I am replacing the engine and trans on my 78 buick. The engine is completely out. There is a big relay switch or what ever it is called next to the power booster. There are three bundles of wires comming fromit. one set goes to the head lights and another( the big one) went to the carb, and other engine electrical parts. I want to replace the whole set of wires. Is that possible? If so what is the harness called, or do i need to replace each individual wire for each component? Is this cheap to do?
The answer lies in your question. It's called a wiring harness. You can get a complete wiring harness with the plugs and everything. Not more than $300. I haven't researched where to get one but try summit racing to start with.
