Ignition Control Module for OE-Style Repair

Standard Ignition LX-371 is an external ignition control module built for 12-volt systems and direct bolt-on mounting. It is engineered for vehicles that need a dependable replacement module with stable coil control, strong heat management, and reliable operation in demanding underhood conditions.

Key Features

• Bolt-on attachment method for straightforward replacement
• Female 7-pin connector with 19 male blade terminals
• External mounting location for OE-style service applications
• 12-volt ignition control module design
• Copper slug heat sinks for improved heat dissipation
• High-temperature polymer housing to reduce moisture intrusion and vibration damage
• Built to respond to weak crankshaft position sensor signals for quicker coil energizing in cold starts
• Durability tested through 500 thermal cycles from -40C to +125C

Detailed Description

The Standard Ignition LX-371 ignition control module is designed for vehicles that rely on precise electronic ignition control. Its construction focuses on connection integrity, thermal stability, and resistance to vibration, which are important in older ignition systems where module failure can cause drivability problems. This part is a practical replacement for applications such as 1986-1987 Oldsmobile Calais, 1986 Buick LeSabre, and 1986 Oldsmobile Delta 88, as well as 1986 Pontiac Grand Am and 1986 Buick Skylark applications listed in the fitment data. This part cross-references AC Delco (e.g., 6H1042, 55-1542) for the same application.

What It Helps Resolve

• No-start or hard-start conditions related to ignition module failure
• Intermittent spark loss or weak ignition output
• Cold-weather starting issues tied to delayed coil energizing
• Heat-related module breakdown from repeated thermal cycling
• Vibration-related connection or housing damage

Installation Notes and Tips

Verify connector style, terminal count, and external mounting location before installation. Confirm the vehicle uses a 12-volt ignition system and compare the original module dimensions and connector layout to the LX-371. Fitment includes 1985 Buick Century, 1985 Oldsmobile 98, 1985 Oldsmobile Calais, 1985 Oldsmobile Cutlass Ciera, and 1985 Pontiac Grand Am, with a note that some 1985 Buick Century and 1985 Oldsmobile 98 applications are not compatible with distributor setups. For 1986 Buick LeSabre, 1986 Oldsmobile Delta 88, and 1986 Pontiac Grand Am, the listed application is Ignition Control Module - 6 1/2 Inch.

Quality Assurance

Standard Ignition applies electronic ignition manufacturing expertise and controls quality from component selection through final assembly. The LX-371 is built with double wire bonds, copper slug heat sinks, and a high-temperature polymer housing to support dependable service in harsh operating conditions.
