791xv, 98 Expedition

I have several print outs for 98' Expedition. Trying to install 791xv alarm system. According to these print outs the door trigger wire is light blue/white, but when I put my meter on the wire there's no voltage. And I also was told that this wire would come from the anti-theft module where the wires for lock/unlock are located also. Any help is greatly appreciated.

Use the BLACK/ blue wire coming out of the drivers door harness. You can also get it in the harness traveling up next to the keyless entry mod. It's a positive door trigger....Mike M2

Thanks Mike I'll give a try and let you know if I got it or not. One more thing Mike, do you know what wires to cut for key side and starter side for the remote start?

Thanks again.

Does anyone know if there's an easier way to get to the techometer wire in a 1998 Expedition 4x4. I know it's pink/white, but the harness under the dash, I cannot get to it. Any help is greatly appreciated.    Thanks

If you are using a dei just go to the uncommon injector wire might work with other systems also just not for sure.
