Default MSD Window Switch Modification ??

I recently received an MSD window switch and an MSD shift light. I have read on this forum that the window switch (and i assume the shift light) must both be modified to be able to work with the LS1 ignition system. To my knowledge MSD will charge $35 per item to "modify" them to work. I had also read that the modification is to simply set up the device to work as if it was installed on a 4 cylinder car, although some have complained that even after cutting the two loops the switch still would not work. If anyone can shed some light on the subject or perhaps direct me to some sort of modification instructions it would be much appreciated, i wouldn't mind saving the $70 + shipping costs if possible. Thank you very much in advance.

I never figured out what the modification was for. I bought mine a couple years ago and set it up without sending it in to be modified and it has always worked.

cut the 2 wires, and try it 99% of people have good luck.

if it does not work, send it in.

Thanks guys, i'll try it with the shift light first. If that doesn't work it won't be as big a deal as a malfuntioning window switch.

The ls1's are set up on the 4 cylinder mode. It will work fine. We've done a few.
