There are. a couple of ways to solder it on .One is to melt the solder in the lug first then slide the cable into the solder filled lug while it is still melted and cool quickly with flux.The other is to drill a small hole in the lug end close to where it attaches to the starter.This will allow u to fill the lug with solder while at the same time keeping the heat away from the insulation.Be sure to clean wire and inside of lug with a red pad and flux prior to heating.The flux will help draw the solder into the lug.Thanks! I looked at the lugs from your links. I have been unable to find a "Y" lug similar to the original Ford one. Trying to calculate the current carrying capacity of the single wire fed by both wires is beyond my pay grade. I have some work experience crimping 1/16-1/2" stranded wire lugs and cable fittings, but I do not have the crimpers necessary to firmly and properly attach the crimped lugs to the wire while it's in the car. Therefore, any new lug will have to be soldered, which means putting a lot of heat into the cable ends and undoubtedly damaging some length of the woven cover that protects the wires.
