Not all window switches will work with our cars. MSD makes two kinds of window switches: cars with distributors and cars that are distributorless. The product number for the distributorless window switch by MSD is 89561. If the circuit requires over 1.5 amps (like the zex) then you'll need a MSD high current relay. Get the Single-Pole Single-Throw 30 Amp/12VDC, product number PN 8961. Then you'll need RPM module kits that come in either even or odd increments sold as sets 1000 RPM at a time. For example. 3000-3800 (even only) is PN 8743. 8100-8900 (odd only) is product number 87481. 8000-8800 (even only) is 8748. You need to buy one set which includes your activation rpm and one set that contains the deactivation rpm you want. If there are other rpm ranges you want, let me know by pm and I'll get the part number for you.
