Wiring connection question: solder vs conductive grease vs nothing? 140-160

Hi all,

As part of my 1974 144 rally project I'm going to relocate and replace the fuse panel to the centre dash, roughly where the radio slot and ash tray are. I was planning on using a fuse/relay panel from a 940 because a) it has lots of extra fuse places that I need for additional electrics, b) it locates relay postions that I will need nearby and c) it is a Volvo part and I have one from a 1992 940 in front of me.

The wiring to the fuse panel attaches with push-on connections which make it really easy to rewire. My question is: is it better to solder the wire in the push on connectors - which in the massive vibrations of a rally situation might give rise to metal fatigue - or to crimp them. If I crimp them, should I use some sort of conductive grease around the wire? Most of the connectors I've seen look aluminised rather than raw copper - maybe even just made of aluminium - which might corrode with the copper wiring.

Regards
