. to sart off, im in the middle of swaping a 454ci on my 1970 c10 in place of the old and tired 307ci. the 454 is a 1994 tbi, but i swapped all the out because im gonna go carburated and bought a electric fuel pump since it does not have the hole for the mechanical pump nor the cam. now the issue comes when i wire the alternator. since i cant use the altenator of my original 307 since the 454 is a serpentine, i need to convert the wires coming out of the 454's alternator to properly charge. but for that i need a wiring diagrams. when i bought the engine it did not come with a alternator, so i dont know exactly how the 454's alternator harness is going to look, but ik they are different in some way at least.

TIA!!

Note if you don't have an idiot light you must use a resistor.
