Lock Problem in 2004 Grand Cherokee

I just got a new compustar remote start that also has keyless entry. The module supplies a single negative lock and single negative unlock pulse wire. It seems like my car has type c door locks but when I power probe the wires it looks like they are running on a 5v reference instead of 12v. How do I wire into these locks so I can have keyless entry??

It's also worth mentioning that I have the remote start part working 100% and said FU to a bypass module and just taped an extra key by the key cylinder. It works fine for my purposes. It's a compustar 2 way remote start with the lcd screen and it's also got an alarm with a shock sensor, siren, etc (also hooked up). All I wanna do now is hook up the parking lights (headlights are already hooked up). I read that the parking lights need a ground pulse through a 1300ohm resisor to activate? I don't want to get into the trouble of getting the 455JW because quite frankly it's not very well documented and I'm impatient waiting for shipping

Not using a data module to control the door locks in that vehicle is a labor intensive and time consuming task. Basically you will need 4 relays and have to go into both front doors to complete the install. If you want to go that way, here is a link to some helpful information from Bulldog Security :     http://diagrams.marktoonen.nl/DOWNLOADS/3430_GRAND-CHEROKEE_JEEP%20GRAND%20CHEROKEE%20LOCKS.pdf They show it with their prewired "778 relays" but you can duplicate it with regular 30/40 Amp SPDT relays. As for the Parking Lights, yes 1,300 ohm resistor. Here is a link to Bulldogs info :    http://diagrams.marktoonen.nl/DOWNLOADS/14301_GRAND-CHEROKEE_GRAND%20CHEROKEE%20PARKING%20LIGHT%20DIAGRAM.pdf They use a relay controlled by the (+) Parking Light output from the R/S system. Here is a link to a Pictorial on your Jeep that shows the Parking Light MUX wire.     https://www.the12volt.com/installbay/forum_posts.asp?tid=137527 Soldering is fun!

If I only put 1 relay in each front door, won't it only control the 2 front doors?

Also, I already have all the relaus. Once I get the door panel off, there are the 2 wires running from inside the boot up to the switch and those are the only wires I see. Where do I splice them?

You can actually get to the 3 connections of either of the door lock switches. You can then use only 2 relays in only one door. This will unlock and lock all 5 doors. It has been a while since we have done 1. If you remove the housing from the door and take some pictures I can guide you. This duplicates the switch being pressed. Relays as such. 30 of both relays to the common connection of the switch. 87 of 1 to the lock of switch. 87 of the other relay to unlock.    This does require soldering onto a circuit board. And following traces from switch to the next down line connection to solder to.

If I can avoid soldering, I want to do that at all costs. Even if it's following the instructions by kreg. After I destroyed my gauge cluster on my other vehicle while trying to changed light color, I'll never get a soldering iron close to a vehicle again lmao. So basically I need 4 relays, 2 for each front door...

Here..4 relays 2 for each door (even though it only says 2, but shows 4). Will this work if my RS/KLE module outputs a negative pulse for door locks? Is that what this diagram is for?
