I have an Intermatic T103 DPST timer installed now (120v). The clock mechanism has failed. I bought Tork 1103 guts to replace it. The wiring is a bit different. Can u map for me which wires go to which terminals?

You have the T103 timer rated 120-240. The clock motor part of timer is 120Volt. This is a very versatile timer, but confusing for non-electrician and electrician alike.
Solve problem by converting timer from T103 to the 240V T104 by changing clock motor from 120V WG1570 to 240V WG1573.
Buy wg1573 clock motor at WW Grainger or drillspot etc.

This simple fix is intentionally designed by Intermatic so their timers are not only adaptable to all electrical needs, but also can be maintained to last 25 years by replacing clock motors and trippers as needed

Copy following link for T103 timer wiring options:
The clock motor is 120Volts, but clock motor can be changed from WH1570 to WG1573, and this action changes 120V T103 into 208-277V T104 timer:

13 years is good run for clock motor. Timer will last longer than clock motor.

You posted under T103 Intermatic 120V timer.

Sounds like you wired the timer wrong:
Timer has 120V clock motor and requires Hot from breaker on terminal 1, and Neutral from breaker on terminal A. This will power clock motor.
If you have any of the wires reversed, timer will do what you describe.

Clock motor can be replace with identical 120V clock motor from Grainger
http://www.grainger.com/Grainger/INTERMATIC-Time-Clock-Motor-1PNK1?Pid=search

Timer mechanism snaps out and clock motor is located on back.
Remove clock motor with star screwdriver tip

Connect new clock motor wires to DIFFERENT terminals than before.
Old clock was connected to terminals 1 and 3
New 120V clock motor is connected to terminals A and 1

Wiring for 120V T103 is shown on link below.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T103
White neutral wire must connect to terminal A
Black hot wire must connect to terminal 1

T103M is 120Volt timer that can handle all the Christmas lights.
Minimum on-off time 1 hour.
Rotate dial until current time lines up with silver pointer.
Set on-off trippers on dial.
Let's go step by step.

1) T103 has terminals A 1 2 3 4 >> terminals are also called poles
DPST (double pole single throw) and SPST (single pole single throw) are two different ways to wire this particular timer.
T103 timer can be wired numerous ways... but your project is not complicated.
DPST means timer turns off two terminals/poles (double pole) with each click/throw of timer switch (single throw)
SPST means timer turns off one terminal/pole (single pole) with each click/throw of timer switch (single throw)

2) T103 timer is ST single throw, all the lights come on at same time. So this timer is 1 channel.
1 channel timers are either ON or OFF and everything turns on-off at same time.
You cannot stagger on-off times with 1 channel timer.
If you want upstairs and downstairs lights to come ON at different times, you need two timers .. or a 2-channel timer (which is different ballgame).

3) T103 timer has 120Volt clock motor that is connected to terminals A and 1.
Look at timer and you can see small white wires connected to A and 1 terminals that power 125V clock motor.
When wiring this timer, your wires from 20 amp breaker box connect to terminals A and 1.
Black hot wire from breaker must connect to terminal 1
White neutral wire from neutral busbar must connect to terminal A
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T103
http://waterheatertimer.org/B220C.html

4) Terminal 1 must be hot so when timer switch clicks ON, it sends power to terminal 2.
Your load wires connect to terminals A and 2
I made simple drawing of SPST option showing how to wire T103 to 3 receptacles.
Fixya downgrades image so it's hard to see.
Hot wire to terminal 1
Load wire to terminal 2
Neutrals on terminal A

If you want to wire timer for DPST, which is necessary for loads exceeding 2 horsepower (1500 Watts) on each terminal
Notice black jumper wire from terminal 1 to terminal 3
Notice all white neutral wires to terminal A

I made third image for guy who was wiring high amperage blowers, that show wiring for two T103 timers. Having two timers would let upstairs and downstairs lights come on at different times.

T103 Intermatic timer has 120Volt clock motor and can control 120V or 240V Loads.
Wiring for timer is shown on following link:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T103

Troubleshoot T103:
1) Manual override is working correctly, and it snaps crisp and clean, and Load turns on-and-off.
That means timer is basically good.

2) Next look to see if yellow dial is rotating.
If dial is not rotating, then 120Volt clock motor needs to be replaced.
Take photo of wiring and mark wires before starting.
Remove two white wires connected to screw terminals 1 and A.
Snap timer mechanism out of box, clock motor is on back of timer.
Use small star screwdriver to remove old clock motor.
Reattach white wires on terminals 1 and A, tighten screws very tight.
Reset current time: lift and rotate dial until current time lines up with silver pointer.
Grainger sells 125V clock motor:
http://www.grainger.com/Grainger/INTERMATIC-Time-Clock-Motor-1PNK1?Pid=search

3) If dial is rotating, but gets stuck at certain times, or runs slow, then replace clock motor.

4) If dial is rotating, and trippers are attached to dial, but timer does not turn ON, then trippers are worn down and need to be replaced.
Grainger sells the T103 trippers
http://www.grainger.com/Grainger/INTERMATIC-Timer-Tripper-2E054?Pid=search

5) How Intermatic mechanical timers work:
Dial with ON-OFF trippers is rotated by clock motor.
Trippers on dial contact ON-OFF lever.
ON tripper pushes lever one direction.
OFF tripper pushes lever opposite direction.
Lever moves electrical contacts on back of timer that turn Load ON-OFF.
Manual override lever clicks back and forth with each ON-OFF action.

1) Clock motor needs replacement:
Link below shows timer and wiring manuals.

2) 120Volt Clock motor sells for $43 at Frontier lighting
http://www.frontierlighting.com/product.jsp?part=10431&process=search&show=&ID=,Photo.Cells...Time.Controls,Replacement.Motors

3) New Tork 1103 sells for $55. Just swap out insides without changing box.

4) Intermatic crossover for Tork 1103 shows Intermatic T103 timer.
Amazon sells T103 for $50
