2003 GMC Envoy, Prestige APS-996a

I just finished installing a Prestige APS-996a Security system for remote start capabilities only on my wifes 2003 GMC Envoy. I wanted this system for the 2 way remote and the extended range. I installed it along with a DEI 555L Passlock II bypass module. I just found this site halfway into the install and was finding alot of talk about the DEI 457G all in one bypass. Now the next step is to hook up the dook locks and possibly driver 1 & 2 memory to the remotes. Should I have purchased the 457G to do all of this and will it work the driver 1 & 2 memory or do I just wire into the door with relays for the memory feature also does anyone have the wire diagram for the 457G. Or do I just purchase the 555G and will this work the driver 1 & 2 memory or do I just wire into the door with relays for the memory feature also does anyone have the wire diagram for the 455G. Ok last question I read to hook the tach to the white wire connected to the instrument panel and thats what I did it works fine I tested the wire with my fluke before attaching it but I don't see anyone else hooking in there everyone goes to the PCM white wire is it the same wire?

Thanks in advance

Ok so the 455G is what i need does anyone have the wiring diagram for it? I would like to see it before i get it.

Thanks

Also does the switch on the dashboard that overrides the dome light affect the alarm since it is to be connected to the dome light? If the dome override is on and alarm set and door opened light would not turn on and trigger alarm? Or does the 455G correct that problem?

Thanks

Has anyone found a bypass module that controls the driver 1 and 2 memory seats on a 2003 Envoy? Bypasskit.com has a icon for memory seats on there modules but installation manual does not show how it would hook up. I have noticed a number of people having problems with the DEI 457g anyone have any advice on them?

This is what i have Prestige APS-996a with 555L passlock bypass. What I want to do is connect keyless entry function with driver memory with least amounts of modules and relays.

Thanks

Thanks.

That is awesome info.

I greatly appreciate it.

The envoys are nice in two respects; if the unit you are using has a tachless mode and you can get it to program to your envoy, the truck has a factory crank protection so it will always crank perfectly no matter what the starter wire output length is; other nice thing is there are door lock interfaces by omega and bypasskits that when you lock the doors with the aftermarket transmitter, it will automatically roll up all four door windows through the data wire, no extra relays or labor. i don't have the model numbers handy, so happy hunting if interested and i'll try to post them later.

That would be great if you have the model numbers they have so many bypasses out on the market.

Thanks
