hi. i'm trying to wire up a new stereo in my 93 accord ex and i've got no power at my stereo harness. i have power to the fuse and the fuse isn't blown. but i don't have power to the harness under the dash where the stereo harness plugs in. i'm assuming i need to trace the wire(s) to find out where i'm losing the power but it's so packed in there that it's a pain in the butt, or i was thinking of running new wires and splicing them to the harness. any ideas, assistance or tips? or images would be great too. thanks!

test from the connector to the fuse block. If no voltage then check at the dash connector plugs. not sure which one it is but its probably on the left side under the dash.

There is not one fuse... Accessory is driver side int box... I am willing to bet it is the 7.5 amp fuse under the hood marked backup that is blown.(constant)Originally posted by hondamikk View Post

wassup fellas i have the same problem going on and i just cannot find a solution i checked all fuese and they are golden.... non are blown i tried 3 diff harnesses but nothing.... what diff will it make trying to hard wire the radio and how do i hard wire it anyway.....Comment

Hard wiring the radio depends on whether or not your radio turns completely off when you push the power button. Basically, you have a few choices
Firstly, your constant power supply to the head unit goes to a constant power supply, either to your battery or to a spare slot in the fusebox.
Second, there is an accessory/on wire in your stereo harness, should be kinda pink colored. That wire has a few options.
1. If your stereo shuts completely off when you hit the power button, run it to the constant power supply with your other power wire. This option requires that you manually shut off your stereo every time you turn the car off and manually turn it on when you turn the car on.
2. No matter what, you can just run this wire to an ignition-based power source, I think there's one in the interior fusebox. Then the stereo will turn on/off whenever this is on.
3. If your stereo goes into a sleep mode rather than an off mode when you push the power button, what I did was ran mine is to a switch, which goes to a constant power source in the fusebox. This allows you to run the stereo with the car on or off.Comment

Have you tryed testing the power line and ground line on the harness?
, id ground the light to the harness's and check, then ground to the chassis and check again. rule out that power is not received to the harness and work backwards from that.Comment

i tested the power lines, yes, but not the ground lines. wouldn't i need a multimeter to test that accurately?Originally posted by Paradien View PostComment

No just use the ground to ground your test light when you test for power.

it just to check the ground wire on the harness isnt faulty. if it isnt then you would have current(light).Originally posted by hondamikk View Post
If you had light when you grounded to the chassis but not the ground on the harness then it ment that that ground was bad.
thats allComment

well, i figured out that my accessory wire has power when the key is turned on and off, so that's a good thing. it's my constant wire that's bugging out. all the fuses are good. i guess i just need to trace the 'hot' wire and find where it's losing power at, unwanted ground or break in the wire or something. any ideas to make it easier to follow the wire?Comment
