Im swapping in a sohc zc into my crx and am also doing a pretty large dual 1000 watt amp system + a few other high power drawing items. Would it hurt to use 4ga wire on all 3 grounds on my ef? Like it doesnt hurt it right? I have a lot left over and just want to make use of it. Thought this would be a good time

Also does anyone have a diagram on where all the grounds are on a sohc zc? Only one Ive ever really seen and noticed was the one from the valve cover

Thanks

 

no it wouldn't hurt anything. if anything it would only help think of the jdm wiring kits same idea

 

There are 3 stock grounds...

Valve Cover > Chassis
Neg Bat Post > Chassis > Tranny
Wiring Harness > Thermostat

You can't really replace the thermostat ground since it is inside a wiring harness, I wouldn't touch it.

 

I upgraded my grounds in my prelude to 8 AWG with brass ends. I noticed more solid starts and my dash lights seemed brighter at night. In any case it really can't hurt to upgrade from those old stock grounds.

 

That is something I always do when I buy a new car.
Its a good cheap improvment so why not do it.
