Greetings to all.

I recently removed both my ECU and immobilizer, so to have them reflashed to ROW specs. In so doing I needed to remove a variety of plastic multi-pin electrical connectors, and I was pleased to see no signs of corrosion / overheating / distress for any of them. So that's all good.

Looking forward, upon reassembly, what is the consensus of the group as to applying a preventive material to these terminals, done so in the name of trying to prevent any future mischief due to a bad contact / water infiltration / what have you?

A spotty connection at one of these pins, which would result in a wonky operating condition or error code being thrown, could lead to an infuriating search as it would be non-obvious.

Some possible thoughts that I have had would be to work some copper dielectric grease down into the pin sockets before assembly. Or to spray the contact points with a silicone spray lube. Or to wipe down with a silicone grease. Or to treat the pins with a standard light petroleum-based oil.

Or else, just leave well enough alone, and reinstall “dry” with no treatment.

Thoughts? Opinions?

Thanks - DM
