DIY: Groundwire Kit - Toyota Yaris Forums

bst82551 · 05-19-2010, 08:49 PM

I did this earlier this week as well and it turned out better than I'd imagined. The DIY guide helped A LOT. One definite issue I had was getting the adapter off of the negative battery cable. I ended up sawing it off, but not before slicing my knuckles a few times trying to get it off with a wrench. This install was very easy and would've only taken about 45 minutes if it weren't for that pesky adapter on the battery cable.

Anyway, as far as results go, I can't say for sure that it's all based on the new groundwire kit, but my car definitely rides smoother and accelerates better, particularly in the mid-range RPMs. I also feel smoother shifts from my automatic transmission.

However, I absolutely have to note that part of this may be due to the fact that I had the battery disconnected for about an hour, which reset every electrical component in the vehicle (including the engine control unit). So, I would've experienced a smoother ride either way from simply resetting the ECU, but I've reset it before and don't believe the results were this drastic in the past. I haven't had a chance to see any difference in fuel efficiency yet, but it certainly wouldn't surprise me to see an extra 1 or 2 mpg.

P.S. Kac, is your air filter just laying out or do you have some strange new intake I've never seen before? I see your sig says you have a modified air intake box. Is there a DIY guide or any more info about it?
