Looking into the guide on this process, gonna do it first day i have off
But i have a question, what exactly is the point of running a ground on both sides of the wire?? Is it ok if i just ground the side in the engine bay?
Also, i read somewhere about crimping the connections to the ecu adds extra resistance to the wire and can throw off the ECU's reading. Would soldering both ends help this any?
Soldering doesnt seem that difficult, but this will be my first time doing it, any tips?
