water tight tecs?

[Fred Miranda]

Ok David, didn't know Haltech was plug in.

A word of caution though re: washing down engine bay with a TEC in it.
A TEC2 has 2 halves electrically connected by a 20odd pin connector.
This thing isn't sealed, get some moisture in there and you'll have some
real problems.
