i think the first thing you should do is invest in a soldering iron and some waterproof shrink tube. those wire crimp things are not a positive conection and will only get worse over time as moisture finds its way into the wires. wire connecters like that have no place in automotive applications as far as im concerned.

if your real lucky maybe that will fix the issue but my guess is you may have damaged the computer.
