I just got a solder gun, solder and a black mustange today and decided to try and do the pcb mod and jump the resistors (think that's the correct terminology) on my older car. Oh boy did it go bad. My inaccuracy caused most of the nearby resistors to fall off, and I think I burned the PCB itself....oh crapomingo. At least I have the mustang. And before that PCB experiment, I was able to solder back on the antenna. And at least now I have a battery for dual batting.
