start using inexpensive wires and a decent cap. this way when you toss the wires and cap all at once it wont hurt so much.
now the fun begins. find a plastic container that is about 2 inches larger than your dist cap. cut 10 holes in it for the wires to pass through. make sure they line up nice. feed the wires through the cap and a breether tube as well. plug everything in in the order it needs to be. MAKE SURE ITS CONNECTED WELL. a bit of dielectric grease and then tape them down with electrical tape. now push the cover over the cap and will with self expanding foam.
RTV this down to your distributor being carefull to not get to much inside the dist.
like i said use inexpensive wires...
