Manual glow plug switch

I have looked high and low. This is a great site with a ton of information. But I can't seem to find the info I am looking for. I would like to go to a manual glow plug switch. Is see allot of info for a 6.9 idi manual switch. I have a 91 f-250 7.3 diesel. This new set of plugs that I need to get will be the 3rd set in 4 months. I would like it to be the last (at least for a while).

My question is this, Does any body have a wiring diagram for this conversion. It sounds like it is pretty easy. Any help would be greatly appreciated. Thank you in advanced.

Remove the white wire from the relay.
Run a wire from that terminal inside the cab and attach it to a push button switch.
Attach a wire to the other terminal of the switch and run it to a good electrical ground inside the cab.

CAUTION , the battery terminal on the relay has battery voltage at all times, use caution working on the relay, it makes a very big spark if you short out the battery terminal.

You are done.

Operation,
Turn the key to ON.
Push the button for 10 seconds.
Start the engine.

Thank you Dave after I posted that I found a post with that picture and those instructions. I was looking at a wiring diagram it looks like 10ga should be the wiring for me to use?

Actually you are only closing a relay when you use the push button, so a much lighter AWG like 14 or 16 is good.
