Outer Limits 4x4 Board

Thinking of getting the project HJ47 ute re-wired as it's a bit of a mess under the bonnet from previous owners and some things aren't working properly - and beyond my ability!

Question is how many hours labour would it take to change over and connect a replacement loom ? I know of a decent loom available, my car doesn't have many add-ons either (spots, aftermarket AC, CD player) - that's about it.

Anybody help?
Cheers,
Griff

unless the wiring is pretty bad or stuffed i would tidy up the wiring in it. hard to say how long not knowing how bad it is but could be between 1hr to 3hr
