How much time required to replace wiring harness?

[TheJDMan]

Is installation easier with the engine in or out (SBC) and should I install the dyna mat before or after wiring?

Depends on if you are the type that puts pants on before his underwear.

I think it HIGHLY depends on skill level and experience.

A classic update kit with all the factory connectors on it will be a HELL of alot faster to do then
a Customized AAW Highway 22 kit that you have to crimp, solder, shrink every connector on.

I used updated Weatherpack connectors, custom gauge bezel, LS1/4L60e wired in.
So mine took me lots of weekends .......plus I was a newb. But I prefer the Highway 22 kit myself.

Doing my 442 next.

lmfao.....

I POR-15'd my car and put my sound deadener down before running my new AAW harness.
If you do it vice versa and stick that tar paper over the wires......it complicates your life later
if you have to pull a circuit.
