diy: 4afe engine ground wire

[wakdjoko]

dear toyotarion,

one of my fren who uses wira 1.5 just diy ground wire himself n the result is very good.

the acceleration is increased, engine felt much more power.

so he recommends me to diy my 4afe as he did.

if u guys got any info to diy the ground wire, pls share it with me.

i've searched the internet but cant found any info about grounding points. maybe they use diff terms.

thanks a lot!
