I am thinking that I do not need a wiring harness for my Alpine CDA-9884 to go into my 05 Colorado. I have both of the wiring diagrams so I know what all the wires do for what. Can't I just solder the matching wires together and bypass the clip part? Also, I understand that I need a 12v switched power lead so I am going to run the power to a fuse in the fuse box. Anyone know a good fuse to use that runs with switched 12v?Someone please tell me if this is incorrect, but from what I have been reading, it seems as though this is a fine setup. I don't care about losing the door chimes at all.
That'll work fine - and save you a few bucks as well.
You will have to figure out the colors. The wiring harness only costs 10 bucks so it is a lot easier. The colors won't match up to those on the alpine deck. (I tried it once when i got my first car) lol. So the wiring harness makes everything a great and easier experience and cuts the time in half. The 12v for the deck or amp? The deck 12v is on the harness ( yellow). Otherwise run it from the battery if its an amp. The remote wire will shut the amp off.
For the investment of $15-20, you'd be making a big mistake not using an aftermarket harness. For one, if you ever do decide to change radios, you have to do it all over again. Secondly, if you ever decide to sell the automobile, you'd have to sell it with the Alpine, or solder the original harness back in. In which case, the new buyer won't think highly of what you had done. Direct splicing is one of those things that car audio people consider to be a jack-leg move.
