{QUOTE=firebladeJJ;5521639]@Alanis001 how did you handle your Park/Neutral Safety box? Mine does not fit to the side of the 6l80. Run new wires or tap?[/QUOTE]

I actually took it off the 4l60 n left it plugged in and it just sits on top of the 6l80. I programmed the pcm to manual. I have not tried to unplug it and see if it will start with out it.

I dont know if that helps any or what to do with that information but there it is.

I actually got my speedo to work now but the pcm does not see speed so got to mess with that.

so just spliced in the speed output wire on pin 41 of the 2650 module into the cluster speed wire and for me adjusted in the software ppm to 1000 and got the right speed showing. Only thing the abs n park brake light still on so going to try and splice that into the pcm speed to feed to the abs module.

Once i get to the point where i can communicate with my 2650, I'll take a look at it too. I dont have the switch yet but its planned.

I'm going to my shop tonight to work on the truck, I havent been able to comm with my 2650, I think its my laptop, its too old or something, I've got power thru the harness but it wont find it.
