Has anyone or can you put a late model harness in a early model pcm? Blur and Green harness in a Blue and Red PCM? Please help Thanks

 

You can.. but you need the right color ends for everything to line up..
plus repin the harness

The colors are there so you cant put the wrong one in the wrong PCM.

Eficonnection has the colored ends you need.

and i can find a PCM Pinout if you need it.

 

Your goin to have to find the right OS to run the DBW TB, depending on the setup your trying to run..

Any more info on it?

 

1999-2002 Silverado

 

2005

 

Thanks for the info, Yea I am going to run a 2000 fbody PCM with the Blue and Green harness, and you are saying that I need a red cover to replace the green one Right? and the harness I have now is a drive by cable. But but what do you mean by the OS?

 

Yea,, the green cover wont let it go in a Red PCM and vice versa.

SO, your wanting to use a 03-07 harness (with DBC) with a 2000 PCM?

You get that harness off a Van?

 

yea the harness is out of a express van but I am repinning the harness for a 02 fbody, where can I get the red cover from?

Jonathan, Are you 100% sure that the PCM wiring is the same on the 99-2002 Silverado???

I only ask because I have heard the the 0411 PCM used in the 2001-2002 Silverado's have the charging system set up differently. I don't know the specifics but I believe they changed the pin for the charging circuit. I have heard of guys swaping to this PCM and having to swap a few wires for the chargeing system at the PCM or you get a check engine light for the charging system.
