DIY - Grounding Wire for Hyundai Coupe
The use of grounding wires enhances your cars earthing system, and some people
report that they car feels smoother or that their lights are brighter.
The DIY below is on a V6 Hyundai Coupe, but the same principal can be applied to any
car.
Thanks to Mark (m455954) for the DIY
Just finished installing the grounding wires and I know there was some interest
in a DIY for these so here goes.
The wires are 4 gauge audio grade OFC copper with gold plated crimped ends.
The first one augments the stock ground strap to the negative battery terminal.
I had to modify the original terminal as the nuts wouldn't come off.
The second wire goes from the negative terminal to the engine block.
The third wire goes from the engine block to the back of the intake manifold
where the throttle & cruise control cable bracket attaches.
The fourth goes from there to the mounting point for one of the brackets that
one of the plastic engine covers normally mounts to (I got rid of the engine
covers ages ago).
The fifth goes from there to the bolt at the top of the A/C compressor (bottom
left of the engine bay)
The sixth replaces the stock grounding strap that goes from the intake manifold
to the firewall (top middle back of the engine bay)
and the whole thing looks like this
It's hard to notice exactly what difference this has made as I've also changed
out the intake manifolds for ported & polished ones, but overall the car
feels so much more eager now.
