Question about ECM

[sandcrab74]

I was wondering if there is a way to figure out what ECM I have in my 2000. When I bought it it was already chiped so I dont have the numbers off the stock one. So if anyone can help it would be great.

Thanks

Remove the pcm. There will be a tag with a 4 digit code. The chip only plugs into the pcm.

Im not sure if the SD's are the same, but I think they are. You can read the PCM code if you stick a mirror between the PCM and the fender, there is a sticker on the PCM and you will see a code on it, of course it will read backwards and possibly upside down in the mirror. You can also remove the E-brake assy and the code should be on a sticker on the back of the PCM as well.
