Frequently Asked Questions About Freightliner FLT Cabover Gauges & Switches
What years and models of Freightliner FLT cabovers are these gauges and switches compatible with?
Our gauges and switches are designed to fit Freightliner FLT cabover models from 1984 through 1992, including the FLT86, FLT106, and FLT120 series. However, compatibility can vary based on your specific truck's configuration and any modifications made over the years. We recommend checking your existing gauge dimensions and electrical connections before ordering, or contact our support team with your VIN for verification.
Are these gauges direct plug-and-play replacements, or will I need to modify my wiring?
Most of our FLT cabover gauges feature standard electrical connections that match OEM specifications, making them direct replacements in most cases. However, some aftermarket gauges may require minor wiring modifications or adapters. Each product listing includes specific installation requirements. For switches, verify your existing switch type (rocker, toggle, or push-button) and terminal configuration to ensure proper fit.
What's the difference between mechanical and electrical gauges, and which should I choose?
Mechanical gauges use direct physical connections (like oil pressure lines) and are typically more accurate and reliable, while electrical gauges use sending units and are easier to install. For FLT cabovers, we recommend mechanical gauges for critical readings like oil pressure and boost, while electrical gauges work well for temperature and voltage. Consider your installation skills and whether you're comfortable running pressure lines into the cab.
How difficult is it to install these gauges and switches myself?
Installation difficulty varies by component. Switch replacement is typically straightforward, requiring basic tools and 30-60 minutes per switch. Gauge installation is more complex, especially for mechanical gauges that require running lines through the firewall. Electrical gauge installation usually takes 1-2 hours per gauge, while mechanical gauges may require 2-3 hours. Always disconnect the battery before starting, and consider professional installation if you're not comfortable with electrical work or drilling through the firewall.
Do these gauges come with the necessary sending units and installation hardware?
It depends on the specific gauge. Full gauge kits typically include sending units, mounting hardware, and basic wiring, while replacement gauges often come as gauge-only units. Check each product description carefully for what's included. For mechanical gauges, you'll usually receive the gauge, mounting bracket, and tubing or capillary tube. Electrical gauges in kit form include the gauge, sending unit, and wiring harness. Additional items like gauge pods, bezels, or specialized fittings may need to be purchased separately.
