whats ghetto is soldering shit when u don't know if it works..
it not going to hurt it to test it out on the battery for a few seconds.
it always pays off to try things out, test fit things, mock things up before you go tightening the bolts as hard as you can, or soldering wires..
don't take any this the wrong way, just trying to offer some valuable advice that was given to me, Measure Twice, Cut Once.
