DIY: $15 grounding kit

[Saskatoon Subaru]

here's my $15 grounding kit. anyone with 10+ year old OEM grounds that are corroding and starting to turn green needs to do this. 90% of all 10+ yr old car electrical problems are because of a bad ground signal.

here's what you need:
one 12" 4gauge top post style battery ground $5
one 32" 4gauge battery cable $5
one 16" 4gauge battery cable (optional) $5


the install:

12" top post goes from the battery to the OEM radiator support grounding point


32" cable goes from the battery terminal to the tranny ground
16" cable goes from the tranny ground to the firewall


here's the 32" cable connection to the battery terminal


if you really feel ambitious, you could take this a step further and connect a wire from the tranny ground to the alternator mounting bracket, but it's not essential.

the engine starts instantly now, the door locks and windows work twice as fast as they use to, and the engine seems to run a lot smoother.

could you repost pictures plz

Since this is a fresh topic I wanted to add something.

MAKE SURE YOUR WIRES DO NOT INTERFERE WITH YOUR THROTTLE.

Seriously, wire tie any wire that is near your throttle body to keep it from moving. Recently I took a hard corner at partial throttle and during the turn the wire slid over and over top of the throttle arm where the cables attach. This resulted in my car not being able to close throttle which resulted in several minutes of panicked trouble shooting trying to figure out why my car wouldn't stop accelerating or bouncing of the limiter if I clutched. I was relieved to find the problem was simple but needless to say if I'd been in heavy traffic this senario would have been a bit more tense.

Seems kinda 'duh' I know, but I wanted to make sure I shared my experience so others can learn...
