73-76 Bulkhead Wiring For LS Swap C10

[Skid99]

Hey guys I have the 5.3 motor down in my 73 and Im about to begin the process of wiring everything up. I have a stand alone harness and ECM thats been reflashed for it. I need help with the bulkhead wiring and cluster wiring. I know based on Lonnies videos on youtube that I can repin and remove un needed wires. I would follow his video but his truck is newer 84/5/6ish and his bulkhead is different. I am also swapping in the 90/91 Burb/k5 cluster with electronic speedometer module. My goal is to have all the gauges work like stock. I know its possible but I need a lot of help. If someone would be willing to help I'd even be down to pay you via paypal. Im no good at reading wiring diagrams or schematics. Looking for someone to say do this: stupid. Thanks

Are you trying to wire all the wires going into the cab through the factory bulkhead? If so I think you may run out of open spots in the bulkhead. A '73 is really close to a '72 and there aren't that many spots to use. The truck in that video is newer with a bigger bulkhead. If you're just trying to do the gauges you may be able to do it though. What year is the engine? Who's stand alone harness?

Its a 2004 L59 Flex Fuel 5.3 out of a Tahoe DBW
I have a friend in/around North West Arkansas that does the harness work.
