I just picked up an FC and heard there was a lot of grounding issues with it. I was wondering what should I do first before I pry anything open. Currently my stereo has a mind of its own and works on its own time as do my speakers. I already checked my fuses, which none are blown, and was just wondering what can I do?

 

The stereo issue is likely due to poor solder joints in the stereo, amps, or both.

Aaron,

According to http://www.aaroncake.net/rx-7/grounding.htm, you're stating that you can further ground the ecu by adding additional grounding wires at "3G and 3A (all years)."

According to http://www.4shared.com/office/R50zZjNn/ECU_Pinout.html, the 3G and 3A pinouts seem to indicate something other than ground. (?)

So... are 3A and 3G according to the pinout diagram still the best places to add additional grounds?

Thanks in advance.

 

I'm referring to an FC, you posted the ECU for an FD.
