just installed BRAND NEW PDC in my 2002 ram 4.7L. Damn thing cost me $500 and im still having electrical issues, all fuses/relays are brand new as well. problems are:
radio has no constant (resets every time truck is turned off)
antenna doesnt work (appears fine)
when key is off, nothing works (power locks, horn, lights, etc) almost like ignition is a kill switch.
Cruise doesnt work
a/c doesnt work
O2 sensors arent reading (horrible gas mileage, 6mpg at best)
runs VERY rich.

are all of these things tied to the same circuit? im soo lost on this

Have you had any ignition problems lately?
I'm not sure if it's all the same circuit.
Have you looked in the 3rd Gen DIY section for a service manual?

And just so I know...What is a PDC?

i havent looked for a service manual, no too familiar with forums as far as searching for those things. i dont have any ignition problems at all. i still drive the truck but the way its running is killing my wallet but i dont want to sell it. i almost think i have a unique problem here...

You need the manual to sort out the different circuits. I'm assuming you are talking IPM (Integrated Power Module) The O2s are powered from the ASD relay which also powers the fuel pump, injectors and coils. Since the engine runs, this tells me there is power, but you need to trace wires to see if everything is connected right. What codes are you throwing?
