I am having some electrical problems lately (grounding issues, speedometer not working sometimes, brake light coming on for a few second at a time, etc.). I am also going to be swapping an engine soon, if I can finish building it, which means I will have to wire vtec and knock sensor. So my question is will swapping a new Ex engine and cabin harness take care of the vtec, knock sensor part of the problem. I know it will fix the electrical problems because I am pretty sure all the problems stem from shorts in the wires or bad plugs. Plus it would be nice to have new wires instead of the 16 year old ones that are in there now. Any opinions or advice would be helpfull.
