And I have to replace/repair some wiring due to fire. At the track, I used what I had to get the car back on the track. Now that we're back, and we have a break, I want to repair this for longevity. My plan is to cut out all the jumpers/splices I installed (in less than an hour mind you to make the race) and re-strip, then solder and heat shrink the connections. Better ideas? Some of the wiring is 14ga, some 12, and others are just for signalling and is 20ga.
