, and go to step 6.
6. Do the idle learn procedure:
• Make sure all electrical items (A/C, audio unit, defogger, lights, etc.) are turned off, then start the engine.
• Let the engine reach its normal operating temperature (the cooling fans cycle twice).
• Let the engine idle (throttle fully closed and with all electrical items turned off) for 10 minutes. Shut off the engine.
7. Initialize the driver’s window auto-up feature (if applicable):
• Turn the ignition switch to ON (II).
• Make sure the driver’s window is fully closed.
• Push down and hold the window switch. Make sure the window goes all the way down.
• Pull back and hold the window switch. Make sure the window goes all the way up,
then hold the switch for at least 2 more seconds.
8. Enter the anti-theft code for the audio unit and the navigation system (if equipped). Enter your customer’s audio unit
presets. Set the clock.

Keep us updated,

Cheers!

Welcome to the forum! After you get this sorted out, go over to the Mobile Electronics Section and tell us all about your new head unit install! Preferably with pictures!
