No Show Wire Harness?
 

Does anyone know if there is a "No Show" wire harness kit for under the hood? I drive an 86 rx7 gxl n/a 5speed

Tucked harness? Shaved bay look? Doubt theres a kit...

Yep, no kits. It's a do it yourself, time to get yourself some wire wrap and ingenuity!

Looks like I got some homework to do.

Yes, you do.

As you study schematics and think "Oh looky at all the crap I can delete"...stop.
There probably is a lot of stuff that ultimately can be removed but there might be stuff you want to add as well, like gauge leads, fog lights...whatever.
Wiring you won't use can often be repurposed to control something else and has the advantage of already being in the loom and firewall grommet.
Just something to consider.
