Max because I have an engine that don't match up
with the usually harness on the VG engine I been
to a couple of salvage yards but still can't find
the harness that i need, anyone able to help me out
as far as pinpointing the year differences?
I only need to order the back 2,4,&6 but don't know
what year the car was the engine came out of.

Thanks in Advance
