There are many paths to the same goal...

My 914ev partner-in-crime Randy (who purchased the very first 914 AC kit from ElectroAuto) e-mailed me some photographs of how he's wiring up his terminal blocks and relays. Here are some pictures and descriptions from his 914 AC conversion. (Thanks, Randy!)

Excerpt from Randy's e-mail:

I've also started on the wiring kit. I looked at the instructions
and decided to rearrange things (typical). I put an aluminum project
box next to the controller so that most of the connections and the
relays would be better protected. I also fabricated a plate and a
box to replace the original relay board and am putting connected
there for tying into the harness. To bring the wires into the trunk,
I was able to take advantage of a slot I cut for the Camp 914 rear
trunk shock kit. I've attached a few pictures...

This is where the original relay board went. Inside this box are
connectors to bring the wiring harness and the potbox back to the
relay/terminal blocks in the rear trunk. Still need to try back the
extra length of wires.

This shows the wires between the boxes coming into the rear trunk.
The slot was cut when I installed the Camp 914 shock kit. I may have
to enlarge it a little bit. Note that I was able to bring the plug
between the motor and controller around here with enough length to
make it. That means the only cables coming through the trunk floor
will be the the big motor controller and the battery wires. The two
lower wires are actually loose strands that I put through clear
shrink wrap to make my own harnessed.

This is my rear trunk. The small aluminum box has the terminal
blocks and relays. You can also see that I had gobs of extra cable
length between the motor and the controller - so much so that I would
like to think about cutting them short and replacing the connectors.

Inside of the aluminum box. I've run all the wires I can (until I
get more instructions from ElectroAuto). Note the shrink wrap on the
connectors - something I always do with crimped connectors.

Here are some pictures of the shunt (including one showing where I
am thinking about installing it).

The shunt is a very, very low resistance plate with two bolts on
either end. The large bolts are for the battery wires while the
small bolts all the current meter to measure the voltage drop over
this tiny resistance (and thus the current).
