problem with ford stereo install

im having trouble intsalling a new jvc stereo into my 92 sierra

basically, the colours of the wires are not the same as the stereo, it hasnt got any info in the manual, i cant find any online and im completly stuck

i dont really wanna have to buy a maunal for a stereo im not going to use so i was wondering if anybody knew which colours you attach for power etc

Did you use a wiring harness or did you hardwire it.

If you hardwired it, it could be a number of things, but most obviously, it might be that you connected wires to the wrong spot. Theres an FAQ here on the12volt.com that shows what the colors of the stock wires mean.

If you used a harness, try taking it back to the place you bought it and ask them if there were ever any compications with HU installs on your model and year of truck. The Harness WILL come with directions as to what wire to connect where, and aftermarket HUs will also show it in the manual.

Try this;

Oh, that could change things then.

I'd say your best bet is go to any place that installs stereos and ask for an Aftermarket Headunit Wire Harness, or if need be, order one online, from Crutchfield.com (i'm not sure if they ship to the UK)

Then all you'd do is match the harness color wires to the HU wire colrs,plug the clip into your truck's factory clip and you're done. Took me about 30 minutes the first time.

I saw that too and thought it was a typo, for us here in North America, a Sierra is a GM pickup. (ewwww) Ford forever (I know you F350 fans will agree) Have you already cut the wires off of the factory plug? If you have not, take a look at this site to see if the wire molex in your car looks the same as the ones listed on the site. Look in particular for the Ford vehicles applicable to your year. If the plugs look the same but the wiring colors are different, you have a place to satrt.
