aftermarket stereo wiring, 01 civic

k guys, here's my situation. mind you, i've done tons of search, and got so many different answers, so i am more confused now. the jvc unit's (that i'm planning on installing) wiring that comes out of the unit does not have the blue power wire, and the scosche wiring harness does https://www.cardomain.com/item/SCOHA08B. what do i do about this, and also, will i loose my keyless entree (2001 ex) if i just do this swap, or i do i need this harness instead :

thank you.

ps. i know that the vehicle's power wire is GREEN/ YELLOW, but what good is it if my receiver harness does not have the power wire output. thank you!

You will not lose your keyless entry ( 96 thru 98 only ) and the blue lead only needs to be hooked up if you have an amplified window antenna. You can simply hook it up to the red lead on the stereo and the harness.

The '01 Civic is not weird in this respect. The HU is not integrated into any of the convenience features (dome lite, keyless entry, key buzzer, etc) of the car. I have the same car, and I pulled my OEM HU out just fine.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

k, thanks. there is no antenna on 01 civic, so i'll just leave the "power antenna" hanging then...

No, you missed my point.. If you don't see an antenna on the car that means there is one in the rear window and it is amplified so it needs power. You can remove the right rear "C" pillar and see the small amp there. Make sure the blue wire is powered or your reception will suffer.

i'll just splice it into my remote output (that's going to my amp), since the label on that blue/white wiring coming out of my radio says: " please connect this wire to the remote for the amplifier, equalizer end/or auto antenna. my concern was if it's a safe thing to do, but i don't see why not.

another silly question...what's the best way to connect wires....solder, i will i be fine with some twisting, and electrical tape, or should i get those plastics "twisty caps" lol, sorry don't know their name.

Wire nuts, avoid like the plague. Crimp caps or butt connectors are cheap, sturdy and easy.

thank you.

ps. why are wire nuts so horrible?

They fall off.

If you know how to solder, do that.  it takes 10 min more but proper connection is assured.

do i have to use the soldering paste, or not

also, i've heard that it's not a good idea to twist wires before soldering, but "carefully blend together, so the individual conductors fully reach each other". any take on that?

1: No, the paste is optional. The paste would be used if you are NOT using rosin core solder, which you will be. I have not seen solid solder in YEARS.

2: Way more work than is necessary, and makes soldering look more daunting a job than it really is.

3: Twist 'em. It will make your job much easier, the connection will be physically stronger, and it'll be easier. Did I mention it'd be easier?

4: Here's a really good tutorial... Click the "Soldering 101" link, but the whole page is good information.

The "blending together" action of joining wires you refer to is simply not as strong a connection as twisting.  Strip back enough to easily twist the wires tightly, and solder it.

My ex once told me I have a perfect face for radio.

cool, that's what i was planning...then put some electrical, and hit it with a lighter for a sec, to melt it in.

i ran into a little problem when i started soldering today. i can not seem to get that thin layer on the tip of my iron, it keeps rolling off. cheap solder that came with the iron, or?
