12V plug blowing fuses
Bought a '93 Civic DX with a D16Y7 swapped in for $800 with only minor issues. Current issue I'm tackling is the 12V plug. It was rusted out so I bought a new one and installed it. Now it's blowing fuses left and right. Left it uninstalled for now so I can use my new head unit (it had a dead OEM unit). My phone could really use a good charger so what could be going wrong? Can provide pics if necessary.

I go out and get a pic of the fusebox. Temporarily using a higher rated fuse and will be getting the proper one tomorrow. It blows only when the 12V is installed and immediately when I turn the key to accessory.

It's the yellow 20 fuse. Ran out of 15s because of this problem.

Re: 12V plug blowing fuses
sounds like a short. OP I would verify that the wires running to the plug are not touching each other, also, make sure any connections or joined wires have heat shrink or insulated connectors around them.

Re: 12V plug blowing fuses
The hot wire for the cigarette lighter should be Yel/Red, which is missing in your picture. Please clarify.
In addition, you have spliced a white plug to the modified wires. This extra plug has a Wht/Blu wire, which looks burned. This burning suggests the location of the short that is blowing fuse 23.

Re: 12V plug blowing fuses
Do you use or plan to use both the white plug and the cigarette lighter plug?
Not sure because I can't see both ends of the Red/Blk and Blk wires, but the plugs appear to be connected in series, which is unusual. Can you post additional pictures that make the wires more visible?

Re: 12V plug blowing fuses
I suspect that whole setup was custom rigged by the previous owner.
If you install a new fuse into the 23 slot with that set up in your picture left unplugged, does fuse 23 no longer blow?
Also, can you post a picture of the male plug that connects to the plug in the setup and also show its wire colors?

Re: 12V plug blowing fuses
Yes^
Okay. I see the problem. The previous owner rigged the added light to share ground with the cigarette lighter. That won't work.
Spliced into the Blk wire between the bulb and white plug is a metal female connector that was connected to the cigarette lighter. Remove that metal female connector. The splice/shrink wrap the Blk wire at that point. Save the removed connector.

Re: 12V plug blowing fuses
Solder the removed metal female connector to a fresh separate Blk ground. Plug the metal female connector into its original male connector on the cigarette lighter. Either find a screw in the metal frame under the dash to ground the other end of the Blk wire or drill a hole in the metal frame to add a screw to affix the Blk wire.
Now the light and cigarette lighter should both work.

Re: 12V plug blowing fuses
See added text in my previous post. Keep the light as it probably was illuminating something in a different location originally. Try to find its original home.

Re: 12V plug blowing fuses
1) What do you want to use the orange wire for? Does the orange wire connect to a Red/Blk wire in the Civic wire harness? If so, that's a hot wire.
2) It looks like the bulb in your picture is actually stock for the Civic cigarette lighter. Does it work? If so, does it dim and brighten with the dimmer switch or is it constant full bright?

Re: 12V plug blowing fuses
We have light! It's constant bright, no dimming.

And here is where I placed the new ground. Haven't plugged in the 12V plug yet. Hope it doesn't blow another fuse.

Re: 12V plug blowing fuses
Not sure but I may see another potential issue. See diagram below. In post #6, the Wht/Blu wire may not be connected correctly. Shouldn't it attach to the nearest male prong below?
The orange ground wire should attach to the lower side prong where the Blk wire was connected.

Re: 12V plug blowing fuses
It's the only place it can fit, as the other places are too large. The grounds are officially separated. Fuse still blew. Unplugged the white/blue and installed a new fuse and it's functional again.
