Our 51 GMC 100 was purchased with recent swap out of the stock 6 to a 350V8. The original wiring harness was severed, only power necessary to start engine is currently wired. I plan to keep it very basic, only gauges, turn signals, headlights etc need rewiring. Current wiring was cut at each lighting assembly. I did find the fuel sending unit wiring behind the seat.

I am considering purchasing a 12 circuit Speedway Motors wiring harness. I am keeping a tight budget as I plan on changing out the front axle for a complete IFS.

What is the most user friendly, economical way to go?

Thanks!
