So I made a little more progress with the wire tuck. I got to the point of installing my firewall plate and the HDP-20 connector hole ready for final install.
I would suggest getting a second harness if you can. You will feel more productive if you don't have to tear your car apart to do the harness.. Plus IMO I think you can plan better with comparison layouts.I've always loved cleaned up engine bays/wire tucks. Might make this part of my winter project on my NA. It looks great!
Its been a while since I talked about my wire tuck and what I did. I kinda gave up going back and fixing the text walls I first made.
My new/redone tuck is quite nice, minimal extending of wires and routing of everything puts the freedom of how you want to handle things in your hands. If I over extended wires I left them like that instead of cutting even more, I wanted wiggle room.
My Fender grommets are from AutoZone, They are for Oil filler Grommets Like 5$ for two.
Firewall I used a DEUTSCH HDP-20 - 29 Pins 12-16-20 AWG
**EDIT** I will have to double check a few, I threw away the paper after I was done. Going off memory. I will take more accurate pictures here soon. =)
Ill take a picture with everything in testing place tomorrow <3
IRTB 1.6 92' Miata Running MS2 vMS3.0 Board (Launch Control Mod/Flat Shift)
I eliminated tons of wiring due to stand alone ECU and my car has no options. <3
I also shortened my hood cord to about 1.5 ft and made it a pull release near my bumper/fender.
