On these trucks my solution was to cut the ignition wire on the keyless entry module. Back behind the fuse box way up at the top of the firewall is the module with 3 plugs. I don't remember the color but it might have been pink. It is easy to find with a DVM. Cut this wire and the keyless will always work with no side effects...

Okay so can I leave this wire powered by the unit? Plus cut it closer to the rap with the rs or am I looking at blowing something? Do I just use the relay as stated before?

Or just cut it and tape it up?

Simply cut and tape. You can unplug the 3 plugs and pull them way down to test, makes it much easier...

I know just cut and tape, but is there anyway this wire always sees a 12volt charge and when switched in acc. or run switches to negative? Just want to cover every base.

No, it's a 12volts ignition wire. It will probably rest at a negative, but go to 12volts when the key is turned on.

Okay will go out and test the harnesses. I'll get back with results and wire color. Thanks

Okay I got it wrong there is only two harnesses coming out of the RAP module. I was curious so I unplugged the harness on the right first  with the vehicle running then tried the remote. It didn't work. So I plugged it back in. Then unplugged the one on the left and tried the remote. The remote worked. So I tested the wires by back probing them. The wire I found was a black wire with pink stripe. There is two of them so I dont recomend people that are trying this to just cut a BLACK/ pink you need to check which one of them is 12v run and acc. in the left harness that is plugged into module. I cut this wire taped it up leaving enough to reconnect it later if need be. Started the truck and tried the factory fob it works. Tried with the rs and works doors lock and unlock. The only thing I found is that when starting with the rs the mileage on the dash seems to take longer to pop on. Second is that the AC compressor doesnt turn on during rs. I dont really know if the compressor thing is something that happend due to cutting this wire or if  it was this way before. Because I never tested it, its cold out where I live, and have been using only the heater. The true test is long term if everything is going to continue to work properly. Have not taken the vehicle for a ride yet. The only con so far is the Ac thing. I figure I will look at that later. Like when it gets hot out 6 months from now or when i get really bored. I figure if this caused the ac not to kick on. There has to be an out put that will turn it on? Is there a place I can get a full wiring diagram online for my vehicle? I figure if I find this wire I could use the out put on the rs through a relay,and diode. So it turns on when rs is in use. Would this work or is my problem else were?

I haven't read your entire post, but seems you don't have an ignition or accesory wire powered during remote start!

I was sort of thinking the same, but I used the T-harness so I would not have to splice these wires. I will have to check tomorrow if they are connected in the harness right and if so probe the wires for power when the remote is on. I guess I shouldn't just assume that the harness from the company is wired correctly.
