Hello Everyone,

Okay, what I'm now running into is the PCM brand. I'm being told that the '04 Bonneville may be a Dephi where mine (in the '01 Aurora) is a Seimens marked as follows:

The Housing is stamped: J1 Blue

This is all of the info as it appears on the label:

Seimens SIMTEC 5. G


SERV. No. 12562481


HDW NO. 12553671

HDW NO. 12553671



It'* from the 2004 Pontiac 4.6 engine, Donor VIN (1G2HZ54Y144252221).

So, does anyone know which PCM would have been in the "04 Bonneville... Seimens or Delphi?
