At Jab-Tech.com.....The wire stripper will do 24AWG stranded very well, VG tool. The rachet Molex crimper they have is very good kit, he should have a full selection of dies for it by now.
The dies are removable and five other types can be installed for different crimping needs.
Both are made in Taiwan and are of quality manufacture, plus reasonably priced.
Allelectronics.com for good cheap heatshrink.
Action-electronics for Molex pins,male&female. They carry most all shells you will need. They are worth a look. They carry near all you need for your cable runs. They are not the cheapest to buy from but the product they offer is of good quality.
Harbor Freight for a decent heatshrink gun, 600 and 1000 watt settings. Got mine on sale @<$10.
Caig.com...Get some ProGold and use it when the new connections are made-up and there will never be a problem with resistace caused by moisture. I use it on all batteries and life is noticable extended because of lowered resistance.
I'm not expert about any of this but have bought from all five of these venders on-line.
