Glow plug inhibitor switch / temp sensor question

[Drock]

So after chasing down my high idle problem by replacing both the high idle solenoid and the temp sensor. I decided to go ahead and replace the glow plug inhibitor / temp sensor located on the drivers side head. After much research I found out that a new one would be an updated version requiring a new pigtail to be wired in Part. The problem is the original one on the truck has a (1) wire connection. And the new pigtail has (2) wires. What do I do? do I just run one wire to ground and the other to the green wire? Or do I just connect them all together?.. Here's pics of both.........

If that is at the front of the engine it is the temp sensor and is not for the glowplugs. The glowplug sensor is at the the top rear at the water jacket.

Maybe try a site search for the AC Delco part number

Okay I think I found it now.. I did do a site search and that's how I found the part number. Which is #10045847, with pigtail #12101899. Now that I know where it is I'll fool with it today to see if I can make it fit. If you look a the pic it looks like there are a couple adapter fittings on the original sensor, so I'll pull it apart and report my progress. Thanks guy's

That is it. There is a bushing between the sensor and the block.

Well I got it in. It was really easy, you just have to make sure your 3/4", deep socket stays on the sensor and doesn't slide down to the adapter/spacer. But other then that it's a breeze. I thought I'd give a run down of all the part numbers for these sensors sense it took me several hours of searching both here, and the interwebs to figure out what to call them, and then to find them. Perhaps one of the moderators mite want to add these to a "sticky"??? Anyway here's the current proper name and part numbers........... (Acdelco), cold advance solenoid coolant temp switch #101546449...... (Acdelco), fuel injection idle speed control actuator #14066255..... (Acdelco), glow plug coolant temp sending unit #10045847, with (Acdelco), pigtail #12101899... Thanks again guy's for patiently helping me through this

Replaced my glow plug coolant temperature switch today, OEM switch and connector on the left, aftermarket on the right...rubber insulation on the OEM connector was largely crumbled away with wiring exposed.

how did you connect the wires? meaning did the polarity matter when hooking up the old wires to the new pigtail?
