Well having owned scores of 1.9's all of mine get soldered connections and heat shrink for strain relief (in 2 stacked layers usually.)� And I have a real AMP crimper for proper crimping for an oxygen free aerospace grade connection.� I still solder these, as I have countless other connections in countless VW's.� If you don't want it to wick significantly, only use a touch of solder to fill the connection, and then do something for strain relief.� And use real solder, with lead, it is still out there and you will thank yourself.� Be prepared as these often have been carrying stray current and the first few inches of several of those wires may be in bad shape indeed, may need extended.� Cut back till you got clean flexible wire, solder the extension, heat shrink, etc.

I actually on old (bus) harnesses often acid dip connectors to clean and etch, solder, neutralize with baking soda solution, apply NO-OX-ID and thereby salvage a factory looking connection.

On a 1.9 replace the ground strap while you are at it.� Clean the head very well, NO-OX-ID or your favorite goop.

Doing so on a 1.9 will solve all sorts of FI gremlins that they are prone to when they age.

Certainly David's points are all very valid, and in the aerospace world indeed all very correct, YMMV.

If you do, you're liable to create a hard spot in the wire (as the
solder wicks up the strands) which is subject to fatigue and breakage
from vibration.� People who solder for NASA get around this by using
beryllium-copper anti-wicking tweezers on the wire as they solder
each joint.� You may want to think carefully about strain relief.
