Been quite some time since I've been on blew my 3.0 headgasket back in February and thought I was going to do a 3.4 swap but due to the point in my life time and money. im biting the bullet before winter to have my 93 running. Someone has a 3.0 bored .30 rebuilt top end timing belt and water pump replaced. Recently new clutch wanting 1,000 for it. Engine only has 40k on it. The engine is put of a 90 pickup. Is there any difference between connections for engine to harness. I know there some possible changes year from year. Correct me if I'm wrong
