Running Power Wire through the Passenger Side

Hey guys, I need to run my power wire from my battery on my NNBS 2008 Sierra Crew Cab. I know you can run it under the brake booster, but I dont think I have enough wire from my previous installs to run across the engine into the master brake booster. I currently have it ran through my door jam and it has worked perfectly for the past 4 or so years, but I know its a lazy way to go and its a newbie way of running it and Im no newbie to car audio as I have been in it for over 10 years.

 

I used the search option and didnt come up with much of anything. Does anyone have any experience running your power wire? This has really been bothering me, even though its not getting pinched. Plus if I can run the wire through the passenger firewall somewhere, I can gain a little bit more length in wire. I am also going to be running another run of 1/0awg wire since I am running 4 amps. Two 1800wrms amps @ 1 ohm, one 4 channel amp and a Phoenix Gold Tantrum 500.2 I am about to install so it looks like I need to run another run of power wire. Haven't decided if I am going to run Cadence 1/0awg wire on top of my Kicker 1/0 wire or a run of 4 gauge wire that I have from Earmark. I have the Big 3, XS D3400 battery that has some serious power for a Group 34 battery and a Mechman 270a alternator

 

Thanks

I too wanted my power wire on the right side without running wire across the truck. What I did was pull the right front fender liner out and right next to the evap core drain is a flat spot of firewall with nothing on the other side(in cab). I took a unbit and carefully drilled a hole to the left fo the drain and used a gromet made by stinger then passed my 0g wire through there. If you drill in the right spot the black under cover below the glove box will cover the wire. I then ran my wire down the center of the truck under the carpet to behind the rear seats. Under the hood the only part of the wire you see is the battery connection. The stinger piece is a water tight pass through and makes for a very clean install. Lot of work but the final result is worth it to me.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Thanks - I wasn't quite caffeinated this morning. 2:1 makes sense, turning the crankshaft 360 degrees will turn the cam 180 degrees, and had I done that, the cam's dot would be at 6 and the crank's at 12 again.   I went ahead and took the sprocket off anyway, aligned everything dot-to-dot including the balance shaft just for s&g. I'm glad I did because I discovered no Loctite on the timing sprocket bolts. Maybe it's not required, but at only 20 ft-lb torque spec, those bolts aren't in there very tight. Cleaned and reassembled with some thread locker and torqued.   A general observation: Less is more with RTV. If a little doesn't stop a leak, a LOT probably won't, either. RTV is thinly veiled revenge, in a tube...

      The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge

      Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).

      PF63 Oil Filters Going Away?

      By Grumpy Bear · Posted

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.

      It also depends on what criteria someone is using for “best” when talking filters.  Are we going off best efficiency?   Best quality/QC?  Etc. because the two may not mutually exclusive.
