wiring

[blazin78]

i drive a 78 k-5 454bb i had a fuel line rupture, and caused a engine fire, i have fixed everything but i am having a problem with the electrical. it fried my ignition module, parts of the column, under the hood and most of my under the dash harness. i rewired most but still having a problem with a short. i checked over everything replaced the fuses; start the truck and about 2 min down the road i get a flash and i lose all the lights in the truck besides my head lights. any info please let me know /forums/images/graemlins/dunno.gif

If I've got this right the '89 alt is what you want to run in the '87, but the wiring is different, correct?

alt adapter I think is what you need. A few on this site have used that piece, hopefully they chime in and confirm. Im not 100% on that, but hopefully saves someone else from digging up the part number, and they can just say yes or no as to if it will work for you.
