OK, I got the new timer/clock, installed it, and it works. I'll try the cleaning cycle soon. I did not have to fool with the ground wire since the double oven has four wires connecting to the Common/Neutral (5) terminal.

I had to enlarge (slot) two mounting holes to move the new timer about 1/8 inch to the right to line up with the holes in the glass. I had to use all five jumpers to extend wires.

I cut about 1/2 inch off the end of the push buttons and crimped them a bit to make them more flush with the glass (the original length left them sticking out too far for my taste). They also come out more easily without the barbs on the end which is good if you have to service the clock again.

The wire colors for the double oven are (when two wires are connected together I show it as color__color):

Old timer:

Terminal Usage Color
1 L1 red__red
1 L1 pink
5 Common/Neutral white__white
5 Common/Neutral white__white
2 Output1 unused tab
2 Output1 yellow (big)
4 L2 blue
4 L2 blue__blue
3 Output2 black
3 Output2 black

The new timer numbers L2 as 3 and Output 2 as 4 so all the wires are the same except the last four wires:

New timer:

Terminal Usage Color *Jumper
1 L1 red__red
1 L1 pink
5 Common/Neutral white__white *
5 Common/Neutral white__white *
2 Output1 unused tab
2 Output1 yellow (big) *
3 L2 blue *
3 L2 blue__blue *
4 Output2 black
4 Output2 black

I had to jumper the wires marked above with an asterisk (*).

I put the supplied heat shrink tubing on two jumpers and used a hairdryer to shrink it. I had to tape the three tripple connections because the heat shrink tubing was too small.

I'll post pictures soon.
