Default Question on engine harness. 71 coupe

My lower engine wires, that are original, are looking a bit crispy. Found the nice kit Wilcox has. Question is do I have to dig into, any under dash stuff or is it all just under the hood. Where does it start, does it just plug to a block and thats it and then route everything. Just debating the amount of work.
In the middle of all new exhaust, balancer, cooling, tires, etc. Have been enjoying it and driving it too much. Had not crawled under it enough and now I playing catch up. Thanks, J

the ign harness and the headlight harness clip together and then bolt into the back of the fuse block on the engine firewall side.

it's all down low under the brake booster and steering joint where it exits the firewall.

mine was covered in the bituminous tar like sealant, had to scrap away until i found the bolt.

It starts at the junction block shown below.. or what is called the bulkhead connector.

Remove the bolt from the firewall shown below, the pull the two harness's from the firewall. Then pry the two part for replacement. Once you have the two separated, its pretty much plug and play.

BUY the harness from Wilcox....its Lectric Limited, they have better pricing on them than you could get by buying into Lectric Limited for a $5K dealer order. Thanks Wilcox!
