where is the maf normally grounded? do you know
what would make it a not so good ground over time?
I must admit i am a little hesitant to work on the
 electrical system on my car aside from the
stereo. where would you say is a good place
to run the ground? and should i cut the original
ground wire. or just strip a small section of wire?
sorry if im askin alot of question im just
really nervous about doin this since reading
about that horror storie of the guy that fried his ecu.
thx for all the great info so far!!
