I don't want to incur the wrath of anyone for lack of searching out this topic, but I wasn't able to find what I need.

I recently bought a Python 4106p remote start system, as well as the Xpresskit PLJX for the Passlock system.

I have searched all over, and all that I can find is pieces of information scattered all over, some of which I don't know is correct (not from this site though).

What I am wondering, is before I tackle this, is there anything special that I need to know regarding the wiring? I have all of the necessary diagrams from this site for color codes and wiring, but one of the most trivial things I have found is regarding the door locks. Some places say a relay is needed, some don't. I looked at the diagrams, and they show a positive (+) connection, but some threads have stated that the Suburbans are a Negative (-) connection and therefore need a relay.

Would this be correct, or will I not know until I get into the wiring?

Thank you!

The Suburban for that year is POS (+) thus you will need relays or a DEI 451 module.

The default from your RS is NEG (-) switching thus relays required.

I only need one of the DEI 451 modules, correct?

Yes, only one needed. Plugs straight into the lock socket on DEI products, pre-wired and about half the size of a pair of relays.
