Question about Car Audio & Video
I have a pioneer headunit and a ford corsair 1990. I have bought a wiring harness for the pioneer headunit but was unable to get the attachment for the car side. I have tried to wire it myself but cannot work out which wires go to what. I have found continuity between 2 pairs of wires so i assumed they were the speakers, having the wires with the stripe the negative. However, the wires that go to the battery, the ignition and the earth i am unsure which is which. I found a voltage in 2 of them, so i guessed these were the ignition and battery ones. And i found continuity between 1 wire and the fuse terminals in the fusebox. But am unsure where in the wiring the fusebox would be set up: from the earth, from the ignition or from the battery.. Any help?
This is tough, You need to find one that gives continuity through it when the keys are off, and on. These are the positive wires which is your constant, and accessory. The constant is always powered so when the key is turned off, it's purpose of giving power to the stereo for memory(stations,clock,presets) will work. The accessory as we now know only turns on with the key turned. Finally the ground is a negative, and must not touch the previously mentioned wires. Test for continuity against metal, and probe the suspected ground wire for continuity.
Once these wires are correct, splice them together and the radio will turn on. Now you have the painful process of hooking up one speaker wire,(from stereo) and touching the other wire same color to the other wires in your car to make the speaker work, the more you get the faster it goes as you will weed out incorrect wires since you already have some that work. Once you know a set of 2 wires works for a speaker, make sure it is the correct speaker location, as white and gray are front speakers, and the green and purple are rear speakers. This is longer than knowing the colors, but once completed, you can label the wires and have them known for future technicalities.
sorry your car was not on my wiring list, so no info.
Any questions feel free to ask!
