I bought a 6.0L motor and harness today for really cheap. how do I know if it is a Lq4 or LQ9? I heard something about the letter N being LQ9 and U being LQ4 in the vin??? is that right? where on the motor or computer would the VIN be? is it a normal 16 digit number? Thanks for any help!

I doubt that the motor has a VIN, but if you happen to have the VIN on the PCM, if the 8th digit is an N, then its an LQ9. If its a U, then its a LQ4.

sweet it has a N in that spot on the PCM!!! So what did this motor come out of? The heads are #317, someone else said told me tonight that the 317 heads were LQ4 heads? Any idea about that?
Thanks again!

Whats the first 10 digits of the VIN, I'll tell you.

317 heads came on my SS's LQ9. The 317s come on both motors.

if I have the right number the first 10 letters are:

86yctj9223

Is that right?

Thats 14 digits, with the N in the 13th spot - Not a VIN.

I guess I can't count because it has a N in the 13th spot on that number?

the full number is 86yctj922337n4ro maybe that is not the vin?

any idea how I can figure out what this thing is if there is no VIN on it anywhere?

Plug the PCM in to your truck, and use a OBD2 code reader to get the VIN. Autotap, EFI Live, Predator, etc...
