LMMF Party Mode Temp Sensor Override Switch — GM 2-Pin / 3-Pin Universal

LMMF Party Mode Temp Sensor Override Switch

Keep your GM derby, race, or off-road build running when heat would normally end the party.

The LMMF Party Mode Switch installs inline with your coolant-temperature sensor and lets you manually override temperature-based engine protection strategies when conditions get hot and rough. Start in Normal Mode for normal sensor operation; when your build takes a hit, loses cooling, or you need to stay in the fight, switch to Party Mode.

Universal for GM applications • Works with 2-pin or 3-pin temp sensors • Normally kept in stock • Usually ships within 1–2 business days

How It Works

• Normal Mode: Your temperature-sensor circuit operates normally.
• Party Mode: Lets you manually override temperature-based protection strategies for derby, race, and off-road situations.

What’s Included

• LMMF Party Mode control box
• Party Mode switch
• Wiring harness
• Reversible temperature-sensor adapter for 2-pin and 3-pin sensor setups

2-Pin or 3-Pin Sensor Compatibility

This switch works with either 2-pin or 3-pin GM coolant-temperature sensors. Simply reverse the included adapter to the opposite side of the harness to match the sensor style in your build.

GM Universal Fitment

The LMMF Party Mode Switch is universal for GM applications, including common 3.1, 3100, 3400, 3800, Ecotec, 2200 SFI, and LS-based builds with a compatible 2-pin or 3-pin temperature-sensor connection.

Other Applications

The Party Mode Switch can also work on non-GM applications. For non-GM builds, LMMF recommends purchasing a spare adapter so the correct adapter can be hardwired into the vehicle-specific temperature-sensor circuit.

Color & Availability

Select your preferred color before ordering. Party Mode switches are normally kept in stock and usually ship within 1–2 business days. Certain colors can sell out temporarily, but LMMF can build more quickly when needed. Check product availability or contact us if you need a specific color by a particular date.

Before You Order

• Confirm whether your coolant-temperature sensor uses a 2-pin or 3-pin connection.
• For non-GM applications, purchase a spare adapter for hardwiring into the vehicle-specific temperature-sensor circuit.
• Contact LMMF before ordering if you are unsure about sensor style, wiring, or compatibility.

Normal when you need it. Party Mode when you cannot afford to quit.

For off-road, race, engine-swap, and demolition derby use only. Not intended for emissions-controlled or street-driven vehicles.
