The autoloc stuff is great. I bought a kit from them and installed
it on my wifes miata 4 years ago. Not a single problem.
I haven't done an install in my 914 but it was a bit of pain in the miata.
My only complaint now is that since then autoloc has become
very popular and their prices have more than doubled since then.
These guys have similar products for substantially less money:

module, and you can even order a kit that includes a keyless
entry remote.
The "universal" type kits are the way to go since they include
the lock/unlock switches inside the actuator (no lock/unlock buttons)
which means you can lock/unlock the doors from the key or either
of the manual locks, even keyless if you spring for the keyless option.
