ACDelco Gold ignition control modules are a high-quality replacement for many vehicles on the road today. They increase the voltage in order for the spark plugs to ignite the air/fuel mixture. The modules feature electronically welded lead connections to help reduce heat stress, failure, or cold joints; and they've been laser-trimmed to provide precise values and reduce deterioration and damage. Gold ignition modules include a copper slug heat sink to help dissipate heat and create a more stable environment. They also feature a large bus bar for added support and conductivity to address the installation and operating forces that stress terminal tabs. Order the model recommended for your application.

When your classic isn't shifting properly, Scott Drake vacuum modulators could help. These automatic transmission pieces are a vital component that tells the transmission what kind of load is being put on it, allowing it to react with the proper line pressures and shift points. They are offered to fit directly in the factory location of the current throttle valve in many Ford classics. Improve the performance of your transmission with new Scott Drake vacuum modulators.

Vacuum modulators are designed to tell your transmission what kind of load is being put on it and react with the proper line pressures and shift points. Over time, these modulators can develop leaks or get damaged, causing driving issues and even premature transmission failure. TCI solves this dilemma with these adjustable modulators. Not only do these modulators renew performance, but you will also have the ability to slightly raise/lower part throttle shift points and line pressures. Simply adjust the screw inside of the vacuum nipple for more or less diaphragm preload.

The Diode Dynamics S1 Switchback modules are a 12 V LED switchback controller in a waterproof, low-cost package! With an input range of 9-16 V and common ground, they are perfect for any automotive application, and they can be used for turn signal applications, DRLs, and more! Features: * Waterproof and shockproof, with full encapsulation * 12 V application * Used for turn signal and DRL functions * Turns lights into DRLs or turn signals * A maximum current of 2 amps on the white channel, and 3 amps on the amber channel * Male Spade Connectors with T-Taps for installation * 3-wire set up for Ground, White DRL and Amber turn signals * Perfect for the retrofitter or do-it-yourselfer looking to create an OEM-style function with a few 12 V LEDs * Designed and assembled in the USA by Diode Dynamics Manufacturing Input: All input wires are male spade connectors with T-taps for installation—there are three wires for input: black, yellow, and white. -- Black: Ground wire which should be connected to a constant chassis ground -- White: Static wire or running light input -- Yellow: Turn signal input—this will also shut off the static output, so it could be treated as a shutoff wire for DRL applications Output: All output wires are bare leads for connection to LEDs. There are three wires for output: black, yellow, and white. -- Black: Extra ground output—this does not need to be connected as it is an extra ground point, you can connect LEDs to ground here, or anywhere on the chassis -- White: Static output—when power is applied to static, and the turn signal is not activated, and it will output 12 V of power—for example, you might connect this to a white light to act as a running light -- Yellow: Turn signal output—you might connect this to an amber or red LED to become a turn signal—the static output will shut off, switchback style, while the turn signal is running; if you are using the Turn Wire as a shutoff, just leave this wire disconnected
