its safe yes.. and theres a cover that goes on there that i took off to take picture.. it snaps on and off .. it had to have some cut off of it to fit back on after i upgraded the wires.. also you could pack with dieletric grease
I went to wal mart and in the auto section they had a battery area w connectors and wires n junk..
1.they have the extra stud for the pdc.
(i just used a bolt and ground the head to fit)
2. lengths of 2ga wire with ring terminals on both end 55"
(i think i bought 3)
3.. and 2 boxes of ring terminals 2ea. box..
(got biggest i could and trimmed wire to fit)
4. Advance auto parts had the fuse.
(i walked in and said whats the biggest fuse you got)
I used the existing ring terminal on one end cut the wire to length and then crimp rimg terminal to other end (i bashed with hammer on top of bolt head lol).. then tape nice and good!
and heres where i ran the wires.
Negative
1. - batt to firewall (replace stock location throw out stock wire)
2. - Block to firewall (replace and throw out braided crap ground)
3. - Batt to group of ring terminals grounded behind alt.
- Left connected stock batt neg to (heads behind alt in the bundle)
Positive
1. + Batt to starter (left old power run hooked too)
2. + Batt to P.D.C. (right stud)
3. + from added Stud in P.D.C. to Alt + (left old power run hooked too)
left connected stock batt + to (heads behind alt in the bundle)
left connected the stock batt + to p.d.c. right stud then hooked
stock p.d.c. to alt + to right stud as well ..
connect the two studs with the fuse ..
Cut little plastic cover for p.d.c. to fit back on and voila!!
I reccomend grabbing some rough sandpaper to rough up where connections will be made.. and i added some washers to some of my connections to ensure good solid secure connections..
You dont have to connect the old stuff but i didnt like the thought of cutting it out . or leaving it taped (where bare) and hanging around in there . or even zip tied in tight would probably bother me (im obsessive)
Ive tried to get the power to drain at idle by leaving everything on full blast (subwoofer too) and cant get the volt gauge to budge! (gonna have to run the winch and see if thatll do it
Im shure 5-90's wires would be crimped better and probably not taped but secured a better way. and would be way more convenient as you dont have to cut to length and crimp..
But this way was cheap easy and in no way temporary for me
