Car Forum / Driving, Maintenance, Tuning / Car Audio / January 2007Ignition/Constant Problem
Hey, So I just recently got a Pioneer deck after living a long 3 months with a low grade Sony deck. Ive had a problem with both of the decks though with the Constant and Ignition wires. I hook everything up, color to color, for both harnesses, plug it in, nothing happens. I connect the Constant and ACC together on both harnesses, connect with a butt connecter, and wha-la it turns on. Seems all great until I turn the car off. Turn the car back on, everything is reset. I've heard that I would have to wire the ACC to the fuse box, but I was just wondering if there are any better solutions. thanks, Mark > I've heard that I would > have to wire the ACC to the fuse box, but I was just wondering if there > are any better solutions. The fuse box is probably the worst place you could go to get power in an automobile--poor connections and lots of noise to be had there. It'll work for you, no doubt, but if you have the time and inclination, you'd be better off running a wire direct to the battery--just make sure you fuse it at the battery and go through an existing grommet or rubber boot when going through the firewall. A 14AWG wire would do you well, especially if you're using the onboard amp (i.e. the speaker outs on the head unit and not an external amplifier). -dan Where do you think the factory harness is fed from if not the fuse box? even with that said the ACC wire does not feed nothing other then the memory. The amp is fed off the switched wire. >> I've heard that I would >> have to wire the ACC to the fuse box, but I was just wondering if there [quoted text clipped - 10 lines] > >-dan Hey, Does your cigarette lighter work with the key off, or does the car have a clock? Any off those will do.

It's a 93' Honda Civic. When I had the stock deck in (tape deck) i had no problems with the radio presets being reset but once i put in an aftermarket cd player thats when I had the problem. I was actually thinking today of connecting the ACC to the cigarette lighter because its only works when the car is on. How would I go about connecting that to the lighter. I looked at it the other day and there's about 3-4 wires that go into it through a clip. That wont help you then , because you need the cigarette lighter to work when the car is off. Lets make sure that you have the right wire hooked up, Constant 12V+ = White/Blue on the radio harness. If that seems fine, but not working you can wire your constant 12V+ off the 'Ignition Switch Harness', the wire you will need is white. You also have the option of tapping onto the glovebox light if you have one. >It's a 93' Honda Civic.

The fuse box is near the battery Im confused now though. If my deck resets everytime i start the car would it be a problem with the constant or the ignition, to get the deck to work I had to twist the constant and ignition on both the harnesses and then connect them with a butt connector. I also have a small tachometer that is hooked up, could I use wire's running off of that? Also even though the light burnt out there is a light in the ashtray but I dont know if it was always on or only when ignition. > Im confused now though.

If the constant fuse is bad your clock will reset and your presets will reset. The units needs the constant to remember the presets and keep the clock running while the car is off Your ashtray light should only turn on with your parking/head lights NO GOOD. >Im confused now though.

The only idea I currently have is that i could splice the constant to connect to the dome light wires. If only I knew where the wires where? Or could i just run it from the deck to the battery. My hole through the firewall is really close to where the deck is so it wouldnt require too much wire. The dome light is not a good idea, running it to the battery will do just fine. make sure that you fuse the wire at the battery. 3 or a 5 amp fuse will do. >The only idea I currently have is that i could splice the constant to >connect to the dome light wires.
