This installation documentation shows multiple options for the HO Scale LifeLike Proto 2000 E7. This installation uses the TCS DP5 decoder, T1 decoder with E7 harness, or M4P-SH decoder, and was performed by TCS.
TCS recommends using the DP5 decoder for simple plug-and-play installation.
The pictures above show the locomotive prior to the decoder installation.

Remove the"dummy" plug from the socket, then plug in the decoder so that Pin #1 of the decoder lines up with Pin #1 of the socket. Pin #1 will be designated with a "1" or a small arrow/chevron. This is all that is required for the DP5 installation unless you re-wire the Mars light.
Plug in the T1 decoder with a E7 harness as shown in the image above. Note there is a jumper between the yellow and the green pins, they are solder bridged together. This allows you to use the yellow wire (reverse light output) to control the mars light. By default, when function 0 is on the mars light will come on in reverse. For T1 decoder only, change CV50 = 0, change CV34= 4. This re maps the yellow wire to button 1 with the light on when in forward direction.
Mount the decoder behind the cab as shown above.
Above you can see the T1 decoder with E7 harness installed. Use Kapton taped to keep the wires neat and in place.
Photo above is completed M4P-SH decoder installation. Use button number one to activate the mars light, use button number zero to turn the headlight On/Off.
Important Soldering Tip
Please do not use any flux either liquid or paste on the mother board. It will damage it. Use only Rosin core solder approved for electronics use.
We recommend to use only Kester "44" rosin core, SN63PB37, .015" diameter, part number 24-6337-0007.
This can be ordered from Techni-Tool under Techni-Tool part number 488SO157
Other solder tips
When stripping wire, only strip a tiny little bit of the insulation. Strip no more then a 1/64 of an inch. When the wire gets tinned with solder, the insulation will shrink back more. Try to not expose any more wire then half the length of the solder pad at most. In no case should solder or exposed wire wire ever be outside the boundary of the the solder pad you are attaching a wire to.
