So DELInstallations, do you favor surface mounted contacts over the recessed ones? Unfortunately, i bought the 'cheap' ones, not the screw terminal contacts. Wish i had read this. I am using the ELK gel contact crimps tough, that should help with corrosion over time. Any advice on using these? There is little literature with them. The recommend folding wires back and stuffing them in, but they did not fit, unless you strip the wires first? Any other crimp recommendations?
