Grounding kits
For those of you who has gotten aftermarket/DIY gounding kits, any suggestions in how to approach this, what to get, where to get, and how to install?
I don't care if some ppl say it doesn't do anything, just want to give it a try..

No one will stop you from trying. But make sure you have a way or know how to measure the before and after effect. Otherwise, might as well just tape the money under the hood and call it good. 
If you just want to connect some wires to ground, then you can get them from here. The installation is pretty much self explanatory.

If you're already set on it, it's definitely worth a try.
but he said he doesn't care, he just wants to try it out.

I installed the DIY 'kit' tonight with the help of a friend. Basically picked out some good wires and connectors from HomeDepot and connected the important places to the chasis (ground). The whole thing took about 3-4 hours, picking out the stuff, cutting, connecting the connectors, and wiring...
Will post up the pics when I get a chance later this week.

Please post some pics and review on the kit. I always thought it was a waste of time in the newer cars, but a lot of people with the G35c are doing this.

Electrical noise wreaks havoc with electronics, to include the engine controls and such. They can induce error in digital systems like the ECU and DBW. Therefore, eliminating them and ensuring a high fidelity signal would possibly reveal performance that was being squelched out by EFI in the system.
Now I know next to nothing about the TSX's electrical system specifically, so this is more just my general knowledge of the subject.

On the contrary, many new cars are fitted with a LOT of sensors, servos, and the like. With so many electrical gizmos grounding to the engine block elecrical charge is built up preventing said sensors and gizmos from working optimally.
True, the car is adequitely grounded for everyday driving. But when the engine is better grounded to the chassis and battery, the whole system works better. Many people report more power, better milage, and even peripheral benifits such as improved radio reception!

i did the grounding kit. I would say my car runs better. My main concern
was rough idle, 5AT, particularly worse after header. This is better.
There is alot of ground already the TSX but not directly from engine block
and head to the battery.
I ran from left inner fender factory ground wires, to bolt through the
alternator bracket, from that bolt inside the intake manifold to the battery.
Another from a throttle body bolt to the battery. One from tranny bracket
to the battery.
Another from the head to the battery. One from the right rear
engine block to the battery etc using existing bolts. The original
neg bat cable is still attached. I ran out of cable but need one from
left rear of head and left engine block.
I might do voltage stabilizer next.
I don't really like the contraption on top of the neg bat post and might
relocate this less conspicuous.

do you have any pics? what kit did you use? or did you do it yourself with some 4 gauge wire?

i'll tel you guys this .. those special grounding kits .. just damn wires connected at certain point on the chassis. I did a ghetto riged one and gained like 3lb of torque off of my teg .. only spent 5 bucks!!! just get normal 4 gauge .. preferable as high percent of copper you can get .. on my teg .. i just used 4 guage monster cable .. start from neg post of batter, then to passenger front strut bolt, then to intake manifold, then to driver side strut bolt, then to engine, then to front radiator support.

For those of you who did the grounding kit, did you guys get to the ECU ground? I can't seem to find where the ground of the ECU is (should be a wire going through the firewall into the engine bay), I've seen pictures where ppl connect it to the bolt on the valve cover, and was told that that was the one ground that made the most difference...
I've done the extra grounding a couple of months ago.... I THINK I noticed quicker starts and smoother idling (not so sure about any power gains). I used guage 2 wire for battery and alternator, and guage 4 for the rest, btw. These wires aren't expensive whatever material wires....so they're really stiff, good in the sense that it's not likely to move around.....bad in the sense that it takes forever to cut and bend them if you dont' have a heavy duty wire cutter...

pictures of ground wire kit
First one is overall view of engine bay.
close up of this wire from the left inner fender factory ground point to
alternator bracket, and another from alt bracket running inside of intake to bat.
Wire from the throttle body loops behind intake pipe to the battery.
Wire from Alt to battery is running past there.
Collector on top of battery, factory neg bat cable is attached
Behind and left of the K$N sticker a wire is attached to
the tranny bracket, where a factory ground wire spans to the frame. A wire is going to the right end of the head, and a wire is running to the right rear of the engine block.
The wire running to the right rear of the engine block is attached at the
clip for the oxy sensors harness. The part that this is attached
spans the tranny and engine block.
I feel I need one long cable to the left rear of the engine block and left of the
head but the alternator bolt is also covering the left side of the engine.
The car, it is overcast, lighting not good. The pear bloomed last week.

excellent pics. the diy sounds like a good alternative for an inexpensive ground kit, but I don't like how it clutters up the engine bay. that's a tough tradeoff.

from collector to neg bat clamp.
I would do black wires if I could do it again. The end terminals are readily available and wire lengths can be custom fit, using tie wraps etc to clean it all up.
I just want to get the thing on an see what it would do, it is better.
Next I have clean it up.

install, idle got rougher. It's the usual complaint about A/C on and I think
worse in the 5AT under load in Drive. Dealer said they all do it and refused to
up my idle 50 RPM. This helped that
problem, just a little roughness with A/C on very nice w/o A/C.
Thinking about it the worst noise is from the spark plugs and alternator.
The worst power drain is from the headlights.
Rigging up someting extensive to cover the head is probably the best
thing. Maybe I'll span to 4 intake manifold bolts to fully cover
the head. I only have one intake manifold bolt covered on the right side now,
I have 4 attachments to the head but three of them on the right side
and not distributed.
Does anyone know where the headlights factory grounding is, I want
to be sure this is covered. That's why I hit the factory ground on the
left inner fender but I'm not sure this is headlight ground.

While installing my wiring for my fogs, there are several grounds under the bumper that are obviously not visible like those in the engine bay.
f you have the regular covers where the fogs belong, remove that. Inside the hole look towards the center of the car and up a bit, you should see three wires attached to one spot for a ground. I could be worng, but it might be another option for where the ground might be for the lights, being closer than the one you mentioned.
Hope that makes sense.
