Lost wire not car won't start

I never do such home-made relay wiring and the electrical tape hides problems. You can buy wired bases for standard Bosch relays (I have a box of them from ebay). Even better, you can get a relay & base w/ integral dust cover. But, in my old Mopars, I installed an underhood relay/fuse box from a late 1990's Jeep w/ ~13 relays for more elegant and reliable wiring. You can see it (black box) on the L fender in my 65 Dart avatar.
