I'd guess it's using the female part of bullet connectors on the glow plugs.
It sounds like it's the best way to go. Most of the others seem to have trouble keeping a connection for whatever reason.The more I deal with other connectors, the more I like the idea of using these, along with 4mm silicone hose, to hold them on with.
YES!Someone needs to make female bullets with a spring clamp like a spark plug cable
The silicone hose is very stretchy which is what holds the connector to the glowplug when I built my harness that way I used electrical lubricant which made the install easier but didn't hold the plug as well. I'd imagine spit or anything that would evaporate would work better. I'd show pictures but the harness was destroyed when my truck caught fire (unrelated to the harness)Ok, I have the wire. I have the bullet connectors. I have the shrink tube. (Tons of extra). I have the silicone tubing. I have the cool looking button that lights up only when you push it and it is actually working. I even have the 600 amp solenoid. (And I have 8 beru GPs ordered and on the way, just in case.)
I will start on building my own harness soon.
A quick question though... That silicone tube seems awfully small for this purpose. I may find that it fits well. I don't know. Question is, what can I use as a lube to help get it on there... That will eventually go away on it's own? Don't want to use silicone grease...
