Hey all,
First post here.
My question is I have a 3800 SC from a 1995 park avenue and a junkyard find wiring harness, ECM and fuse block from a 2002 GTP. Will they work together? I am using the engine for a long travel sand rail project my son and I started. So the harness will need to be pinned out for a stand alone system. Any advice is greatly appreciated!!
