How do you wire a delay wiper motor on 1983 El Camino?

Wiring a delay wiper motor on a 1983 El Camino isn't a simple plug-and-play affair. The original system likely didn't have a delay feature, so you'll need to add a delay module or use a replacement wiper motor with built-in delay. There's no single wiring diagram because the approach depends on your chosen solution.

Here's a breakdown of the possibilities and considerations:

1. Using a Replacement Wiper Motor with Built-in Delay:

* Easiest Option: If you find a replacement wiper motor specifically designed for your El Camino's year and model *and* includes a delay function, this is the simplest method. The wiring harness should be largely compatible, though you might need to adapt some connectors. The motor's instructions will guide you through the wiring.

* Finding the Right Motor: This is the most challenging part. You'll need to find a motor with the correct physical dimensions and mounting points, and one that's compatible with your car's electrical system (voltage, amperage). Classic car parts suppliers or online retailers specializing in GM parts are your best bet.

2. Adding an Aftermarket Delay Module:

* More Complex: This involves installing a separate delay module between your existing wiper switch and the wiper motor. This requires understanding the wiring of your existing system and carefully connecting the module according to its instructions.

* Wiring Diagram Required: You'll *absolutely* need a wiring diagram for your 1983 El Camino's wiper system. A factory service manual is the best source. Without it, you risk short circuits or damaging your electrical system. Online resources might offer diagrams, but accuracy isn't guaranteed.

* Module Selection: Choose a module compatible with your car's voltage and the type of wiper motor you have. Some modules are designed for specific motor types.

* Professional Installation: If you're not comfortable with automotive electrical work, this is best left to a professional. Incorrect wiring can lead to electrical problems or even a fire.

Steps (if using an aftermarket delay module - this is a general outline, specific connections vary depending on your chosen module and your car's wiring):

1. Obtain Wiring Diagram: Find a wiring diagram for your El Camino's wiper system.

2. Disconnect Battery: Disconnect the negative (-) terminal of your car battery before starting any wiring work.

3. Identify Wires: Locate the wires going to your wiper motor (usually power, ground, and a signal wire from the switch).

4. Install the Delay Module: Mount the module in a safe, dry location.

5. Wire the Module: Carefully connect the wires from your wiper switch and motor to the appropriate terminals on the delay module. Follow the module's instructions precisely.

6. Reconnect Battery: Reconnect the battery negative terminal.

7. Test: Test the wipers to ensure the delay function works correctly.

In short: The simplest solution is to find a replacement wiper motor with a built-in delay function. Adding a separate delay module requires electrical expertise and a wiring diagram. Without the diagram and experience, you risk damaging your car's electrical system. If you're unsure, consult a professional mechanic specializing in classic cars.
