The Granatelli Dual Window Switch install information that came with the unit and the website have conflicting information. I called them and they where very helpful in providing the following information.
There are eight wires on the unit and it goes like this:
Note: not all the wires need to be connected ie, tach output, RPM input hi or lo and TPS. Depending upon setup and use.
1. Red= 12vdc input
2. Blk= Grnd
3. Purple= Sw1
4. Blu= Sw2
5. Grn= TPS input
6. Org= Tach output
7. Yel= RPM input 12v
8. Wht= RPM input low voltage
Hope this helps anyone installing the window switch.
