4. Connect the tape to the new faceplate circuit board assembly:
a) If this is a Mk3 TLC Meter, press down on the white

terminals on the circuit board and insert the tape leads.
Release the terminals and the leads should be secured.
The lead on the bottom of the tape (numbers facing up)
is inserted into the terminal labelled BOT on the circuit
board, and the top lead into the terminal labelled TOP.

b) If this is an Mk2 TLC Meter, with a Molex connector

on the tape leads, remove the Molex connector by
pushing out the two pins. Cut each pin in half (see
image below for correct location). Use pliers to flatten
the remainder of the pins against the tape lead, so it fits
easily into the terminals on the circuit board. Connect
each tape lead to the new circuit board assembly, as
described above in step a.
