Question Manual glow plug controller??

There's a product on ebay, currently item #280172706732, a manual glow plug relay controller. As I understand it, this allows you to manually control the time your glow plugs are on. Seems to make sense, especially when it allows you to not run glow plugs when restarting a hot-warm engine which he claims will extend the life of your glow plugs.

Any thoughts? Comments??

He is, therefore, a total uneducated newbie who, at numerous times in the future, will be posting questions within this forum that may, without any intended malice, result in painful groans, crippling laughter, possible gastric distress, and replies which, hopefully, point him in the right direction, eventually making him as knowledgeable as the responders themselves, who, at one time, suffered from the same lack of knowledge. In addendum et al, responders who resort to the use of abbreviations, truncations, or other forms of motor slang may leave said newbie in a state of dazed confusion, frustration and/or misdirection which may result in air filters attached to exhausts, glow plugs wired to stereo speakers, etc, etc. At least he knows enough not to buy a Duramax.

yep. add abut $5 worth of wire and switch to the $25 gpr. i have seen that guys auctions for a while, and the only thing that makes his auctions worth the price, is the 2 year warranty, imo.

Thank you. Which 2 wires would be disconnected and wired to the momentary switch?

I can't remember the color (though I think it might be red) of the trigger wire from the ignition to the relay. Easy way to find out is to use a multimeter and have someone turn the ignition on while you check the small wires going to the relay. The one that is cold with ignition off and hot with ignition on is the trigger wire. Just cut that wire and splice a momentary switch into that line and mount the switch in the cab.

It's the small wire on the left side of the relay. Disconnect that one and tape it off. From the post you just disconnected, run a wire into the cab of the truck, through a spring loaded push button switch and from there to ground. Done.

Got me to thinking after reading this post. Since I intend to add a remote start, that the computer would still need to control the glow plugs when cold for the remote start. Would be easy enough to run it through an on-off-momentary switch for full control. Can even throw on a LED to see when the GPR is activated like in the other thread.
