I created this in the hope that a sort of "wiring 101" guide could be on hand to everyone including noobs like myself. So please ask basic worrying questions here and then i can consolidate the guidance at the top after a while. I've got since questions to start off with: If i have multiple components to setup in the car can i connect them all to the same power line or should they be connected to different power wires that take power from different power sources (fuse box, directly from battery, etc)? Can i take power from a fuse on the fuse box or should it be directly from the battery? When taking power from a source should i also connect a fuse to the line first? And should it be the same fuse as the line output or the power draw from the component? (Hard wiring usb components that have a step down transformer from 12v to 5v for example) What are relays and should i be using them or how do i know if my scenario requires one or not? Are particular wire connecting devices recommended (list some links to good ones please) or should i just splice and twist new wires to one another then cover in electrical tape? Is there a rough limit on how many components i add to my car, or, how do i know when i need to connect a second battery to the power system to balance the load? There may be more questions, or concerns that arise but answering these works really help me figure things out for now.

Thanks Pete

Does anyone know if it is the same wires for the mk2 fabia also? i connected a rear backup camera to these colours and it worked for a while but now I can't get it to work , nor my rear wiper. I wouldn't be surprised if I've done something wrong, can anyone advise on this please?

That was unnecessary. This is supposed to be a forum where people help one another, not a place to mock people. I am a noob, and yes i saw various things on the bulk head but had no idea where they would lead to on the inside and how to access them from the inside. And i don't want to start drilling holes all over the place in the hope that one is going to work. If i had a car geek mate available i wouldn't have needed to ask for advice. It's great that you think this is all easy stuff but i don't know the first thing about what I'm doing and don't want to get it wrong. Go easy.

Thanks that's really helpful. The second location you mention is on the drivers side and then you say about the bonnet release grommet. So i will have to get the cable from one side of the car over to the other side right? (And do it blind as to knowing where the cable is traveling exactly). Is this a lot easier in practice than it sounds in my mind? (I'm a noob and expecting to mess it up). Doing it this way will also mean i don't have to take the dashboard off etc?

I've just wasted an afternoon trying to install my Kenwood SW11 subwoofer. I tried to figure out how to get a power line from the engine bay through to my subwoofer but I can't find a grommet or know where to drill a hole into the interior safely. The engine bay is crammed with stuff so there aren't many areas open to put a hole from. I tried removing the glove box before seeing that it is part of the dashboard. removing the whole dashboard seems ridiculous to just get a hole through. The sub will be installed via RCA cables to my pioneer sph-250dab stereo and comes with two cables for power. one is blue, for the included remotes power. the other is yellow and for the sub’s power (with a fuse on it). there is also a black grounding cable. Can anyone tell me how to get through this freakin firewall easily and safely, please? (preferably with images of where to make the hole or find an existing hole, etc). Could I not just connect the sub power cable to my interior fuse box (ignition fuse)? And the ground to a screw near the fuse box? I think the remote power could also connect with the sub power?

well/ i've been looking online for ages now and it seems the only two controllers that pioneer do (sr110 and sr100) are crap and rely on direct infrared control which (looking at all the bead reviews) is just a bad design in the first place. What is the point of even making them if they don't work well at all(!?). anyway, it looks like my only options are buying a 2nd hand steering wheel with the controls builtin or try to find a bluetooth controller that be mounted on the steering wheel and controls my phone, not the stereo. It's shocking how crap the aftermarket options are unless you already have steering wheel controls.. really can't see why no company has risen to the challenge. i doubt it is that hard. the other option is to get a steering controller designed to work with an app that you install on an (android) stereo but I'm not sure if it is possible to install apps on this stereo (or even many branded stereos)???

Thanks for the reply. I've actually ordered the fitting kit now. All i need is a string wheel controller too connect to it lol. Either that or some kind of Bluetooth based version. I've seen some in Amazon but not sure if they are compatible. Any ideas/recommendations please?

i found this remote control but it isn't compatible with my car https://www.amazon.co.uk/Pioneer-CD-SR110-Steering-Control-Bluetooth/dp/B000N9FJ0Y/ref=sr_1_12?dchild=1&keywords=Steering+wheel+control+button+kit+for+car+stereo+pioneer&pd_rd_r=0bd4a0e6-7dc6-43be-97a3-77fb4110d105&pd_rd_w=aDUwP&pd_rd_wg=QJFgn&pf_rd_p=ddb42f12-1399-44e9-b255-a04cb915f897&pf_rd_r=231XZKPX7KPF9SMRTR54&pid=1koBLgt&qid=1611078146&sr=1-12&vehicle=106-1341-6363-33243--0&vehicleName=Skoda+Fabia+Hatchback+1.2+TSI not sure if this one is compatible? https://www.amazon.co.uk/Pioneer-CD-R320-Remote-Control-Tuners/dp/B0011ECEHG/ref=psdc_3013843031_t2_B000N9FJ0Y anyone got suggestions? some time this month even? (I'm getting impatient with waiting to get it all fitted lol)

As the title suggests. I've had the stereo delivered. Now i need to purchase the correct parts to fit it. I would also like to purchase a string wheel controller and the appropriate fitting kit or whatever it is that i need. Can anyone provide actual item links because I've been searching for the last week and still aren't sure I'm finding the right parts lol. Cheers guys, Ste
