ECU

Resources

V8 Creative - ECU

Tips

My LT4 ECU didn't have mounting holes. Fortunately ICT makes a really nice billet mounting tray.
I installed a set of distribution blocks in the luggage container. It's super convenient and clean with the ECU, amps, and rearview mirror/camera all needing connections.

Front Bulkhead Power

Tips

A friend recommended I install a breaker as an extra safety. In the case of a malfunction (e.g. starter locks and tries to draw too much power), this prevent a dangerous about of power. I got this one on Amazon for $27. Also, it's super easy to turn power on/off when you need to work with the wiring.
I needed power for 4 wires: starter, wiring loom, engine harness and stereo (distribution block). I added a 2 post terminal to handle this. The battery connects to the breaker and that connects to the 2 post terminal. Notice the left post has the starter cable so the power doesn't need to flow through the terminal.

eBay - Brake Bypass for Alpine ILX-F509

Tips

If you install speakers by your knees (e.g. 6-1/2"), cut the holes when you're doing the paneling. It's much easier then.
I installed JBL Fuse subwoofers behind my seats. They barely fit and should add some good bass!
Most stereos disable the "Setup" menu unless you have the hand brake on. Some manufacturers will let you bypass it if you simply ground the wire, but some require the brake to be pulled twice (to avoid simply grounding). My Alpine deck wanted the latter action so I bought this bypass switch on eBay for $10. It was super easy to wire up and works great.

Rearview Mirror

Resources

Master Tailgaters 10" Mirror

Tips

Mounting the mirror is pretty easy. Mounting the rearview camera is easy too. I ordered a 2" x 2" black plastic "L" bracket from Amazon and secured it to the body and camera with very strong double sided tape.
