The EP-1829 is a complete electronic distributor for Cadillac vehicles equipped with the 5.7L V8 engine across the Fleetwood, Brougham, DeVille, and first-generation Escalade platforms. Cadillac's transition from traditional HEI ignition through TBI and EFI systems in the late 1980s and 1990s produced several distinct distributor configurations tied to specific model years and engine management systems. The EP-1829 addresses the most common Cadillac 5.7L V8 distributor applications in this era.
The GM 5.7L V8 used in these Cadillac applications shares the same basic distributor architecture as the Chevrolet and GMC C/K truck applications of the same era, but the exact Cadillac fitment requirements -- connector configuration, cap style, and housing specifications -- require verification against the OEM part number on the existing distributor. The EP-1829 replaces OEM 10458104, 12570425, 93441558, and the aftermarket cross-references 1103952 and 84-1829.
Ships complete with distributor cap and rotor. Compatible with the factory GM ignition module and coil.

Installation guide
Disconnect battery. Mark the position of the distributor rotor and housing alignment before removal. Disconnect the electrical connectors and vacuum advance hose if present. Remove the hold-down clamp and withdraw the old distributor. Lower EP-1829 into position matching your reference marks exactly. Reconnect all electrical connectors. No timing adjustment is required on fuel-injected GM applications of this era -- the PCM controls timing. Verify OEM number on old unit matches EP-1829 cross-references before installing.
