Dash harness

[barbersride]

? I have a 84 grand national, but I have a 87 motor conversion , would the 84 dash harness will it plug in the 87 engine harness?

it will plug in at the dashboard by ecm and at the fuseblock but the fuse block pin out on the 84 side isnt a match to the intercooled harness
you wont have switched power to the electric fan relays , you'd have to add that
i forget if the switched FP /inj feed or the cci feed is in same location
and you wont have switched power to the powermaster which is not usually an issue since most converting have vac or hydroboost

you can find an 87 fuseblock diagram at gnttype.org
