I have a 79 silverado that i swaped an 04 4.8l into it and i'm having some electrical issues. I used the factory wiring harness from the 04 and modified it per the lt1swap.com website and i just spliced the factory alternator wire to the 4.8 factory alternator. Now my problem is the fusable link wire that goes to the junction on the firewall. Originally i think the wire was a fusible link but somewhere along the lines an inline fuse was put on it and now I keep poping the fuse. It seems to happen mainly when its raining or snowing. Any advice or help would be greatly appreciated.
thanks

Josh
