Here's a pic of it in place. I still need to fabricate the 10 inches the mounts at the shift console. I will wait until I install the good trany after Dr. Evils Disco clinic. I should also mention that I have a sperical bronze bearing at the fire wall.

Today I tackled the wiring a little. I removed my engine tray, since I don't need it. It left my bulkhead wiring exposed and looking like crap. I decided on a bulkhead connector like a modern car. I'm sure Project Anklebiter will go with a similar system. Here is the before pic. Old factory 914 broken grommet...

Here is the after pic. Simple, weatherproof bulkhead connector. This alows me to remove the rear harness and get it out of the way during fabrication.

I had to cut the firewall and tunnel a little to make room for the connector and allow removal when needed...

Cut some pieces of fire cloth to keep the wires safe...

Welded up the bulkhead with 14ga plate. Might be overkill but the seat belt bolt is close by...

So the bulkhead connector was $25 online. I have the correct crimper tool ($149) already but there are cheap ones online too. After crimping, I soldered the crimp to make it last longer than the car...

Make sure you put on the little dildos before you crimp the connection...

I removed the large red wires from the harness. The ones that connect to the battery and alternator. My battery is in the front, so I pulled the red wires back to the fuse panel. I will route them to the battery up front. When I was done with the 914 wires, I had 8 empty positions. I filled them with spare wires. I will use them for something I'm sure... Notice in this picture, the starter wire was split, shrink tubed and crimped to 2 connectors. This is an acceptible method of making larger wires fit in smaller connectors. I will use a relay in the back to make sure I don't over heat the connection...

I plugged them together to amke sure all the wires match up...

So, here is the rear harness. I do need to make some repairs to the tail light portion and connect the engine wiring to my EFI and misc sensors...

Here it is plugged in at the firewall. It's going to look great once I get it dressed up...
That's it for now...

The crimps come with the bulkhead connector kit (eBay). The crimper I have had for 15 years, from when I needed it for work.

I love those weather pac connectors.

A great build, this will be an awesome car.

Are you going to be ready for summer?

If I find a job (got laid off 2 weeks ago) I can have it done by summer. At least be able to drive it and work the bugs out. Then I get to take it apart and paint it. We shall see... Running low on $$$. So I'm doing what I can without spending a lot.

Good luck on your job search.

At least you are putting your extra time to good use.

You have a lot of unique and inventive things on this car already.

The real wiring challenge has begun. So far I have repaired and modified the rear 914 harness. I have disected the RX7 (Cosmo) harness. I have the ECU harness with it's miryad of wires... (IMG:style_emoticons/default/blink.gif) I decided to use the Mazda engine fuse/relay panel and adaptit to my needs. It satrted by cutting it loose from the main harness and blueprinting the connections. So far I have the fuel pump and starter relays configured and the ECU power fuse. The fuse panel connections were "Hot all the time". I am using 2 Bosch relays as a master ignition control. The Bosch relays turn on the ATC fuses when the ignition is on. The Starter and fuel relays along with the Maxi fuses are Hot all the time and activated only when needed. The ECU will control the fuel pump and I have a power bypass in the cabin if needed. The starter relay is set up just like a hot start kit. I managed to get the engine sensors wired to the engine and routed into the rear trunk; Where all the magic happens. I have not decided on my final spark ignighter setup. The factory uses wasted spark on the Leading spark plugs and discrete spark on the trailing plugs. The ECU should be able to accomplish this but I am considering an MSD. I can use 4 MSD 6AL units and have 4 coils and discrete spark to each plug. This set up would allow finer tuning of the leading and trailing sparks. My budget is very limited now so the MSD will have to wait. I am taking donations. (IMG:style_emoticons/default/biggrin.gif)
Here are some early progress pictures. If you are scared of wires, don't look!

In this pic, I have all the wires in the trunk. buried are my note book and Mazda wiring diagram.

This is the engine with sensor connections in place. The wiring will get dressed up once I know they are correct...

It is taking a long time wiring because a solder and shrink tube everything. I also am designing this to be removeable when I need to prep for paint.

Here is a quick pic of the fuse/relay panel. I used my label machine as I connect to the system...

Well the ECU is 75% wired up. Still need the gauge wiring to the dash complete and some misc. I took a little break from the ECU and decided to fab up the alternator mount. Since I removed the A/C compressor, Power Steering Pump, Smog Pump and factory alternator it really cleaned up the front of the engine. The old alternator was a saddle mount and my 140 Amp Powermaster is not. So none of the factory stuff would work. I used some 1/4" steel I had laying around and made it to bolt to the existing studs on the engine. There was a massive cast aluminum bracked designe to hold the A/C and steering pump. I looked into modifiying it but it was a piece of shit. The Mazda alt pully was and easy swap from my GM V groove. Same I.D. and thread. I did realize that I don't have the curved tension bracket for my Alt so there will be some more work and a trip to the Junk Yard to pick one up.

So far I have 80 hours into rewiring this car. I under estimated the ammount of fab to go from a V8 to a Rotary. It looked so simple on paper... (IMG:style_emoticons/default/dry.gif)

Here's a couple of pics just for fun.

Mazda pully fit wo no mods...

Bracket painted and then I had to clearance the top left bracket a little...
