It does get some engine heat, but it's out of the sun, so it might be ok. Here's an idea, Though. If the existing part can be slid out of it's home, on the connector how about cutting the existing peg/post/pin off, drilling a hole and pushing a new regular pin through from the back?
I like that idea. Not sure if it's possible with how the clip mounts to the connector, but I'll definitely give it a look.
