LS Wiring harness

[ClassicHauler]

Hi everyone,

I have a 64 C10 that I bought a 5.3 and 4l60e combo for a few years ago.
since then I have been trying to find a wiring harness for it since that is the only thing my engine didn't come with. I know a lot of you have put these engines and transmissions in your trucks so I was just curious as to what harness did you use. I know there are a lot of them out there and they are all fairly pricey and I have also been considering a used stock harness and making the modifications to it myself. Any input is welcome, thanks in advance
