alternative mod to replacing oem harness connectors
 

This mod isn't for everybody, but my old connectors are brittle, and break. So I've soldered in some wires directly to the sensor pins to make pigtails, then I am able to use generic weather pack connectors on just about anything. I've crimped on matching weather packs for the harness itself not shown in this picture. I have also protected the wires in shrinkable fabric, and sealed the pins with silicone to keep water out and to dapen vibration.

Looks good bro. I will probably be redoing my whole harness this coming spring. I am NOT looking forward to it.

This could be cost effective for someone who has eliminated most of the stock harness - ie. non-seq. or single turbo - but would be expensive and time-consuming for soemone keeping most of the stock connectors. Those weather-pack connectors are very expensive. It looks like there is more potential for problems since there are more connections and joints. Also, how do you replace the sensors if they go bad?

I did the exact same thing with my air intake temp sensor.
I got some weather packs from O'Reilly autoparts for about $1 each, IIRC. not too bad for a high quality connector. When I went, the guys had no clue that they had them so we had to dig through some books. We found them in the borg warner (BWD) book. I wish I still had the part numbers...

Thats why I say it isnt for everyone, I'm running non-seq so it does keep things simple. Weather packs are only expensive if you buy them individually at electronic outlets.
waytekwire.com sells them for cheap in quantity
Go to "Products" | "Connectors multi-pin" | "Packard Weather Pack"

I understand your concern about having more joints, but I trust this setup more than I can for the rotting, 13 year old stuff that was there. The silicone is the most important step for a long life. I am also able to cut back several inches on the harness to get rid of some of the old, brittle wire.

I also plan on making a mount so that the connectors can be clipped in place, rather than flopping around. These weatherpacks can accept a tab to clip on to.

Sensor rarely go bad, they are outliving my harness, and if they do, I have no quarrels with modifying them as I have done with the old ones.

how long ago did you do it, how well is it holding up?
