High temperature butt splices

[JHZR2]

Hi,

One of the H7 bulb sockets in my saab had some corrosion (why I dont know because it was inside the light assembly, which is pristine and sealed, with no sign of moisture), causing the ground connection to come loose.

So I need to install a new H7 socket, and the ones from amazon come with pre-stripped pigtails. That means I need to do a butt splice, and I need something that is high temperature rated (the wiring in there is 105C rated).

Ive seen some that are crimped and then have integrated shrink tubing to fully seal the connection. I think they even have some glue or substance in there to coat the physical connection (some may even have solder). The thing with all that is that this is high temperature, inside a headlight assembly... So not sure if it is appropriate.

So, any recommendations?

Thanks!

kapton tape?

I have used these before, not on headlights, I'm not sure of the temp. It says wire temp of 75c but insulating material is 125c. Its a splice that is shrinkable.

I'm just not sure how to interpret the true temp rating.

Look at Ancor connectors for marine use. They sell at least a hundred different types.

Try posi connectors. No soldering and automotive approved. They have a watertite version too. Look on eBay.

This page explains how to make a very strong crimp using solid metal connectors (which shouldn't be affected by heat):

And 3M's application guide gives heat ranges for all their heat shrink tubing:

The 3M MFP looks like it should be good. VTN-200 looks even better but it's about $800 for a 200' roll of 1/4"
