These photos are from the first phase of the install...

Pic 1) The power lead for the amp was snaked through the wire loom for the main battery cable. After it makes it into the engine compartment it gets its own loom and heads for the firewall grommet behind the driver's seat.

Pic 2) Access to the firewall grommet from the engine compartment is easiest through the driver's side air scoop. As mentioned in this thread: http://www.elisetalk.com/forums/show...t=wire+routing the wires going into the firewall grommet are wrapped in tape, making a pull through them difficult. The tape can be removed without too much difficulty, which is what I've done, make the pull much easier, and then retaped after the power wire was pulled through. This picture is taken through the side scoop opening.

Pic 3) The driver's compartment side of the firewall grommet, with the power wire coming through. Since I have a harness bar, taking off the firewall panel seemed like a major inconvenience... but luckily I didn't have to.

Pic 4) Wiring diagram on top of the head unit. The sleeve of the head unit was covered in dust from a spirited group drive on Engineer's Road during the "Stig Party" . Anyway the point is pin 10, the remote power pin that the amp needs to turn on and off with the head unit. Once all the RCA jacks were installed on the back of the head unit, I threaded a tinned 18 gauge wire into the empty (as in no pin) #10 slot in the connector, and taped it to the existing harness to ensure that it stays in place.

Pic 5) The dash after all the wire pulls, but before installing the looms. Note new speaker wires to the fronts, and the brown wire which will carry the remote power signal from the HU to the amp.

More to come...
