Good news, the seats and modified cubby box are installed, tested and fully operational Here, installation notes and pics following on from previous posts...
note#1: I had already re-wired and replaced proprietary Mazda connectors with new std plugs
note#2: all wiring routed from/to battery box at outer edge to endure no cables catching on underside of seat
I planned not to fit the battery box cover plate, this to enable easy access to battery -Ve when seat is slid forward
note#1: electrical tape over top of rails to stop paint scratching during install - you will need to refit the rails a good number of times during install
note#2: seat heater connector seen top left - this is now cable tied to the inner rail
Seat heater connector close up sitting below seat lowest position
Here pic of passenger seat in forward position, carpet rolled forward and clear access to battery -Ve
Seats and cubby box install complete
Some additional notes:
- Made 3mm alloy plate bolted to inside rear of cubby box for fuse box and 30A relays - this to provide easy access should anything fail
- Installed 2x Carling switches to front of cubby box with seat heater rockers
- Ran 4x 30A cables directly from battery +Ve to fuse box i/p [DS seat heater, DS motor supplies, PS seat heater]
- Ran all 6x ground cables directly to battery -Ve [this to ensure clean/constant earth :. no faffing about with future earthing issues]
- All cables ran in spiral wrap for protection using 30A [yellow] spade connectors for fuse box & relays, and 30A 8mm ring connectors to battery terminals
- At install you need to make sure that the wiring is 1. firmly fixed, and 2. kept low level to ensure no fouling on underside of seat. This is achieved by using the rear of seat box plinth with st/st rubber sleeved P clips fitted to the seat box screws - here I've fitted all new fasteners as wanted to re-seal the joint between seat box and plinth

Some additional notes:
- Do not underestimate the time it takes to wire in safely/correctly. Done properly, wiring takes time so do not be tempted to rush
- Do insulate every terminal & do use either spiral wrap and sleeve to protect all wires
- Do use fuses on all supply wires [inline or fuse box], including a 7.5A fuse on the input to the seat heater switches [supply from IGN.SW cct]
- Do use 30A relays on the seat heaters - do not be tempted to run these with just a fuse, it will fail at some stage and a seat/wiring fire is not ideal whilst driving
- Do wire in the seat heaters from the IGN.Sw [White, WhiteOrange, WhiteYellow] cct
- Do not wire from permanent live [Brown] cct as a seat heater accidentally left 'ON' overnight will at best drain your battery flat. At worst things might get a little smokey
- For best practice I have copied the Mazda RX8 seat wiring spec's + improved the wiring load rating
