Can anyone confirm if I do have the correct ECU for a 2005 300X or is the ECU I have for a different motor?
Do they make more than one ECU for the 300 X?
Motorola
#'s I found on the ECU are:
885557
PCM 0308M
VK01P8X1

Thanks for your help in advance,
John

Hi,You need to scan it.The ECU will idenify itself as 300x.Any 555 box can be reprogramed.
