Here is a link that shows how to pull the codes: EEC IV Self Test hookup . You can leave out the voltmeter/test light and simply watch the check engine light blink.

To set the timing correctly, you need to pull what's called the SPOUT (SPark OUTput) connector, which will disable the computer advance. The SPOUT connector on your 88 will be near the distributor.
