i installed a pioneer deck in my accord ex coupe and i don't have any dash light and weather control knobs lights. everything else/ all lights are fine. i used a wiring harness to connect the pioneer deck. all the fuses are checked by professional and NO BLOWN fuses in both panels and in the engine compartment . However i put my stock radio back in to test it. Still same problem, no lights in dash and instrument panel.

I FORGOT TO DISCONNECT THE -VE while installing the deck

issues after installing the deck
1. no dash light what so ever while the headlight is on. completely dark.

2. only the odometer (very small digital panel on the bottom of the dash) lits up when parking switch is on, and EVERYTHING goes dark when the headlight is on. turn lights, hazard lights, other warning lights come up fine.

3. left side indicator clicking fast and very low power on the bulb. (changed the bulb and seems fine now)
4. check engine light came up after few hours of installthe the new deck. engine light went off right after i put the stock deck in !!!

please let me know if anyone is having the same problems from installing a deck.

thanks in advance.

p.s. All fuses are in working order.
