Re: What year motor?

Verifying the VIN of the vehicle that the engine came from is the easiest way.

8th vin digit U.....LQ4.
8th vin digit N.....LQ9.

Ive had wreaking yards try to pass off LQ4's as LQ9's.

I made a jumper/patch harness (PCM plugs with power, ground & data link connector) & use my Tech 2 to read the VIN thats in the PCM.
