Update time
Awaiting the crank pulley spacer coming back and a strut brace making up, but not being short of a few jobs, we have still been able to crack on and get some more work done, so there has been plenty going on. made a shelf/tray which bolts to the conveniently large seams at the front of the engine bay out of some 1.5mm sheet with rectangular box section tacked under it to give it some support. This is going to hold the battery, coil etc, and give us a place to neatly clip down the wiring loom.
With a route for cables now established it was time to start putting in some of the wiring. i began with the starter and fusebox cables going straight across the edge of the shelf close to front of the engine, then did engine and chassis grounds. the starter was an easy win, just needing the original wire from the starter relay cutting down and the appropriate ring connector crimping on. Once the larger cables had been run across the front to the battery i could get some split cable sleeving on it to start feeding the stuff in that i need to keep from the mazda loom.
Armed with the Mazda wiring diagram, a stanley knife and enough caffeine to kill a small child, i set to it, and ended up with this
The plan was simply to de-wire all the terminals i dont need from the ecu plugs, keeping the few i need. This was a pretty tedious job made much worse by the jap bastards using some form of horrid rubbery silicone shit to seal the gland into the ecu box.
