I just bought a 2006 tracker party deck 21 from a friend.
I got it for a song knowing it had a minimum of cracked exhaust manifolds.
I have swapped a few I/o engines over the years but just did a direct swap.
I found a deal on a 4.3 MPI on eBay from a fiberglass damaged hull that is 100% complete.
Would I need to swap the wiring harnes from the cluster to the engine or is it the same round 12 pin plug as a TKS harness or do I need to find a harness as well?

I almost thought for a minute I lucked up and it was just the one core plug pushed out and the exhaust manifolds cracked but that was a no go. Oil level steady rising and when I drained it was like a vanilla milkshake.
