PART I
Promised update on wiring
Battery Relocation - from engine bay to trunk- how to do it right
First step is to disconnect battery mounts and pull it away.
Then you want to locate wires you want , in this case there is one cable on minus paired with ground one and two cabbles on plus.
For the CX-7
At this state you need to equip:
- min 6x Cable sleeve for 25mm² cabble
- 2x cabble sleeve for 50mm²
- Heat Shrink tubing, for whole project at least 2 meters
- insulation tape (black and red one for marking + and - and also equip the material one insulation tape which prevent cabble from abrasions
- nylon cabble braid 12mm at least 30meters
- main power kill switch - rally one from sparco
- ANL fuse 300A and casing
-3 pieces of 4m 25mm² cabble each
firs step is only difficult if you are not sure you want this mod, there is no way back after this step:
1. Cut cables from battery terminals
2.Prepare wires for connecting in sleeves
3.Take out at least 10mm of isolation from cabbles.
4.slide sleeves and crimp them with SPECIAL SLEEVE CRIMPING TOOL (fex Yato YT-22857)
5.Crimp prepared cabbles from the other side of the sleeve and crimp them.
6.On the connecting point put heat shrink tubing. Connection is approximately 5cm so you want at least 20cm of shrink tubing. Put 2 layers
7. then you want to wrap the whole cabble in material insulation tape .
8.Apply nylon cabble braid at the whole length and heat shrink the endings using heat shrink tubing for estehetics.
Next part.
1.Drill 15,5mm holes as shown on photos and smoothen them using dremel and fine sand paper.
2. Apply Zinc spray to prevent rusting
3. Apply Epoxide base coat
4. Apply Paint (matching your chassis, for me Mazda 35N - sparkling black)
5. Install rubber cabble gland (for ex. YT-06878) AFTER PAINT HARDENS FULLY!!
6.Pull the cabbles inside
7. Make space removing some of the interior pieces
At this point you can put in order every cabble for estehetics.
Optionally you can use exhaust wrap band for cabble protection in engine bay as i did . I'm planning additional turbo install so it is necessary protection.
That is everything i done in 3 days .
Next part (PART II) will include installation of main power kill switch, fuse and connecting battery terminals and placing battery itself in trunk.
Battery relocation gives you possibility of easy adding tuning stuff without worrying of how to lay additional wiring, weigh distribution and much more.
Unfortunately uploaded photos are not in wanted order but may be helpful for anyone trying to attempt same mod.
THIS MOD REQUIRES SPECIAL TOOLS AND EVEN CUSTOM CNC'ED DRILL EXTENSION TO BE ABLE TO DRILL THESE UNACCESSIBLE HOLES.
As always photos, stay tuned for part II.
