This module provides the necessary signals to turn on C-Class electric fans from Mercedes. Simply tying the Trigger line to a constant +12v will damage the controller box for the fan in short order. These electric fans move an incredible amount of air; enough to cool the biggest of engines! The controller commands the fan to run only at the speed necessary, reducing noise and power usage.
The controller has the ability to use one of two temperature sensors, or it may piggyback on a 0-5v EFI temperature sensor.
Price is $150. Includes a harness and dash status LED.
The controller works with two different temperature sensors:
3/8" NPT: GM sensor TX3 or TX3T. Available from Rockauto or local autoparts places. Pigtail is Pico # 5615PT.
1/8" NPT: Autometer # 2258. Available from Summit Racing or local autoparts places.
Please select the option with the shipping method you desire. These shipping prices are for one controller. Please contact me for a more accurate quote for multiple controllers.
Please read this update:
All controllers will now ship out with the DIY harness, unless you email and ask for a complete harness, or a pigtail. Sorry, I just don't have time assemble them. The alternative is discontinuing the controller :-(
Please allow one to three weeks for shipment, if I need to build a harness. The DIY harness kits I can usually get out in a few days. Sorry, this is a couple side-gigs deep now, so they will go out, but I need to work them into my schedule. Thanks for understanding.
Current stock: 0 - more on order
Backorder available. Please allow 4-6 weeks for more to be manufactured. I will update the site/email you if this is the case.
New option: Build your own harness, to your own desired length! I supply the 10 pin plug and pins, and any weatherpack connectors you need. Serious builders only. Good wire crimper absolutely necessary!
