code reading without a scan tool

i have a 1990 ford f-250 with a 5.0 302. i know it doesnt have an obdII system since its earlier than a 96 but im not that familiar with the obdI system. I know that the connector for it is either under the hood by the master cylinder in that area or some may be under the dash. I want to check my codes by probing the connector but am not sure which pin combonation i need to use. Thx!
