Where is the drl modual for 93 Jeep Wrangler?

A 1993 Jeep Wrangler doesn't have a dedicated DRL (Daytime Running Light) module in the way modern vehicles do. DRLs weren't standard equipment on that model year. If your Jeep has DRLs, they're likely integrated into the existing headlight circuit, or perhaps added as an aftermarket modification. There's no single module to locate. Any control is likely handled by the headlight switch or possibly a relay.
