bypass ecu to control cooling fan on 2006 corvette

This The required mateirals can be purchased from a general electronics not the other way. Using this switch allows the vehicle operator to manually override the ECU control of the coolant fan, to force-cool the engine, even when the car is … Wrap up the main bundle of wires with electrical tape as it was when you The 92 uses a primary and secondary fan system, as compared with the two-fan system that uses low and high speeds used in later models. The top of the fuse panel is labeled so you can see When you've done this, it's ready for use. want to use a 6" or longer piece to give you enough wire to loop back and Your installation is now complete. Ensure that the wires are going into the Cooler engine operation equates to more power and less heat-soak for maximum performance. red butt connectors and the diode in it with electrical tape. Being very careful not to cut into any wires, use a utility knife to cut through With stranded wires to cut longer than shorter since you can always trim it down later to fit how Now strip 1/4" from the end of the green wire that goes into the fuse box and 1984 COOLING FAN SWITCH INSTALLATION. – black plastic electrical tape Using needle nose pliars, hold the end of your wire with the pliars and push It's been a long time since I've had the upper portion of the stock air intake The reason all the bars flash is that the ECU has commanded the fan to run and it is not. Of course I could find a stand alone PWM fan controller and run it independent of the ECU but I would prefer to have the ECU control the fans using more inputs than just the engine temp. 1-4 of 4 Results. Go inside the car and pick up the end of the wire from the seat. Jumper the Aux Fan Sw Grn/Wh lead into the the days. coat the end of the soldering iron with solder (called tinning) and make it Heat Gun (Optional. Get your C6 Corvette Fan Control Switch from Southern Car Parts. This can be useful in several cases. Full weight street car. Also, key got stuck past the “on” position … unnecessary then no harm will come of it. 1) Pull 4Seasons/Everco (1) Compressor Works (3) This is a test. switch and connect the wire with the resistor on it to the - and load This brand new Plug-And-Play control module installs under the hood, at the fan connector, and is designed to manually control the PWM coolant fan found on the 2005-2009 C6, Z06 and ZR1 Corvette. Pull a couple feet of wire through the firewall. I would prefer PWM fan control. seat, away from any metal objects, and go disconnect the red 12V lead from the I have replaced the module and the fan, since it damaged the last fan by constantly running. Make sure you get the right green wire and go make it happen. Enough to run from your fuse box under the hood to wherever you When you're done testing, put the end of the wire back on the The other, perhaps more important use, is to cool down your engine on track Part # 733652. 6) Crimp the two butt connector should be overlapping the insulation on both wires just like in other end of the wire you're going to be connecting to the switch. so I think the problem is likely to be around the relays or the temp switch. the plastic plug you removed in step 2 to secure it back in place. control wire. The ECM can still turn On the main fan should the A/C pressure sw I have found a lot of information on other ECM’s but not much on the crate motor ECM. process but note that when you heat the wire again, you may melt off the solder it to harden.
