I hope this is the right place for this question as it kind of crosses with the engine forum.
The LS3 connect and cruise package is what I have settled on for power. My question is in regards to the wiring and placing as much as I can in the trunk vs. under the dash.
LS3 fuse block and Autowire Highway 22 harness fuse block: I would like to keep the electrical system as clean/simple as possible. The LS3 comes with it's own fuse box for the engine controls, but I will already have a 22 circuit fuse block with the Autowire kit. Can the LS3 fuse block be deleted by extending the wiring (same gauge) direct to the Autowire block, or would it be best to keep the two separate? If it is best to keep the out of the box configuration, can the LS3 fuse block and ECM wires be extended to the truck without issue?
FF harnesses: As I understand it, the kit comes 4 harnesses. Main, front, dash and rear. After contemplating not using the supplied FF harnesses I thought maybe it would be best to keep them solely for the connectors like the steering column. What are your thoughts considering I will be using the Autowire kit? If I do not need it, is there a deletion credit from FFR?
