You do that by going to a proper stereo outlet. They carry a kit for your specific year (88), the wires are color coded in the kit to match the colored wires in the other harness that I mentioned (there are approx 5 or 6 different colored wires; you just splice them together.

Use proper wire connectors and crimp them, don't do a hack job with tape. Your correct ... on your 88 the amp has to go like you mentioned because the newer stereos have the pre amp built in.
Yeah I do a pretty good job with tape but after some years it won't be so good lol I'll buy some crimps. I think i'll save this for the weekend, but I think I understand what you're saying. I basically have to splice the amp harness to the stereo harness to the aftermarket stereo harness.
