No watch needed. I energize the glow plugs for 10-12 seconds when temp
above +32 degrees, and 15 seconds below -32 degrees and plug in overnight -0
degrees and do 15 seconds in morning. One, one thousand, two, two thousand
and so on. Just count. I never had problem with plugs since conversion 4
years ago. Also, my seatbelt light stays lit for 8 seconds, good indicator.
I would worry more about putting in cut-off switch to protect against
solenoid shorting, or starter going bad.
FWIW- if starter or solenoid shorts and wires start to burn, cut positive
side of batteries first. When wires burn they short and make ground.
Cutting ground side of batteries won't stop it. I know this from
experience.

Jeff,
The manual glow plug switch conversion is the way to
go...simple...eliminates the trouble prone glow plug controller card and
easy to use. BUT, one item was missing from the repost. It is very easy to
burn out the glow plugs if you run them too long. If you have a digital
watch that counts seconds use it and keep track of how long you have had
the button depressed when using the glow plugs. The reason is
overheating...they expand, burst and then no longer heat up. You then
discover what a pain and expense it is to replace expanded glow plugs...it
can require the removal of the heads to remove the bad glow plugs.
