I HAVE A 97 GRAND PRIX 3.8sc ENGINE BOUGHT WITH NO WIRE HARNESS. i'M LOOKING AT A 99 WIRE HARNESS AND WONDERING IF THIS WILL FIT MY ENGINE. IF NOT DOES ANYONE ON THIS FORUM HAVE AN EXTRA I COULD BUY?

Is the '99 harness from a SC'd engine? If yes, then I would think it would be ok....

according to the ebay ad it is. expensive so I wanted to be sure before I bought.

well, to verify it.....go to ANY GM Parts Dept., have them look up the part number of each harness for each year...if the numbers are the same, definitely good to go......if different, there could be minor changes.....
