Ok, after a lot of trial and error, I discovered that I was not supposed to cut the red wire. I just hooked up the blue and green wire from the PAC up to the red wire from the HU. The red wire from the PAC to the yellow of the HU and then the black wire from the PAC to ground. It worked then. Of course, I did this after programing. I also had to run a constant 12v from the battery to the yellow wire of the head unit. BTW, I have a 2003 Ford SVT Lightning(F150).

Ok, thanks. I'll go the PAC route then. Anyone got some more indepth "How-to" on the programing of that thing?

Thanks, that does help a lot. What I was more or less confused about was the directionality of the diode and capacitor with respect to +/- sides and the coil side of the relay. "+ (banded side) to a RS part number 272-1022 capacitor's + side" Banded side is the cathode and -. I guess I'm just not reading correctly or it was a typo on his part. <BR>As for the relay, I can just put a jump across both switch terminals, and another across both common terminals? Is the attached diagram correct?

Any new updates on the upgrade?

I'm gonna try this same thing, but am lost without pictures. Any help?

Were you able to pursue anything with the blood evidence?

Could you post a picture of this?

Yes, you need to drive around for a while so the system can calibrate everything.
