Battery Isolator Selection And Install Gmt900

[miande]

I want to install a deep discharge battery for auxillary power and consequently, need to install an isolator. The only directions I have located make reference to the Delcotron/Delphi CS or CS130-D alternators. These both have a 4 slot connector but my alternator only has a two slot connector. So, I am thinking I do not have the CS or CS130-D alternator. Some of the illustrations show the installation of a Sense Wire and and excitation wire. Can anyone tell me if these wires are necessary when installing a isolator on the GMT900. It is the 5.3 engine and would have the stock alternator. It looks like there are two different isolator models. One is 3 pole and the other is 4 pole. The 4 pole is needed if the excitation wire is required.

 

Below is a link to the installation instructions and wiring diagrams I was able to locate. I am thinking that the Group 1 install (first diagram page 2) is the correct one for my truck. Anyone know for sure?

Check out the Toyota installation on those instructions. It seems to be a 2 pole alternator. Should be what you need I would think.
