Vintage Snazzy (so my adult children say)
Crimp worked better than solder and shrink tubing?
I started with heat shrink, but being next to the engine...I installed myself as well and really like the instrument and ease of installation. I removed all of my old analog gauges in the process. Accurate fuel level metering and fuel calculation add immeasurably to safety.
But I had the same connection failures on a couple of probes. One EGT probe was giving me a particularly bad time, only lasting a few hours after each of my numerous attempts to address it. I even had staggered the connectors as you mention, and tried adhesive heat shrink on the individual wires as well as around the bundle, but I still suffered failures. After contacting EI for a solution, they sent me a kit with ferrules and a crimp tool to try (mentioned in another thread), and I haven’t had a failure since.

It was that much that it deteriorated a solder connection? I wouldn't have thought. And that's why I still learn a lot from this place.I started with heat shrink, but being next to the engine...
No solder connection. But the heat shrink deteriorated and the wires started to move around in the air in the cowl and I got a loose wire from the movement.It was that much that it deteriorated a solder connection? I wouldn't have thought. And that's why I still learn a lot from this place.
That hi-temp silicone rescue tape works great on stuff like this.No solder connection. But the heat shrink deteriorated and the wires started to move around in the air in the cowl and I got a loose wire from the movement.
The not so pretty, but effective solution for me:

I didn't even know those Ferrules existed! I need to try one of those kits.
