Working on refurbishing used wire harness, Refurbishing complete harness for 73 914-V8 project Options

[Daryl32]

So the refurbish for the 73 914 with Chevy 350 is now at the "What is this Mess?" Stage

Wiring in front bonnet area looks great - but once it goes through the "fire wall?" not sure what you call a front bulkhead? The wiring really takes a turn for the worse.

The owner got a new to the car complete harness with it. It is a used harness that was removed from another car pretty much intact. The only real issue with it, is that some of the wires were cut with a cut off wheel. The area is where it came through the rear bulkhead.

Plans are to use the 12 wire plug wires for the engine and gauges, some for what they are for.

Wondering what others have done? Any help will be gratefully accepted. (IMG:style_emoticons/default/cheer.gif)

I found wires in the car that went no where just attached and cut at both ends.

Some pictures of the wiring:









After new used harness was unwrapped and inspected, I rolled it up and set it on the floor of the passenger side of the car. Went into the house and had a medium old guy panic attack. (IMG:style_emoticons/default/confused24.gif)



A couple of weeks later I started to tackle the new harness - laid it out of the table and had at it.

I made a 4x8 table out of a sheet of plywood and covered it with cardboard, then laid the harness out for inspection. I started tracing wires to see where they went and inspecting for cuts or bare spots. I removed the factory fuse panel as the car has a bigger blade fuse style panel in it.

Dick the car was gutted of it's wiring 10 years or so ago - and the new old harness did not come with an engine bay relay panel. I may make one if needed, still working all this out.

Still trying to work out what relays at the engine a 350 really needs. None of my old Chevys ever had - have any.

Did you use any inline fuses for new things?

Fuel pump should be on a relay, factory 914 one is fine.

Fans should be on a relay

Thats it. You'll need to wire in the alternator, maybe a choke if you use one, and the power wires to the distributior and the distributor to the tach... Thats all you need with a v8.
