Buying an ECM on ebay, what VIN to give them?

[operatorfailure]

I need an 0411 ECM for my 5.3 swap and the company will put any vin in that I want, but I don't know what to give them. If I could use the vin off my 68 c10 it's going into, that would be cool but it doesn't really matter, since there is no emission testing where I am and they don't care what vin the computer shows. All I need is a vin that will work for sure with my setup (5.3/4l60e in a 68 c10). I already screwed up and bought an ecm without finding what it was out of and now I have a v6 astro van 0411 ecm that does me no good. So basically, what do I need to tell this guy?

Thanks in advance!

You need to figure out the VIN that the motor, trans and harness came from. Everything needs to match and be compatible.

Go to a junkyard and look around for a vehicle with a 5.3 in it and copy the VIN #.

There's thousands of 5.3 VIN's floating around the internet. Why make it difficult? The VIN is on the engine block!

Tell them to leave the original VIN untouched, this way you won't have any problems

who you getting it from? spareecm? if so just tell them you need it with a 5.3 and 4l60e. they will pick the one for you. Also you need to know if you want a truck or car file for a/c and 4 wheel settings. the 411 you have know can be used. you just need to get a file and do a write entire.
