Time to start my swap thread. I hope you all can guide me through this process since I have already encountered some issues. I have been researching this swap since I had my 85 c10, so a total of about 6 years on and off. Y'all feel free to chime in with any info you think is helpful!
So here's the truck 89 K5
And now weeding through the factory wiring at the bulkhead connector. Anyone have a pinout? I ordered a 89 GM wiring manual, hopefully it will have my answers!
