This installation is for HO-Scale Athearn F59PHI DCC Ready uses TCS T4X Digital Decoder and was performed by A.G.

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

The three upper pictures show beautiful and very detailed Athearn F59PHI prior to the TCS T4X Installation.


Remove rear coupler and gently lift the shell off of the locomotive chassis being careful not to break light wires.


We are going to use our T4X decoder which means that 9PIN JST socket will be utilized.


Remove the 9PIN JST "dummy" plug as shown in the picture above.


Insert the T4X into the 9PIN JST socket in exact way it is shown in the picture above. Reattach the coupler, shell and the locomotive is ready to run.

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.
