Intellitronix cluster setup to 4 cylinder (LS)

[Aruba1]

Guys, I am putting this on the main section instead of the LS forum in hope to get someone to chime in that is familiar with these cluster that may or may not have an LS.

The cluster comes from the factory setup for 8 cylinder but the instructions says that you can cut the blue wire to trigger the 4 cylinder mode which is needed for the tach to work with the LS engine. I found a diagram online for their tach "gauge" (same company) and on the gauge there are two wires that depending which one you cut will go on 6 cylinder or 4 cylinder mode. But on my cluster there are no wires on the front panel and I have nothing to cut. There is a blue wire in the back of the cluster that is for water temperature sending unit, lol, and I ain't cutting that.

Can anyone help? I hope to get this fixed without calling their tech support. I will post pics shortly.
