Here's a few more pictures and a video of the shifter movement.

One of the pictures is the throttle cable. What I did was cut the 626 cable sheath and threw away the cable. I then took a 3/8" bolt and cut off the head and the threads so I had a solid rod. I bored one end 1/4" for the Mazda sheath and 5/16" into the other end for the sandrail's sheath leaving 1/4" between the two holes inside the middle of the bolt. I then drilled through it 1/8" to allow the cable to pass. Each cable goes into the ends of the bolt and taped up. I bought 1/16" cable from Home Depot to use as the new throttle cable. For the throttle body connection I used a 6mm bolt and drilled a 1/16" hole through it for the cable then set it with a punch. It looks like a typical throttle end and holds tight.
There's some pics of the wiring harness's flying ends. I tagged them all as to their functions and ran my harness in the frame rails up to the cluster where the power distribution and relays are. I know it looks like a mess right now but it's all getting tucked away into a box behind the passenger's seat where the ECU will be located.
The 4 relays are:
-Ignition power (high side signaled from ign switch)
-Injection/solonoid power (high side signaled from ign switch)
-Fuel pump power (low side switched by ECU)
-Starter interlock (high side signaled from ign switch, low side switched by neutral switch)
The 6 fuses are:
-Ignition 10a (to ign relay)
-Injection/solonoids 10a (to inj relay)
-Fuel pump/starter 10a (to fuel pump relay and starter relay)
-Turn/brake/horn/relay power 20a (turn/brake/horn off ign acc position(off while cranking). Relay power off ign terminal of ign switch)
-Head/parking/dash lights 20a
-ECU memory 3a
A 7th 20a inline fuse feeds the offroad lights.
An 8th 20a fuse will be located in the ECU box to provide power to the fan relays which will also be located in the ECU box.
The last pic is the bracket I made to use a Honda Civic's AC tensioner as my water pump belt tensioner. I removed the power steering pump so I needed to add an idler in it's place since that belt drove the water pump. It was easier to do it that way then to relocate the alternator. The alternator has it's own belt and tensioner. I still need to make a couple spacers for it.
