Remove the 4 buffers marked with the blue arrows, they just pull out. Remove the 2 screws, red arrows, from the underside. The body should then lift up off the chassis.
The decoder blanking plug, the arrows shows the position of pin 1. Lift the plug upwards to remove.
Fit the TCS DP2X, as shown, noting the orientation. Test installation on your test track before refitting the body, which is the reverse of the removal procedure.

Important Soldering Tip

Please do not use any flux either liquid or paste on the mother board. Over time, the acidic properties of liquid or paste flux will begin eating away at the fiberglass PCB and will damage it. Use only Rosin-core solder or no-clean flux approved for electronics use.

TCS recommends the use of Kester "44" Sn63 Pb37, .015" diameter Rosin-core solder. Kester part number 24-6337-0007.

You can order this solder from the following retailers:
Digikey - PN:KE1110-ND
Techni-Tool - PN:488SO6775

Other solder tips

When stripping wire, only strip a tiny little bit of the insulation. Strip no more than a 1/32 of an inch. When the wire gets tinned with solder, the insulation will shrink back more. Try to not expose any more wire than 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.
