My Rx2 does not have 1 single wire remaining from Mazda. Every wire in it I ran myself. I don't really like the way I ran the wires though. Mainly because I suck at it. I don't really know when to use a terminal block, fuse block, fuses, etc. So it's really just a hodge podge of whatever I decided to run at the time. I also did this at various times and the shows.

I'm looking into some "wiring kits" but I don't really know what to choose. If anyone here has used one to wire they're car from scratch, let me know what you used.

Details on the car for reference, I only need the basic essentials:

Webers (non-fuel injection)
Tfidfis ignition with HEI Ignitors (Coil on plug)
Push button start
Mallory 140 Comp pump on a switch
Electric Water Pump on a switch
Electric Fan on a switch
Headlights on a switch (Would like to have A switch dedicated to driving lights only)
RPM, Oil Pressure, Engine temp gauges (fuel pressure as well, but it's mechanical)
No brakes lights ran yet. So if a kit included this as well, that would be awesome.

 

Have you looked into the painless wiring kits, I remember reading a couple threads where they used them to wire their cars. They have them for different amount of circuits

 

Painless will work fine but there way over priced. Check out Rebel Wire. They are made in the USA and high quality for a really great price. Great technical support and great to deal with. Its what i used in my Rx3 and i Have no complaints

 

I have no firsthand experience with the kits but I've good things about the Summit Racing kits. Cheaper than Painless but basically the same.

For the items you listed, buy a K&R or Digital Delay switch box. I run K&R and simplified my whole harness.

 

I use ez-wiring on most our oldschools and work great
