If you wire it right the newer pcm will run the abs. abs module just needs like one or two pieces of info can't remember right of hand but I can look at my notes tommorrow. And you can use the oil sender from the LS engine.
yeah all the brake control module needs is a VSS signal.
What computer will you be using? The 0411 computer, or? The '95 thru '98 OBDll truck wiring, were transition years. In other words, some of the wire colors/codes that came out of the drivers side firewall had different functions(but not all), for all four years. Nothing can be counted on from one years wiring to the other. I recommend you go on E-Bay & purchase the same year GM brand Service Manuels that apply to your truck. Don't buy aftermarket. They are invaluable to you now...and in the future. They have all the wiring schematics & are actually very easy to understand. Basically, every wire(except a couple) that comes out of a GM OBDll computer is a ground. When the computer gets a signal from a particular sender or sensor to turn something on, it gives that accessory a ground, usually via a relay. In your trucks owners manuel, there is also a fuse diagram, that can help you identify each fuse function/wire in your power center(fuse block), on your drivers inner fenderwell. I removed my trucks original 1996 computer, and cut all my wires off exiting the firewall, leaving plenty to connect my standalone F-Body(0411) harness wires to. 1996 trucks still used regular anolog gauge function, so everything is pretty straightforward. Identify the speedo, tach, oil-pressure, water temperature, fuel level, etc., wire color coming out off the dash, and butt connect onto them. I used uninsulated silver butts & epoxy heatshrink. As mentioned, all your ABS module needs is a VSS signal that your new computer can provide. There are(if memory serves), three different VSS signal pulse strength wires exiting the computer, so you just have to look up what the ABS module VSS signal strength of those three, that it needs, and connect up. All the wiring to the ABS does'nt need to be cut or disconnected in any way, just one of those VSS color signal wires. By the way...NEVER use a test light on a LS1 computer or wiring harness, to test a circuit fuction, as it can damage the computer. Use a digital meter only. Get the book & your home free. Hope this helps.

Yeah I'm using the 411 PCM out of a dbc truck. I think its a 2002 PCM. I know to go though my wiring and keep the normal stuff like, oil, water a/c wires. My wiring harness has a wire that turns my fuel pump on so I know I need to find it and hook that up. I just plan to cut the wire coming out of my PCM now and hooking it up to my new PCM. I guess I need to get a service Manuel for my truck.
You need your PCM in order for your ABS system to work.
so we need to figure out which vss wire to connect to the ads module for it to work, any idea with wire out the new pcm it is and which wire going to the abs we need to connect it to is?
