Hello I have a 2006 lq4 6.0 it has the 24 ring on the crank .
I'm putting it in my 1938 Oldsmobile coupe and I have a 04 Dbw throttle body from a Tahoe it has a 4l65e transmission and I need to get a computer and wire harness for this motor and I'm planing on running the truck intake for next summer then doing a heads ls3 and cam and intake ls3 change over the winter

What wire harness should I buy a truck one or one from a car ?

I'm getting one from the wrecking yard and I'm going to make it a stand alone harness .

I don't like the look of the truck harness over the intake so if I did use a truck I would have to modify the harness .

Thank you kelly
