mrdavebasshead75 Posted March 17, 2012 Report Share Posted March 17, 2012 I have 2001 Bravada with the 4.3. Engine bay is the same as a Blazer. Im trying to find the engine ground to do the Big 3. Also, does anyone know a spot to drill to put the wire thru the firewall. Im only doing one run of positive 1/0 and running a Planet Audio BB2400.1. If you have pics that would be GREAT!!

beatinpearls Posted March 18, 2012 Report Share Posted March 18, 2012 (edited) You see the two bolt holes on the bottom of the block. This is what I used on mine. If they are available then have at it. Edited March 18, 2012 by beatinpearls Quote Link to comment Share on other sites More sharing options...

kickass audio Posted March 18, 2012 Report Share Posted March 18, 2012 (edited) I have the same style engine and connections but i have an Envoy instead. I grounded from my battery to the bolt that holds the huge metal bracket that is above the alternator (you are supposed to use it as the grounding location when jump starting and it says "gnd" on the part) and i drilled a hole on the frame near the very front and bolted a ground to the frame after i cleaned it up. I have 0 resistance in those connections and its easier than using the bolt on your alt as the alt is a pain in the ass to get to unless you pull your wheel and fold back the wheel well and get to them plus its hard to fit a ring terminal on that connection to begin with. edit: for the wire run i used a pair of carpenter scissors and cut the huge rubber grommet that goes from the inside of my engine to the bottom of my firewall. If you look under the master cylinder there is a huge black rubber grommet that is about 2-3 inches big, i cut a hole through the grommet and fed my 1/0 through that. Then i pulled my carpet back and removed the foam foot rest block and cut a slot into it so that my 1/0 would fit into that neatly and not make a bump on the carpet then continued to run the wire to the back right next to the clips that hold down the bottom trim pieces.

mrdavebasshead75 Posted March 19, 2012 Author Report Share Posted March 19, 2012 What about under the truck? Any suggestions since it'll only be one run? It looks too creepy to go thru the firewall!!

kickass audio Posted March 19, 2012 Report Share Posted March 19, 2012 I havent ran any wires underneath my truck yet but this summer i will because im not drilling a hole in the same grommet again and try to fit a ground wire next to the power wire on the same run. I planned to use the cargo bolt that i modified in the rear as a junction so that i will have one end of my ground connected to that and then a continuous run to the ground of my battery under the hood. I was thinking to run that right along the outside of my frame rail up near the top so its out of the way. Havent looked into too much detail for if its possible but i will find out this summer when i jack it up and look at it. lol. The firewall is way easier but that grommet i used is a pain in the ass to cut through since it has a solid rubber center on it and i went very slowly so that i didnt slip and cut the wire harness that comes in from there. I then made the hole just big enough to fish my 1/0 through it but it was super tight so i would have no water leaking through it. Then to finish it off i took air conditioner putty and put that right around the outside of the wire for extra waterproofing. Im overkill with a lot of things but id rather be safe than sorry. haha.

mrdavebasshead75 Posted March 19, 2012 Author Report Share Posted March 19, 2012 I really appreciate the help guys!! But I think ill give the underbody a try with the run, might even do two runs while im at it. Im still bumped on the big 3 tho. I dont have a bracket that says "ground" above the alt. And I found the engine block ground but its so deep I cant get to it!! I might drill a hole to the frame and send it there then to the battery and then chassis to the frame! Would that be safe??

kickass audio Posted March 19, 2012 Report Share Posted March 19, 2012 Here are some pics i took with my phone of where my power and ground wires are in the front of my envoy. Your truck may not have the ground block i was talking about above the alt but see in the pics. This is the ground location on my frame underneath the battery tray on the drivers side frame rail. I drilled the hole, used a wire brush on a dremel to scratch the frames paint off and then used my dads tap and die kit to put threads into the frame and bolted the bolt to the frame. That bolt is the tightest one i put on my frame. My rear ground was a pain in the ass. picture 1 of the location where my +12v 1/0 goes into the firewall through the cabin. I couldnt get a pic of it in the cabin because i didnt want to tear down the lower part of my dash where my alarm is, too many wires down there. lol. power and ground wires between my engine/alt and battery. the wire going from the black terminal on my battery that is in the ribbed cover is the ground wire for my engine. It was easier to put it up there.: again.
