Here is how to wire Electric Water pump to Vipec

[1qwkmini]

I know this is an old thread...

I'm wiring in my Vipec and Water pump!!!

For the Wideband...I can use either one of the aux inputs on the harness or the original O2 sensor plug (pre cat)...correct?
...If I use the O2 plug...I use the original signal and ground wires ?? which pins???--do I use this ground or do i need to run a separate ground to the ECU ground point (some discussion of this here...maybe it's just if you are using the Aux route)???

Water pump...Using the rest of the wires from the same O2 plug...I use the ground from pin 3 to relay pin 85. Pin 86 gets power from?? switched or unswitched(assume unswitched to allow the pump to run (as Jan described) after the ignition is turned off??

Last question---on the supercharger---do i need to weld a cap on the cover over the pump drive or is there an internal seal that will keep the supercharger oil where it belongs??

Thanks
