Wiring Harness 1989 Volvo 240 DL

OK, calm down, take a couple of deep breaths. If your stereo was somehow devoid of any "harness" which ends in a molded connector - either squarish white plastic or rectangular and black, plugged into the back of the stereo - then it's an oddball, but so be it. Your old stereo had power and ground going to it, and speaker wires coming out of it. Those wires all still exist, they're just shorter than they were before you cut them. Not a biggie. The biggest task ahead of you right now is to identify which wire is which, and you really need a meter to sort them out. If you don't have one, borrow one or get a $25 one from Radio Shack... it's worth it in the long run. To identify the speaker wires correctly, pop the grilles off the speakers and unscrew them so you have access to the wires. The speakers are typically marked + and - (you may have to look closely). Just clip one test lead to one of the speaker leads and then, using the 'continuity' feature on the meter, check each of the wires in the bundle which you cut in the dash. Do this for each speaker. Then find your ground wire, checking between a good ground (like the ignition switch) and the remaining non-speaker wires. Lastly, figure out which lead is hot (+12v) with the ignition off, and which is hot with the ignition on. If you have a power antenna, then you'll probably have one wire left over, and that's what it's for. Now of course as you've identified each wire you've also marked it with a piece of masking tape labelled appropriately. At this point you are now prepared to do battle with your new stereo's wiring. To make life simple you might want to invest in a crimping tool and use quick-connects, otherwise you really should solder your wiring connections. The least desireable method is to twist wires together and use wire nuts or electrical tape to keep them together.

Good luck... you *will* get thru it, just be patient with yourself. Get all the wires identified, then if you're still stumped, ask more questions.
